DMC piston check valves - 10/10/18 01:36 PM
I have a telescopic jack on a Thyssen DMC and the pistons will not resync. Ordered new piston check valves but I've yet to perform this task. Any helpful suggestions?

Order seal kits as well. That’s more than likely your problem.

Thanks. We did. The pistons are carrying oil so not sure that is keeping us from synchronizing with zero pressure but I figured if I'm taking it apart I'm not gonna do it twice lol
order the internal seals for the bottom of the pistons. 3 stage tele has 2 internal seals and the 2 stage has 1 internal. Per jack

Make sure you use Gorman packing.
