Last year I picked up an old Hein Werner model 54. Seals were shot, it'd been sitting outside a while. I ordered a seal repair kit from Lazzar's and started taking the thing apart today. I've never taken a hydraulic cylinder apart before but figured.. why not. It was cheap and they're kickass jacks.
I found 2 things out about it that are giving me pause.
1. I don't have a spanner wrench to take the cap off the cylinder with.
2. I found some pitting on the ram.
Okay, 3 things... 3. The pdf I downloaded with the exploded diagram shows a big nut on the end, not the smooth cap that requires a fancy spanner.
I haven't looked for the wrench yet but I'm sure there's one out there. But I think the pitting is a bad sign. Not sure that there's a seal in the end cap for the pitting to ruin but if there's pitting on the ram then there's probably some in the bore too. and I am sure there's a seal on the other end that would be ruined.
Had high hopes for this rehab... I don't know a lot about hydraulics. Would honing the bore fix it up if it's as pitted as the ram is? Seems like, best case, it would be a slow leaker.
Already have $50 invested in the seal kit. More money chasing down a spanner? HOPE the bore isn't toast? ... or try to return/resell the seal kit and chunk the jack? OR.... try to adapt a bottle jack in place of the factory hydraulics?
