Searched the forum til my eyes crossed..I have an NAA, total rebuild and hyd pump went out. Ok no big if I can rebuild a tractor whats a pump? Ordered a new kit from Stevens 1st mistake tore it all down cleaned everything and reassembled I had extra washers O-rings who knows what, I replaced the bearing and race on the eccentric shaft (that won't happen again) ordered the new needle bearing for said shaft I thought I'd covered it all. Reinstalled took upper plug out primed pump, cranked tractor checked plug again no oil movement. Ok I thought check fluid level it was fine. Nothing seems to help what have I missed or omitted? Is there a manual or anything that covers just this piston pump?

Might try priming it by applying compressed air to hydraulic dip stick hole.

What were symptoms that made you believe the pump failed, and are they the same now?

The symptoms on the bad pump were made mistake and tried to pick up a rolled hay bale with the old girl, blew seal out and oil shot everywhere rebuilt pump and now nothing. Haven't been out today to see about pressurizing the dipstick tube we gat a cold snap it's 35degrees today for south Alabama that's cold. Just wanted to check with everyone like I said totally rebuilt the old girl and we use her mainly bush hogging guess need to semi retire her and get some thing with a live pto system. That pump is very costly and I have seen 2 different type I think one was a Dextra and the other a piston pump everyone here says piston is the better one.. Still trying to find something on the pump alone (manual book) the NAA book isn't very good doesn't cover very well
