Title: 1977 CB550
Post by: Valentinik on January 09, 2016, 10:51:13 PM
Some will have seen my introduction post but if you haven't, First of all, this is the first bike i've owned and its a big learning experience more than anything for me, i've had numerous cars and I'm currently build a turbo westfield but bikes are something i have never worked on. So please excuse what some may feel are stupid questions.

Today i went and collected a new project. Its a 1977 CB550 K3, it looks like someone has changed the forks to super dream items as well as the wheels. Im hoping to find some good used items, refurbish them and replace them. As can be seen from the pictures, some bits are missing and its not in too good a state but something i thought was suitable to work on.

I went and collected the bike from leominster this afternoon. To pay my wife back for coming with me i had to take her out to dinner so wasn't able to start until we got back (she wasn't pleased).

Here it is before it was put in the garage:

I've removed the seat, tank and exhaust and just had a look at what exactly is missing and what i need to do:

(http://i1356.photobucket.com/albums/q739/S2-Roadster/CB550/7ADD6C69-FA92-4FB5-8F8C-CABA3835D3BA_zpsdknwzhug.jpg) (http://s1356.photobucket.com/user/S2-Roadster/media/CB550/7ADD6C69-FA92-4FB5-8F8C-CABA3835D3BA_zpsdknwzhug.jpg.html)

One thing I'm not sure of what it is/where it is meant to fit is this:
(http://i1356.photobucket.com/albums/q739/S2-Roadster/CB550/BB9D0268-FDD8-4B09-9821-16361656E0A1_zpsixkxzmec.jpg) (http://s1356.photobucket.com/user/S2-Roadster/media/CB550/BB9D0268-FDD8-4B09-9821-16361656E0A1_zpsixkxzmec.jpg.html)

Could anyone give me a pointer on what it is?

Brake light switch that attaches to the rear brake lever

If you haven't already got hold of them I'd suggest getting a copy of the Parts List and Workshop Manual from here:
http://www.sohc.co.uk/index.php/topic,8884.0.html
Personally I have found a parts List to be far more useful than its name might suggest.

if you need a bracket and spring I have new ones I was going to put on ebay.
Title: Re: 1977 CB550
Post by: Norniron on January 10, 2016, 02:17:41 PM
The brake light switch attaches to a bracket, on the 500 and I'm fairly sure the 550F it's a bracket welded to the frame, on the 550K however it went into a bracket which was separate and attached to the upper rear engine bolt, probably why it's loose as on the 500 and 550F you wouldn't really need to remove it. It's missing a long thin spring which goes through the hole in the pin you can see protruding from the switch.

If the carbs are missing I'd fit the carbs off either the 500 or the 550F as the 550K carbs were much different and TBH are pretty pants in comparison. You'd also need the airbox to match but it's a worthwhile change as the 550K carbs really are that bad.

Good advice from oddjob about the carbs.But u also have to change the intake manifolds on the back of the head.Your intakes wont line up with the older style carbs

Thanks everyone, its all really useful information to me, i've learnt so much already. Il keep an eye out for some carbs, the frame is the first thing I'm going to be working on though. So i've got plenty of time to gather the bits together.

I made a little bit of progress this morning. Both wheels are off, the engine is out and i've taken a look at the forks. The chrome seems to be pretty rusty and I'm not a fan of the wheels, so i may see if i can source a set of original forks and spoked wheels.

(http://i1356.photobucket.com/albums/q739/S2-Roadster/CB550/F172873F-9878-418F-A939-DCA2661D044B_zpsfuzhuudg.jpg) (http://s1356.photobucket.com/user/S2-Roadster/media/CB550/F172873F-9878-418F-A939-DCA2661D044B_zpsfuzhuudg.jpg.html)

Before i took the engine out though i wanted to check it turns over as i didnt know what state it was in. The good news was it turned over quite freely. The less pleasing news was when i drained the oil, 2 litres of water came out before the oil.

As you can see from the picture theres a bit of rust on the camshaft and tops of the valves but I'm hoping its still useable. Im planning on a full engine rebuild anyway.

Once you get inside the engine, check the journal bearings under that camshaft, have you got a rocker cover? Also check the valves are seated and not bent, Hopefully the water will not have been in there too long. I would think the twin disk setup and superdream front forks should be easy to re home.
Title: Re: 1977 CB550
Post by: Valentinik on January 10, 2016, 09:31:20 PM
Thanks guys, Is there a specific year of carbs/inlet I would be looking for?

Unfortunately I don't have the rocker cover. I think that is the reason for all of the water ingress, it seems like it has been left outside for a while.

Are the rockers and cover specific to the 550, or would a 500 set work if i can get them?

As I'm not going to get around to the engine build yet, i wondered if it would benefit at all to fill the engine with some fresh oil that i've got spare?

That's great thank you. Il keep a look out for them.

Before I remove the wiring loom I'd like to test that everything works. However the ignition switch is faulty ( it's held together with a cable tie).  Is there a brand of switch that's ok to use? Or should I go with a genuine Honda item?

Brilliant, ordered along with a spark plug spanner. I've decided to strip the engine down now and clean all the parts. Hopefully to try to protect them from any further damage. Just incase the water hadn't been in there too long.

My Ignition switch arrived today. So i hooked a battery up and tested everything. Everything seems to work, the only issue i can see if that the rear light is constantly on. The light switch has no effect on its operation, when the switch is moved the light flickers ever so slightly but nothing more.

Is there anything i could look at that may be causing it?

Thanks

If its a Canadian Bike (or perhaps a US Bike supplied to certain States) the lights are often linked to the ignition.....i.e. Ignition On = Lights On.

I had a Suzuki GT500 which I bought new in 1976 when I lived in Canada and that always ran the lights as soon as the Ignition was switched on........I had no problems with that set up but if I remember correctly it was the law at the time in Canada.

Worth looking into......maybe a UK market switch might solve the issue.
Title: Re: 1977 CB550
Post by: Valentinik on January 13, 2016, 08:29:57 PM
Thanks, that thought did cross my mind. Il take a look. When the switch is unplugged the light also stays on, i don't know if this makes any difference?

Sorry i didnt phrase it very well. The tail light goes out when the ignition is turned off, but it come straight on when the key is turned.

I presumed it should only come on when the light switch is used? Or am i mistaken?

Post by: Valentinik on January 14, 2016, 05:34:39 PM
I haven't got any lights on in the headlamp.  I've now disconnected all of the plugs in the headlamp and when the ignition is switched on the tail light still illuminates. So the connection must be elsewhere.  I've attached a picture of the frame plate and headlamp switch

It could be that a previous owner had a break in the loom somewhere, and rather than sort it properly has bodged a new wire or supply to the tail light, which is live all the time the ignition is on, with no way of switching it off ( seen it done a few times over the years) If it is an issue to you, do a thorough inspection of the entire loom and all it's connectors, looking for any odd/unusual looking bits of wire or strange connectors like the dreaded scotchlocks!

Thanks for the info both, I checked the fuse box, it looks very clean, no corrosion. The only time the light goes off is when this fuse is removed:

(http://i1356.photobucket.com/albums/q739/S2-Roadster/CB550/C4071C97-1A54-4D03-BA30-A29622DEEB12_zpswkre8ztg.jpg) (http://s1356.photobucket.com/user/S2-Roadster/media/CB550/C4071C97-1A54-4D03-BA30-A29622DEEB12_zpswkre8ztg.jpg.html)

If either of the other fuses are removed the light stay on.

I then stripped all the tape off the loom and found no wires spliced that shouldn't have been. The only issue i found is the positive feed from the solenoid to the mulitplug that feeds the main loom, the red 12v+ wire was quite corroded and broke while i was examining it. I may replace these with modern waterproof connectors in the seat pan I'm going to fabricate.

I doubt this would be causing the problem with the light. To sum up, the light operates with nothing plugged in, only the main loom connector to the solenoid and the ignition switch, in the on position, not P.

I made a start on stripping the engine down to try and limit any damage from any water. Tonight I got the head and cylinder removed, so far I'm pretty pleased with what i've seen. The bores look to be pretty good with no visible scoring or lips, so I'm hoping i can use it without a rebore. The only bit of damaged i've found so far is a slight mark on one of the pistons.

You can see the damage in the circle. After i've got it all stripped down and inspected i want to get the cases painted/powdercoated, is there a preferable way to clean the crankcase. Vapour blasting, etc?

The logbook for the bike arrived today. Which pleased me as the seller never had it when i purchased the bike, against my better judgement i bought it anyway (after doing a HPI).

Anyway, i made a little progress tonight.  I never mention when i started the topic that I'd like to go with a brat style with the bike. I know its not to some peoples taste but i've always liked that style of bike.

With that in mind, i started on removing some of the brackets from the frame that i won't need. Side panel mounts, battery tray mount,etc.

Before

I only got one side done as it was getting late but hopefully tomorrow i will finish the other side off. Im not sure yet if I'm going to cut the rear of the frame slightly and weld an upswept hoop in like this:

(http://i.imgur.com/Mkzqp3y.jpg)

Or just remove the bridging section between the 2 sides weld a brace in to mount the seat to.

I've just got a few smaller sections to tidy up and then i can cut the bridge at the back. I also got an impact screwdriver and undid all the bolts from the clutch housing, so i can carry on with stripping the engine.

A question: I've read a lot of topics on keeping the standard airbox and filter. Seeing as i don't have the airbox and the carbs i buy will need rebuilding/rejetting to suit the engine. Other than having to rejet the carbs which i would have to do anyway is there any other issue with using pod filters instead of the standard airbox?

Thanks

I finished off stripping the engine down tonight. The only sign of damage i've found from the water is a small amount of rust on the primary drive gear on the crankshaft. I haven't attempted to clean it up yet but I'm hoping il be able to.

Pistons and top crankcase removed:
(http://i1356.photobucket.com/albums/q739/S2-Roadster/CB550/9FFA5756-18FB-4974-A35F-233A6CD9CE59_zpsz9j05rsy.jpg) (http://s1356.photobucket.com/user/S2-Roadster/media/CB550/9FFA5756-18FB-4974-A35F-233A6CD9CE59_zpsz9j05rsy.jpg.html)

Unless you have a problem with gears leave the drum in there but as you are that far down at least a primary chain is a good idea, you can just see the marks where it has started to touch the oil gallery

I also made a small battery box and welded a bracket underneath the swing arm to mount it. I just need to weld the aluminium box up

I made the aluminium panel for the seat tonight and mounted it to the brackets i welded on the frame. The bolts are only temporary.

The brake light switch attaches to a bracket, on the 500 and I'm fairly sure the 550F it's a bracket welded to the frame, on the 550K however it went into a bracket which was separate and attached to the upper rear engine bolt, probably why it's loose as on the 500 and 550F you wouldn't really need to remove it. It's missing a long thin spring which goes through the hole in the pin you can see protruding from the switch.

If the carbs are missing I'd fit the carbs off either the 500 or the 550F as the 550K carbs were much different and TBH are pretty pants in comparison. You'd also need the airbox to match but it's a worthwhile change as the 550K carbs really are that bad.

With reference to this post oddjob made about fitting some 500 carbs. Im looking at buying some but i wondered what year 500 bike would i need to be looking for and what  the model of the carb is?

Thanks

A question about the primary shaft installation if someone wouldn't mind answering. In the manual it states this:

(http://i1356.photobucket.com/albums/q739/S2-Roadster/CB550/Screen%20Shot%202016-02-24%20at%2021.16.39_zps3vqlgifz.png) (http://s1356.photobucket.com/user/S2-Roadster/media/CB550/Screen%20Shot%202016-02-24%20at%2021.16.39_zps3vqlgifz.png.html)

I can't see any markings on the starting gear and clutch to indicate how to position it. Is the position of them important and if so, how do i go about aligning them?

Thanks
Mike
Title: Re: 1977 CB550
Post by: Bryanj on February 25, 2016, 05:40:34 AM
It isnt important, BUT ignore the boolk and build everything into the top half of the crankcase thaen after case assembly you can refit the primary shaft by holding the starter/primary gear through the sump hole. This way makes it a lot easier to get the selectors etc to line up
Title: Re: 1977 CB550
Post by: Valentinik on February 25, 2016, 01:46:17 PM
Thanks both, that's really useful. My next question was going to be about how to align the gear selectors.

I've left the selectors assembled on the drum but I can't see any mention in the manual about how to align the gear and selectors in the right place. Is there a picture of the gears in the correct position I may have missed somewhere?
Title: Re: 1977 CB550
Post by: Valentinik on February 25, 2016, 07:53:24 PM

Make sure you also renew the primary shaft dampers along with the primary chain, it will last a lot longer if you do and will also be far quieter as they tend to go hard and lose their damping ability as a result.

The primary chain was already on my list as it had started eating its way into the crankcase, but i'l add the dampers as well.

Thanks, I double checked the roller bearings were located over the pins as at first it didn't sit in position, but they sit down correctly now. By setrings, do you mean the half moon bearing fitted in the bearing groove at one end of either shaft?

Thanks for the pointer on the oil seals, i had presumed they would have been fitted after the cases were joined so it has saved me making the mistake.

Other things have stopped progress for a while but i found a set of forks on eBay complete with triple trees. They're in very good condition, the trees will need powdercoating and i'l replace the oil and seals but they're fantastic for £52 posted.

No progress for a while apart from collecting a few smaller parts, but I'm just about to order some bits to complete the engine rebuild.

Apart from a full gasket set, primary chain and primary dampers and cam chain, is there any other parts i should look at replacing?

I recall i've seen somewhere an alternative part for the primary chain  and maybe the cam chain swell that may be cheaper than DS, could someone point me in the direction of where to find one if i wasn't imagining it?

Thanks Trigger.

No progress pictures but i got the frame stripped down completely and took it to to be blasted and powder coated as well as the swingarm and yoke. They're quite busy at the moment so it may be a couple of weeks before its done.

On the way back i stopped into the local Main dealer and got the primary rubbers and a few circlips that needed replacing as well as some new shock bushes and oil seals. DS didnt have all of the parts in stock, so i have't got all of the bits to rebuild the engine at the moment.

The larger bits came back from the powder coaters today. Im really pleased with the finish, its 99% perfect and only cost £96 all in.
 
I found a prime position to start the build:

The wife didnt have the same opinion on where the build should continue so it was relegated to the garage. (it made it longer than i expected)

Fit the engine to the frame with an engine crane. Or position the engine on the floor on its side, and fit the frame around the engine?

With the CB750 definitely put the engine on its side and lower the frame onto the engine, I'm pretty sure the same method is best for the 550.

A question RE: swingarm installation.

When installed and the pivot bolt torqued, should the swingarm fall under its own weight or stay in position?

I have torqued the bolt to 38lb ft and now it is torqued up, when released the swing arm stays in position and doesn't fall. Is this correct?

Oddjob, yes i've had blown out and cleaned the swing arm before i did anything else. The chain guard brackets have been removed as i don't intend on using the chain guard.

Thats good to know about the engine, is it possible then to fit the cylinder barrel with the bottom end installed in the frame, or is it better to fit it before fitting the engine to the frame?

Following Oddjob's advice of fitting the engine to the frame partially assembled I started assembling the first few bits onto the frame.

My tapered steering bearings arrived today so I've now got the yokes installed. I fitted the swingarm during the week. This is how it stands at the moment:

Is it easier to wait until the wheel is built and then change the bearing Mike ?, I don't know if the 550 is the same as the 750 but on the 750 the retaining ring is centre dotted to lock it in position, I took a fine drill and drilled out the centre dots , I'm not sure if there's another way but someone will say if there is .

Thanks Mark, i wanted to strip it down so i can have the parts blasted and powder coated so it needed to be done before the wheel is assembled. I've now got it stripped down and the bearings removed, ended up holding in a vice between 2 pieces of aluminium to protect it. I made a tool to remove the retainer ring.

Title: Re: 1977 CB550
Post by: Trigger on July 15, 2016, 09:15:48 PM
Me thinks that SI5980 is just silicone sealant, you want something that does not dry.
Hondabond or Hylomar is cheaper, it needs to be a thin layer or it will squeeze out in to your engine. I always put it on the case and scrap it with a plastic card, leaving just a tacky surface.

My oil seal arrived today so I got on with building the engine cases back up.

I got both cases mounted together and the primary installed:

I have also installed the gear shift:

A concern I have though is, there seem to be 2 small issues with the casting either side of the shaft, shown in this picture. Is this something I need to be concerned about?

I also collected the remainder of the parts from powdercoat

I've also ordered the tyres for the wheels so hopefully will drop the wheels off to be built with new spokes at the weekend.

Thanks, I think I did like the look of the bolt head being the same colour as the case in this instance. For the less (torque) critical bolts I was planning on using stainless cap heads where I can. (Covers,engine mounts,etc).

You are correct, the gear shaft seal was missing when I took the picture but it's been installed now. Along with fitting the Pistons to the rods.

I took the tank to a friend today who is the paint shop manager for a very large dustbin lorry manufacturer as he offered to paint the tank for me.

I try to do as much of the work myself and to learn new skills as I go. However, the equipment he's got to use will undoubtedly give a better result than me doing the job myself.

The colour I've chosen may not be to everyone's taste but I'm hoping it will suit the style I'm going for.

The tyres and new wheel bearing arrived today. I got on with pressing the bearings in so I can take the wheels to be built up at the weekend.

Thanks, the spokes will be satin black also.

It's probably a bit too much black for some tastes but I've never really been a fan of shiny things like chrome, stainless etc. So I'm trying to limit the amount used to bolt heads etc.

I started rebuilding the forks today. Got the new seals installed and everything In place but have A question.

What torque should the 8mm Allen head oil lock bolt at the bottom of the fork be tightened to? And should thread lock be used on it?

I did take a look in the factory manual but the bolt descriptions weren't clear to me.

Thanks

Mike

Just do it up tight is enough and only use threadlock if you want it to be a swine to change seals again BUT do make sure the copper washer is in good nick

Spent some time over the weekend, getting the forks on and the partially built up engine I'm the frame. I can get on with finishing the engine build off now.

A question, I have a new gasket for the clutch cover, do I need to put and hylomar on this gasket or should it be fitted dry?

Thanks

No sealant needed, although some people smear the gasket with grease, helps stop it sticking and tearing if you need to do any further work inside.

I had planned on fitting the rocker cover. When I removed the head I noticed the 6 rubber blanking caps had been installed with some sort of clear sealant. Do they need any sealant fitted or should they just sit in place?

Thanks
Mike.

New rubbers should not need sealant but pattern ones sometimes need A VERY SMALL AMMOUNT.

DO READ THE MANUAL CAREFULLY BEFORE FITTING THE COVER or you WILL bend valves

I must admit I forgot to order new seals up to this point. Is it possible to re-use them or is it wise to replace them?

Thanks

Depends how lucky you feel, 80% of the time you can reuse the other 20% it leaks more oil than the Torrey Canyon

I got the wheels back from the wheel builders today so spent the evening reasembling them and fitting them.

A question, I couldn't see in the manual ( I may be being stupid) the torque spec for the bolt behind the steering stem bolt. Can anyone tell me what the spec is?

This one:

Hi, No youre not missing it anywhere else. I've started on the wiring, i have positioned the starter solenoid and had some power cables made up. Unfortunately thats as far as i have got due to working on my car project and the wife wanting me to do DIY :(

This is a picture i took a few weeks back when i was having a tidy up in the garage. This was the first time it had touched the floor with its wheels on, and the first time i had sat on it.

Small update, i've now got the rocker cover fitted, i just need to source some tappet covers as it only came with 2 and they aren't in the best condition.

I've not had much time to work on the bike since my last update due to moving house earlier in the year so my time has been filled with diy, gardening and lots less interesting things than getting this finish.

Earlier in the year i bought a set of cb500 carbs which i've stripped down to replace all of the serviceable parts and powder coat some pieces.

Over the last couple of days i've ordered a few bits to hopefully get the bike started for the first time (since i stripped it down). I've now fitted the oil pump along with the left had engine cover. Today some tappet caps and new ignition coils arrived. Ive got the coils fitted, just need to sort the spark plug leads out.

The carb bits and tappet caps should go to the powdercoaters within the next few weeks and then i can hopefully make a start on getting it started.

While waiting for the rest of my ignition system to arrive i test fitted the stop tail light that i made. The housing is made from aluminium and the lamp itself is held in with stainless mesh and a stainless circlip.
