I seem to go through O-rings way too quickly.
I usually get about a week out of a set of
O-rings before my shocks are leaking again.
How do I make them last?
First things first: Make sure you’re not overfilling the shocks with oil. With the shock springs
removed, you should be able to compress the
shock shaft all the way into the body with
consistent pressure throughout the stroke. If
you have to force it, there’s too much oil in the
shock. After a few hard hits, that pressure will
blow oil past the seals. Let’s assume that’s not
the problem. How are those shock shafts? If
your nice new seals are paired with scu;ed or
scratched shock shafts, the shafts will quickly
wear the seals and oil will weep out of the
shocks. If the shafts aren’t smooth and shiny,
replace them. And finally, make sure you’re
coating the seals and any parts they touch in
seal grease (best) or shock oil (OK) during
assembly. Don’t put the shocks together “dry”
or you may shorten seal life.
Lube the seals before installing them in the shock bodies. Use seal
grease if you have it; if not, use shock oil. Never assemble seals and
related parts “dry.”
Seals need a perfectly smooth surface to
seal against. If your shafts are thrashed
(like the one on the left), your shocks
will leak even with new seals.
