Howdy bus folk
I use 12 ton bottle jacks for my buses, and recently one would only go up about half way, (although it did fine up to that point), then just stopped about halfway through normal travel.
Any ides how to get these critters back to work? I noticed it has a small rubber plug about 2/3 the way up the body, and I assume that is for refill, but the jack shows no sign of leakage; and I'm also scared that if I pull out the plug, it may not seal after that.
Any and All help appreciated.

Chinese?
I have one (yes Chinese) that does go full up, but slowly leaks back down. Sure was nice when we had US products that had US folks to fix them, but those US ones sure were expensive.
Plug on mine is just for oil filling. If I loose too much oil it won't go full up, so I open the plug, fill and it works. |

Hi Pat & Folks:
As the quality of jacks has declined, several years ago I settled on Craftsman (from Sears) US MADE, heavy duty jacks. We are getting excellent service from them, and they are used every day, all day long. One word of caution, always keep a jack upright as laying them on their side will cause oil internally to leak past seals and mess them up.
I Hope this HELPS!!!
Happy & SAFE!!! Bussin' to ALL.

I have never had any trouble with oil leaking internally. Not saying it can't. Push the piston all the way down and then fill it with oil thru the hole that the plug is in. That is what it is for. Use 10 wt. oil AT fluid or trans fluid. It will all work. |

One thing to check is make sure the bleed hole is open. Usually it's built into the full plug but not always.
If this isn't open then it will pull a vacuum in the reservoir and act similar to as you describe.
Good luck,

Ooh rats!
I keep a lighter one on its side in a tool box in the truck for the box trailer, etc.
Thanks Luke, I'll figure out a different way to store it. You're a smarter guy than me!
Thank you.
happy coaching!

Could you provide a bit more detail about the bleed hole? Where are the spots it can be found?
Thanks

Patrick,
I can't say exactly where it would be on your jack but most of them are built into the fill cap. Try loosening the fill cap and see if the jack works properly.
I'd be curious if this helps.
Good luck,
