Hello all. I manage our club’s 235hp Pawnee and am about to dive into servicing its gear shocks. Ours is a non-bungee gear, just has the massive air-oil shocks, one of which appears to be “flat”; it doesn’t move on landing or during taxi. Hopefully it’s just lost its air charge. But just in case...anyone had any experience rebuilding theirs? Haven’t yet found a source for o-rings or seals. Thanks.
