Transmission High Jack Problem

[widetrackman]

NAPA 700 transmission jack made by Sunnex I think; marked 520-4002 leaks down when loaded. No fluid leaks.Replaced piston seal no change. Removed release valve looked ok, but there was no ball in port, is there supposed to be one that goes before the release stem. Also when leaking down pump lever does not move up if check valve was leaking .I can not figure out what to do next.

Return it?

Return it?

Well I can't, It was given to me. Had been setting up for a long time. Surely its fixable.

Surely its fixable.

only if you can get the parts, and with the lineage - that will be the hard part. You might check a local tractor supply/repair shop to see who and if they can get the parts.

Our local JD and Case will rebuild other makes of cylinders/pistons, if they can get parts.

not sure who they source those parts through.

best of luck

Assume you have contacted NAPA or Sunnex, you might be surprised?

Northern supply sells new jacks for a decent price.
