So my rear left boot opening ram leaks a little and needs sorting.
I just read the entire 18 page thread on repairing the cylinders, that thread is not open for reply’s though and I had a couple of questions.
There are still “kits’ available on Amazon which show images of 5 o-rings, 2 are larger. This has me wondering as I thought ALL 5 piston seals are the same size, specifically the 15 x 5 x 22 u cups.They obviously don’t mention sizing so they can sell a few 50c o-rings for $30US plus $25 postage. Is the picture correct or a red herring ?
I was considering trying to get u cups instead of o rings but can only find 16 x 5 x 22 here in oz and I think lack of posts here lately about leaking pistons lends me to believe that the o ring solution works just fine even long term. Given it appears somebody stuffed up and the original seal material and hydraulic fluid were incompatible, I would imagine a non leaking o ring is a long term solution as it doesn’t deteriorate
So I am wondering if anyone has experienced leaks with the o rings ? Are they all the same ?
Some people reckon the "correct" o-ring is 15 x 4.5 but others say the 15 x 5 works fine. I can get either. Looking at the u cup dimensions then (22-15)/2 = 3.5mm is the actual rod to cylinder clearance. So 4.5 or 5mm, or some other size like 4.8mm ? I’ll probably buy a few sizes anyway and spares given they are like 50c each.
another advantage of o rings is it looks like in at least a few instances the o ring can be stretched over the piston without removing the clevis from the ram, though the rams I want to do first have a lock nut anyway and should be simple enough.
I will probably tackle the 2 rear cylinders first and the latch cylinder as I currently have the boot lining and headliner off.
