My low-buck Chinese hoist has been leaking hydraulic fluid out of the cylinders for some time and it's time to fix it. After some internet searching I found a place called <carliftparts.com> and they sorted out that it's a generic Chinese hoist as Pace Tools is evidently no longer in business (at least I couldn't find them). It's the same as a Tuxedo and several other brands. What identifies it is the chain lift mechanism which shows in the following pics. Carliftparts had the seal kits and for less than $100 shpped to me I figured it was worth giving it a go myself. There's an online video that shows how to get the cylinders out and I basically followed their method.
If you drop the carriage and pull on the chains to fully compress the cylinders the chains can be set aside as seen here.
Then pulled out of the way.
The hydraulic connection penetrated the hoist frame and so must be disconnected. Remove the line.....
Then remove the fitting that goes into the cylinder body. Note the spring that goes back in.
Being not a gorilla I brought in some hydraulic grunt to take the cylinder out
Cylinder in the vice and here I'm screwing the top retained off.
A look down the bore which was a happy surprise - I was expecting gouges or rust of some such - it seems OK. It's a bit mucky at the bottom of the bore but I'll clean that up tomorrow.
The seal package on the ram.
And the new bits with the ram
Back on this tomorrow.
