The right side fork gives up oil. Like to replace the oil seal & dust ring.

The dimensions are not given in the manual.

Does anybody know, please?

PS Few weeks ago I put fresh oil in the tubes.

Before that I had a hard time to get the rusty stoppers out on top.

Forced them down with a bamboo rod and hammer just enough to free the clip. Hardly moved......

.....UNTIL next morning.... When I loosened the upper telescope clamps the stoppers rocketed into the air LOL

I learned my lesson as there is no such advice in the manual

Can't help you with the sizes, but launching the cap into the air was exactly the same way trick I did. Another way to get at those caps is to use a 2 prong gear puller gear puller

attach to the top tree, push the cap down and there you have a extra set of hands getting that circlip out.
