Hello, hopefully I'm I'm the right spot for this.  We have an allis 7060 that we use as a rake tractor, last fall mid 3rd cutting it lost the hydraulics and 3pt mid rakeing. The power shift and steering are both functional still.

Context: I pull an Allen rake (knock off darf). It uses a single hydraulic remote and then the oil is directed to the desired cylinder by an electric valve body mounted on the rake. 
After turning around at the end of a row and getting everything set I usually return the remote to neutral so the hydraulics don't buzz full time, this particular time I forgot to disengage it, so I turned around set the rake down, and made my pass, when I went to re engage the remote I noticed it was still in and went directly for the electric switch, nothing happened. I fiddled  around with it for a minute and concluded I wasn't going to take off and work, so I headed back to the shop and checked the hydraulic oil a d it was lower then I'd like to admit (almost 5 gallons) after filling it the hydraulics still didn't work,    which is when i discovered the 3pt also had stopped.

Needing to get the hay off the ground I finished raking without Hydraulics and the tractor got parked for a "winter" project. Well winter is gone and now it's time to actually fix it.  Any help or suggestions on what could cause this would be much appreciated, I'm about to change the hydraulics filters and go from there. 

Thanks.

Ok, I changed the oil filters and continued trouble shooting from there And determined there was no charge pressure. When I pulled the compensator spring (number 29) it was broken in half. Does anyone know where I can get a new spring? It's for the piston pump on a 7060. Thanks

An AGCO/Allis dealership is the only place and you will possibly need shims to adjust the pressure.

You will probably have to get a complete compensator
Finding that spring for a cesnna pump is iffy im afraid. That design was bought out by eaton. You might get lucky at a really good hydraulic shop. Some of the salvage yards should have a compensator. I hope you can because i priced a compensator a few years ago from agco and it was 800 dollars
