I had no issues Mike  when I did my 400 rear wheel so I was well miffed when the 500 did not work out first fit.

After chatting to Ken on reflection I obviously did not fit the right side bearing fully home. The 500 has that short extra spacer that fits into the left bearing as well as the long center spacer. Make sure you fit the short spacer fully home  into the fixed left side bearing before you fit it.

It's different but the same in some aspects as the old Mini Cooper S had taper roller bearings in the front hubs that were not adjustable you just torqued them up. The other Minis all  had plain ball bearings.

Project Board / Re: Teds new project a CB500 K1 mostly version 0.5 circa 1972.

Just keeping the project progress up to date - sorted out the wheel binding when I tightened up the axle nut - turned out to be a combination of the right wheel bearing not being knocked in fully home plus some brake shoe binding as per my 500 advice sought post on wheel binding.

Rear wheel now fitted, chain fitted together with rear brake rod / adjuster and hub bar thingy. Now the bike has two wheels fitted I need to remove the center scissor stand and torque up the sump and various other bits like the front wheel clamps.

I have a list of items to check for tightness and add my yellow dots when done. My plan is to start fitting the exhuast system in the next couple of weeks.

Photo of bike to date.

  Went fishing yesterday (Weds) for a couple of hours in the early evening.

Ted, you have just completed something a younger mechanic would fail at mate.
By the way the chain whilst new was not an expensive one

It's marked DID on the links so I'm happy with it to go back on - it's not going to see much mileage in my ownership.

My target date was to have it running for my birthday - I've missed that by two days already. As I have my 400 to use I'm in no hurry to get it finished this month - it's still not very warm in my garage either.

That's a real pain - at least you have found the issue.

Misc / Open / Best way to lubricate none O ring bike chains question?
« on: May 07, 2024, 10:48:16 PM »
My chain was replaced and was ittle used when I purchased the 500 from Bryan.
I have removed the light surface rust, after cleaning I have sprayed it with some chain lubricant that I have on my shelf it's a black coloured foam type grease called "IZUMI" Racing Japan that was given to me.

I have read online about a product called Putoline Chain Wax - not cheap but it sounds a neat idea to heat it up so the lubricant fully penetrates the rollers etc.

What do members here recommend as a good lubricant?

I was quite pleased with my Flap Wheel that I bought from Scewfix - trouble is it will not fit in the gap between the hub brake lining and the center of the hub - I'm sure it will come in handy in the future!

Undetered I decided to use a pair of those  dark green plastic wheels that Ken uses for polishing work. A steady five minutes with them in my Dremell,  the brake liner cleaned up really nicely. Hub fitted back in the wheel,  nipped up,  a couple of high point rub marks on the brake lining near the middle towards the edge of one brake shoe. Hub removed some sand paper on the high points, Repeated twice - all is now as it should be - wheel rotates freely at last!

I've lost count of how many times the back wheel has been removed and re-fitted over the last two days - it was worth perservering to get it right.
Thanks for the tips from those who replied to this post.

Thank goodness for my bike ramp it made it all so much easier - time for a Beer reward!

I have filed down the shoes to enable a washer to be fitted under the split pin.

On closer examination of the brake shoes alloy plate there were a couple of what looked like rub marks on the alloy shoes on the outer edges. This was just on the one shoe. I have done some very light filing of the edge  it has reduced the binding substantially when the axel is tightened up.

I am collecting a flap wheel today as well - Bryan -who sells Vesrah brake shoes in the UK?

The brake binding is not present until I tighten the axle as I increase the tightness the binding starts.
To make sure it was not the bearings  I removed the linings re-fitted the brake hub - all free.

The only thing that really changes when it is tightened up is the inside edges of the brake shoes are closer to the inside of the wheel. There is no sign of any lip on the liner.

Where the liner meets the wheel internals it looks visually good with no sign of any lip. It might be worth doing some very slight sanding on the inside edge of the brake shoes or even a light  shamfer on the outer circumference/edge of the  lining.

I did wonder if I could mark the outer edges with some yellow road chalk and see  where it transfers to.

Thanks Bryan - a few minutes ago I took out the brake hub- removed the shoes - put it back into the wheel - torqued it up rotated freely - so it's just a very close fit - as it was when I first rode the bike.

The Shoes look like the DS ones they are marked SOK 283 .

Bryan I have never had a flap wheel so how are they sized can you post or PM me a link as to the size & grade I need please?

I assume they will fit a normal drill.

Petrol floats in Diesel so it will probably soon soot up the plugs then start to misfire.
Anecdotal Story
It was a long time ago but an lovely Irishman (Keith Dunne) I worked with used to put diesel in his petrol car to save money as in the 1960's it was cheaper- he drove a Standard Vanguard - it would smoke like the clappers and eventually it seized up.

Personally I would consider draining out the tank and start with new petrol - diesel is not good for the piston rings.

Not sure if the diesel will seperate out when standing or if the two hydrocarbons are compleltly miscible.
