A person could purchase a pto pump from several different places. Some of the places that one can purchase a pto pump from are: Northern Tool, and eBay.
Same as you do on a manual transmission... you drain the transmission fluid, remove the PTO cover, and install the hydraulic pump or motor where the PTO cover was.
PTO is Power Take Off... if the truck has a hydraulic system (such as dump trucks, wreckers, roll-offs, etc.), then it has a PTO which engages the hydraulic pump.
To transfer power from the PTO or ETO (a PTO mounts to the transmission and is driven by the flywheel; an ETO runs off the engine crankshaft) usually to a hydraulic pump.
To diagnose PTO pump hydraulic problems, first check for any visible leaks or signs of damage in the hydraulic lines and connections. Next, ensure that the PTO is properly engaged and that the hydraulic fluid levels are adequate and free of contamination. You can then test the pump's output pressure using a pressure gauge; inadequate pressure may indicate internal wear or blockage. Additionally, inspect the hydraulic filter for clogs and listen for unusual noises from the pump, which could signal mechanical issues.

PTO is a Power Take Off. It's often used to operate hydraulic systems (e.g., the hydraulic pump on a dump truck).
Depending on which end it's coming from, you probably have either a leaking tailshaft at the PTO gearbox, or a leaking input shaft seal on the hydraulic pump.
Farm tractors and some trucks and industrial engines can have a PTO or Power-Take-Off shaft that is used to power attachments such as sprayers, hydraulic pumps and, well, generators. The PTO is low speed, so a PTO generator usually has a gearbox to step the speed up to the RPM needed to turn a generator. PTO's are pretty standardized and use a short driveshaft to couple the tractors PTO to the attachment. PTO generators are used where remote power is needed and a PTO-equipped vehicle is available. It saves having to buy and maintain another engine.
You will probably burn out the hydraulic pump in a short time.
If it only shuts off when the PTO is engaged it could be the field coil on the PTO is drawing too much current and activating the self resetting Circuit Breaker attached to the starter solenoid. This happened to me on our 316. If the PTO is shutting off it could be a bad connection on the field coil wire.
The 185 had a live PTO in that the tractor's movement could be stopped with the PTO remaining engaged through the powerdirector clutch (this was the tractor's 2 speed, shift on the go, set up). However, if you pushed the foot clutch in, the PTO would lose power along with the forward motion of the tractor stopping. Also, the 185 was available with a hydraulically engaged PTO clutch, which would allow the PTO to be engaged while the tractor is moving, where the mechanically engaged PTO required the foot clutch be depressed, the tractor be brought to a stop, then the PTO engaged and the foot clutch reengaged. It was "live" per definition, but not "independent."
As engine rpm increases so does pto speeed And if you tach your motor to an excessive amount of RPMs while the PTO is engaged, it will destroy that PTO, leading to zero PTO RPMs.
