GARY F Posted January 7, 2012 Share Posted January 7, 2012 this jack worked last summer. now i push down on the handle & the lifting pod goes up. when i lift the handle again the pod goes down. it never stays in the up position. no oil leaks & i cant find a name or model #, any suggestions.

Guest Jim_Edwards Posted January 7, 2012 Share Posted January 7, 2012 Remove the cylinder and take it to a hydraulics shop for a rebuild. Link to comment Share on other sites More sharing options...
Rusty_OToole Posted January 8, 2012 Share Posted January 8, 2012 Try filling it with jack oil. That usually fixes them. Or you have a sticky valve. Link to comment Share on other sites More sharing options...
Guest trainguy Posted January 9, 2012 Share Posted January 9, 2012 Agree,sounds like a stuck check valve.It is a steel ball located between the pump and the cylinder.Most likley located under a plug in the housing.Phil Link to comment Share on other sites More sharing options...
