engine hoist problem

I lifted a block with the engine hoist and it will not lower. It is stuck on the "up" position with the block on it. I turn the lowering valve and it comes all the way out but will not lower. Please help. -Ben

The first thing you do is screw that valve ALL of the way back in then start over. Open the valve about a quarter turn then tap the cylinder adjacent to the valve with a hammer. Tap, not whang it - most of those cylinder ends are castings - China, ya know. It might be as simple as a piece of dirt holding the fluid relief. If that doesn't work, then you may have to build a cribbing under the lift arm, then jack that arm up with a bottle jack just enough to take the pressure off of the cylinder. You can then pull the valve off, clean things up then reinstall and try again. Also, if you have the lift arm way out and have overloaded it, you may be able to twist the ram - remember, you have the load off - and that may be enough to loosen things. Or you may have to take everything apart, clean and refill with hydraulic oil since you have it cribbed up and maybe replace the valve. Not fun, a PITA, but that suspended engine ......... it needs to come down.

Oh and welcome aboard

From a safety standpoint, it might be a good idea to get another engine picker in there to get the weight off that bad hoist, if the tapping method doesn't work. It may well be stuck, but it might need to get the pressure off the arm to get it to free up.
If you do get it to free up, and lower, I'd consider draining all the hydraulic fluid, and replacing it before using it again.

Yes. I bought one and it is great.. A few weeks ago the local store marked them down to less than fifty bucks.. I bought two more and converted a couple other tools over
