That's like my toolbox..Curver?...  But mine has red clips to secure the lid.

I think it's a Curver copy I've had it for a good 40 years.

Update it is a Curver !

Nicely summed up Ken I was thinking Bet Lynch so I've missed the mark a tad.

That petrol is probably knackered by now Ted I'm sure the stuff has a shorter shelf life than that

It's what I use for cleaning engine parts - SUL no expense spared!

I've gone back a bit having stripped down the front forks to sort out a stripped thread on the left leg where the top calliper arm is fitted.

As a result I have found that the fork seal that are 35 x 48 x 11 has moved up on one side towards the circlip - there is what seems a big gap as though there ought to be a spacer between the seal & the circlip. When I fitted the seals they were flush at the bottom what's going on here?

Wonder if it’s bad fitting Ted? Cant see that it would shift touching against stanchion. Assuming they are correct seals for the job.
Maybe an attempt to get worn seals to seal?

I have a vage recollection of early seals being a different thickness from later ones but not sure if it was just 750 or which way. I think there was a service bulletin about it

They were new seals of the correct size for a 500  - they shifted when I was dismantling the forks -there was a substatntial gap 2-3 mm between the circlip in the groove when they were fitted fully down against the shoulder earlier in the year.

Bryan might be onto something about an alternative seal size being fitted.

Sorry Ted, certainly wasn’t suggesting you had fitted badly! Thought maybe there had been a previous hammer wielding monkey at it. 🤣🤣

According to parts book the seal should be 35 x 48 x 11, and from what has already told me that's what's printed on the seal. I do seem to recall some seals having a metal spacing washer fitted under the seal, snug fit inside the slider but bore too big for it to ever touch the stanchion. Maybe that's what this needs. After checking my spare sliders I can confirm the shelf the seal sits on is 14.5mm from bottom of shelf to circlip recess, so if the seal is only 11mm that's a 3.5mm gap allowing the seal to move up and down. Doesn't seem a good idea to allow it to do that.

I agree Ken that is the seal I have 35 x 48 x 11 - the old seal was binned so I can't compare it now but 100% certain there were was no spacer fitted.
