Apart from sealing rings on bolts, gasket ring on the valve was damaged.

To install piston with guide ring is not easy, ring is too loose.
Hayness recommends to fabricate a guide, so i took a brass foil, hard enough.

Soooo, just curious:


My recollection is you are ON the lsle of Cyprus correct?  So do they have Harbor Freight there? (Maybe that's not a HF branded lift? (Very nice btw!)  Or, maybe you bop around the world and these black Friday pics are in the USA?

Huh, i thought i am alone here  :laughing4-giggles:

We do not have Harbour Freight here, AFAIK.
I took it from the local bikers shop. It is not a HF branded lift.

Judging from the size, my first guess is that it came out of one of the fork tubes.

my thoughts were same.
on photo all parts from one fork, there is no this snap ring.


I opened another fork, which has extra parts, and regretfully also did not find suitable place for possible missing snapring. Also did not find it on the drawing of the forks. Required snap ring is installed.

no, wrong type. And if not installed - will not hold springs inside.

I spose you already checked this, but I'd be looking to see if both forks are identical.
