Rebuilt my forks. New all balls seals in, new hyperpro fork oil and springs.
If you want to know what the inside of your fork looks like, here you go
On the left side, from the bottom up you have:
bolt at the bottom that attaches to the damper rod
cup which the damper rod sits in
damper rod
rebound spring
main spring
washer
spacer
and the then the cap.
In the middle, that's on the outside of the inner tube, inside the outer leg:
bush (already on the bottom of the fork inner
second bush that sits in the top of the fork leg under the seal
washer
seal
clip
new hyperpro spring on top, old spring on the bottom
The new fork seals are proper tight, like a....
Makes you realise just how loose and sloppy the old seals are.
Just did a quick test ride and she's niiiiice
Seems a lot smoother, no crashing over bumps and less dive when braking. And of course, no oil all over the fork leg.
Didn't take that long to reassemble, overall not that hard a job TBH. I gave the inner tubes a clean with a scourer, took all the rust off. And hanging the lower legs overnight worked a treat, they were sparkly and clean in the morning.
