How to fix a hoist

Are their re-build kits for the cylinder? I get nothing when I pump, not low on fluid. Can any idiot fix these?

 

if its an engine hoist i would check with the manufacturer

 

Cylinders are cheap enough to purchase and replace as needed.

 

Take it apart and get seals from your local hydraulic shop. Cheap way to go.

 

Some of the 3 & 5 ton long ram units are all welded construction, no rebuild. And as cheap as they now are, it is easier to replace one.

.

 

Hydraulic seals are standardized.
If you can get it apart, any decent local hydraulics
supplier can match up what you need.
Shouldn't be expensive.

 

Thanks, I had borrowed it and can't give it back broke.

 

I wish people I loaned stuff to followed that rule.

 

I second that . I wish they would just bring it back .

 

Take out the "bleed valve" or whatever you call it. The valve you open and close to raise and lower. On one that I have,(transmission hoist), it got some trash in the valve/spring mechanism, and would"byp***" when you pumped it with the valve closed.
Take it apart, and look for debris, keep the parts in sequence, and you may need a SMALL diameter magnet to "fish" around down in the bleed valve bore.

You got nothing to lose, and it's a damn sight cheaper than a new cylinder!.............You will spill a little oil.

 

so it worked when you got it and then just like that it stoped?, do you think you may have over loaded it?, how long ago did you borrow it? could be a check valve stuck.

 

I'd replace the cylinder. You don't want to mess around with it and give it back to your buddy only to have it brake on him. It could even hurt him and you don't and to hurt a buddy who will lend you his tools . Besides, think how pleased he'll be when he sees it come back through his door in better shape than when it went out. I'd take the opportunity to put a pneumatic cylinder and foot control on it. That's what I'll do to mine when the cylinder ****s out.

 

I bought a cylinder for mine last year, $40. it has a different stroke, takes more pumps to move it up and down, but it bleeds down slower so thats a bonus. My dad left a 409 hanging on it for a few months, yeah thanks.

I always make a point of taking tools back in good shape, timely return and a good cleaning, filling the gas if it needs it goes a long way.
I borrowed a backhoe from my uncle this fall, split a few hydraulic hoses so I had Napa make all new ones, changed the fuel filters cause they were clogged, put a new muffler on it, the old one fell off, filled the tank with fuel. I spent quite a bit on it but I couldnt have done the work I needed without it.

 

I'll give it a try, used it on a 350. Trial fit then install ,not much load.It was weak when I first used it. It sat in his shop for a couple years then a couple months here. It's no big deal< I'll fix it one way or another.

 

they discuss lifts on the garage journal all the time, their a part of the atomic industry.
