Teds new project a CB500 K1 mostly version 0.5 circa 1972.

Just a bit of an update and to give credit to Vince Goosey at this firm who I bought my lock ring tool from back in May 2023. www.gbmotorcycleproducts.com

I today received f.o.c. a set of four pins to replace the ones in my tool that fits the poorly made replica part supplied my DS.
That's what I call customer service.

I decided against sending my lock ring back to DS for them to change it as they were not prepared to do so until the faulty part was back with them to compare- clearly they still have the faulty ones left on the shelf. I did not want to take the risk of them sending the same part out again not to mention the time delay.

Clearly DS knew there was an issue with a batch of their lock rings - they could have sent me a replacement that I would have paid for on the basis of a refund on the returned part. This was an opportunity for them to give better customer experience that they missed.

This morning I tightened up the lock ring with the new pins fitted to the tool.

It's clearly not my day today.

Well, came to fit the oil seal in the retainer and it does not want to fit - it clearly is the right size as it looks as it will fit the old retainer just fine when I tentatively part fitted it!
I dont want to risk damaging the seal trying to make it fit so I am sending the retainer back to DS for replacement.

That's put me back a few days now - I am going to return the DS retainer ring part in the hope that a replacement one is from the new production batch.

Ted, for the life of me I can't remember an oil seal sitting in the retainer. The only oil seal fits in the sprocket fixing plate which the rear wheel collar comes through.
This is a 550 but should be the same.

But I might be wrong!

My 500 has eight rubber dampers four are thick on the drive side four are thinner on the overrun.
Looks like the 550 is different.
Definitely another seal on the retainer item 20 in the parts book p/n 90753-283-000 the left side spacer runs inside it plus a large O ring for the sprocket cover I think.

550 and 500 same shape but later ones had a connector bit, the screwed in retainer does not have a seal, only the big tim pressed plate

So the seal fits into the sprocket cover plate Bryan not the retainer ring - that makes sense.
It confirms what seablower said as well.

I should have taken more photos and listned the first time!

Plan C now used the DS retainer ring having fitted the different pins to my tool - tightened up nice and tight - all looks good

The 500 rear wheel when fully assembled felt so much heavier than the 400.
Seal fitted into the sprocket tin plate after fitting the left side spacer wide end to the bearing. Large O ring fitted to the hub all in place as per the parts exploded diagram.  Spocket nuts nipped down with some new locking washers fitted.

I've done the first fit of the wheel - looking good - not torqued up the sprocket nuts yet or bent the locking tabs into place. I'm worn out now for today.
I'll tighten up the rear axle to check the wheel rotates freely before I fit the chain etc.

[McCabe-Thiele (Ted)]

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.

Thanks Johnny I'm pleased with the build so far. I just hope the engine  starts & runs as my 400 does. It's my forever bike so not worried that it cost around £2k more to rebuild than my 400. I've pretty much bought all my parts to finish the project.

Never say never but this is probably my last project. I'm keeping my first born - my 400,  between the two I should always have a runner as long as I'm able to ride a bike.

Looking good Ted - did you have the rear mudguard rechromed . - ££££££ !

[magpie114]

Looking very good, can’t be too far off. Are the tank and panels finished?

Yes they are already painted in gloss Black in safe storage - done by the bloke in Ilkeston who was recommended to me by a sohc member (Seaman Phil?).

No petrol tap or filler cap fitted as yet - I have a tap kit & new filler cap to fit.
All the big ticket items purchased just some minor oddments for the final fettle.
