Title: rear sprocket
Post by: rosco on July 27, 2019, 12:57:01 PM
Just fitting a new rear  sprocket and it seems a lot of play Not much rotational just a little bit of movement within the bolt holes of the sprocket The bushings seem ok But lateral play there is at least 1/8" old money Is this the norm ???    Also the rear spindle The PO has put it with the nut on the sprocket side Looking in the parts catalogue thats right   Yet in the service manual shows nut on brake side which i believe to be correct Your thoughts appreciated Cheers Ross

Nut on brake side because to remove the rear wheel, you would have to remove exhaust to get the spindle out if it was on 'tother side. I have a little lateral play on my rear sprocket as well (Thinner pattern part). Both wheel spacers are different sizes, make sure you get the correct one on the correct side. The longer of the 2 goes on the brake side.

If you look in the Honda manual it shows the nut on the sprocket side . If the swing arm has open fork ends then it makes no difference which way the spindle is in as it doesn't have to be removed to take the rear wheel out.

Bloody weird....I have just looked at my CB400/4 (standard closed end swing arm) and my nut is on the sprocket side but, I can still get my spindle out as I have a standard exhaust system fitted and there is enough clearance over the silencer to pull the spindle out with the exhaust still fitted. My shocks are also standard length, anything shorter than standard, I don't think there would be enough clearance to pull the spindle through.

I'm just wondering if the shop manual, being combined general 350/400, (but with the 400 supplement at the back) shows the 350 set up which has the 4 into 4 exhaust 🤔. Does the 350 have an open end swing arm? Also just noticed that if I put my 400 on the center stand, then I can't get the spindle out as not enough clearance over the silencer 😪

The parts list shows the early swing arm with open ends with the footrest brackets on I can't find later ones I guess they must have gone to closed ends then. Makes sense though to put the nut at the brake side as it keeps all the chain crap off it if you ever need to remove the wheel at the side of the road.
My 350 has open ends but then it's a very early  350

Scrap that..my 400 does have an open end swing arm 🙄🙄🙄🙄 So, it doesn't matter which way the spindle goes in. (I was looking at the wrong bike 🤣🤣🤣🤣)

So to conclude   It won't matter which way the spindle fits if you have open-ended swing arm  But if closed end Nut on brake side so spindle drawn out nearside. Think i will fit nut to brake side although i have open-ended arm

I don't think you will get the nut on the brake side. If you look at the pics, the spindle sticks out a lot more on the nut end than the other end. If you turn the spindle round, the silencer will foul the end of the spindle and you won't be able to get the nut on if you have a standard exhaust system fitted.

For what it's worth, I have 400 with fixed rear footrests, closed ends swinging arm. Nut is on RH (brake) side, when assembling, push spindle through from sprocket side and when enough thread is showing start turning nut and use this to pull rest of spindle through. On the spindle I am using at the sprocket end it has a hole whereby you can use a small tommy bar/screwdriver to hold the spindle while you tighten the nut, would not be able to use this if it was at brake end. Little bit of care needed when inserting split pin into castrated wheel nut. Sorry Julie, but speaking as one who made an absolute pig's breakfast once of trying to fit shox that were too long, that's when everything fouls up. Always carefully measure between fixing centres of shox before trying to fit, can't give proper measurement at moment, as it's absolutely precipitating down outside, and the pizza and beer are ready. Regards, Michael.

Agree Michael. My shocks are spot on the original length so everything is sitting where it should be as far as levels and clearances are concerned. But, although I can see its very easy to insert spindle from the nearside, making the nut on the off side by the brake, I cant see how this is possible with the silencer in the way, if a standard exhaust system is fitted, there us just not enough clearance available 🤔🤔🤔

Just found in Haynes manual page 97 section 7-1 It states Pull out the spindle with the drive side adjuster and spacer As Trickymicky states would make it difficult fitting a tommy bar to assist removal

Yes Ross, it does say that, it also says that's for the CB500 closed fork ends 🤔

I'm not saying mine is correct being inserted from the brake side by the way 😊😊 What I'm saying is that I can see why I put mine in that way, purely because there is not enough clearance for it against the silencer if I had put it in from the other way.

Even David Silver puts it in same way as me 🤣🤣🤣

So you can still insert a tommy bar without fouling the exhaust??  Or was the wheel fitted then the exhaust

Not sure you have the correct spindle for a 400/4 then. If you look at my photos, you can see the spindle is a fixed nut on the end. You don't need a tommy bar or screwdriver to put in a hole, as there is no hole. It sounds like you have a 550/750 style spindle with the big round chrome end on it and not the nut end like mine.

Who's right and Who's wrong That is the question???  lol  TrickyMicky has an early 400 with footrests on the arm and his spindle is the same as mine His arm are closed ends Mine are open end  So maybe i have the early style spindle with later style arm !!!!! Parts catalogue shows both type arms but only one type spindle?Don't know why ??

Just been looking in to this Ross. Both you and I have F2's which have the open ended swing arm, which we both have. Up to VIN number 1065686 (so a lot earlier than ours) they had the spindle with the big chrome end on, with the hole, which is the one you have I assume. This style was a hangover from the CB350/4's of earlier years. After the above VIN, they fitted the fixed bolt type, like I have fitted on mine and what you should have fitted on yours. Why Michael has a closed end swing arm, I have no idea as all 400's were manufactured with the open end type, again, a hangover from the CB350/4. I'm sure it makes no odds which is fitted really as long as it does the job.

Y'know, once upon a time, there was a bloke who had a good memory but it was very short. Due to internal repairs needed, the bike has not even been looked at since last November. Unfortunately, DSS does not sell the required bits so it's in the hands of our beloved NHS! Dear Nurse Julie, (be gentle with me when the time arrives!), your comments re. rear wheel fittings re-activated the grey matter, and lo and behold, yes, I did have to obtain a replacement rear spindle, and it is the type requiring the use of a tommy-bar. Because of the size of the chrome end it could not be fitted in from the RH side, but as the spindle is pushed through from t'other end you have the castellated nut in position waiting to meet it and then use this to wind the spindle all the way through. I still have enough clearance between OE silencer and nut to be able to use a decent size ring spanner. The operation needing the gentle touch is inserting and folding over the split pin. I didn't word my previous message very well, when I said I had fixed footrest, I meant that they were frame fixtures and not knee benders! Having looked at some of my earlier photos, much to my amazement I see that my swinging arm fork ends have actually got slots! Notta Lotta people know that. I will endeavour to try and upload a couple of pics, but it keeps telling me they are over the limit. If its got 18" wheels and metric nuts I'm ok, but computers - NAH!

Oh Yeh, just one more thing, when purchasing a hydraulic bike lift, temper one's enthusiasm and measure the length of the platform first!!!!! As you can see, rear wheel fitting gets very interesting, hence the need for our beloved NHS!

Yours is an interesting bike Michael, being an early one by registration but with the frame mounted foot pegs. I know there was a time when the early ones which normally had the swing arm mounted pegs, had the later frame mounted ones but I cant remember where exactly in the production that was (I also have mushy brain syndrome).
Edit....had to look it up 🙄🙄🙄 1976 model year went to frame mounted foot pegs but was still in the early colours, ie Light Ruby Red and Varnish blue. Also had a locking fuel cap fitted from 76. So still an F model....not the F1 model.

Just had a look at DSS and they list two types  The type i have (chrome end for tommy bar ) is for the  F & F1  The long bolt type Julie has is the correct type / style for the F2 Although the parts manual lists this as fitting F & F2 So i guess they are interchangeable as the bearings are the same for both   Ross

I wonder if  both types are the same length overall Ross? Would be interesting to know just out of curiosity really. But, as you say, they both fit and do the job and that's all that matters.

Mooney is quite right. I'm sure the Clymer manual clearly says that on the 400f you remove and replace the whole rear wheel assembly without needing to remove the spindle and adjusters.

Yet another caffeine intake has spiked the memory bank again, and guess what?  Quite a few years ago I purchased a pair of replacement shox purported to be just like the "Real Thing". Yeh they looked fairly similar, so off came the rusty OE ones, (which still worked ok). had to change all the fixing eye rubbers etc., and on they went, nearly! Had I measured them? Nah! They were fractionally longer which meant the wheel spindle fouled the silencer. Solution - elongate the fixing hole for silencer and slide it out a fraction. Solved - Nah! They were that long that when bike was on centre stand the rear wheel was nearly touching the floor still and when putting the stand up it missed the rubber foot and fouled the chain, Oh blow! Adjust rubber foot slightly, take bike off stand, sit on saddle and could barely reach the floor!! Bugger this, purchased the ones seen in pics, perfect copy and size, move silencer back just enough for centre stand to connect with rubber stop. THAT'S the reason I can fit spindle with nut on brake side! All that needs checking now is the nut un the saddle. Regards, Michael.
