Ford 5000 pto won't engage

Noah Washine · Jun 5, 2022

Hello we have a Ford 5000 I use to cut and bale hay. Yesterday I was testing my new to me tedder to see how it works and I would push the lever to engage the pto back and nothing happens. We put fresh hydraulic oil this past spring so it ain't low. It did this last year but we were able to get it to work. Now it won't engage at all. Idk if something is disconnected ? Thanks in advance.

Pto has hydraulic clutch. Its powered from the dual hydraulic pump on the side of the trans. The low pressure portion of the hydraulic pump powers the pto clutch and the optional dual power clutch. SO... could be worn out low side of hydraulic pump, should be above 120 lbs when in off and when in on position. (Book says 160lbs new). Could be the plastic or metal line that crosses over the trans, from the pump, to the pto valve at the lever. This line can break or crack... Could be the hydraulic valve at the lever that turn on and off the pto circuit. Or could be the pto clutch or support. The support is a sacrificial mount and should be replace anytime you work on the pto clutch as it as sealing rings in it to allow the flow to the pto clutch shaft, and it and the rings/mount wear out badly. the pto clutch can have a bad oring and/or worn clutch plates in the clutch pack. Worn out pumps and plastic line cracks are a bit higher on the list. But a worn pump will usually show the high pressure side 2175 lbs is usually in the 1600 lbs range or even lower after warmup. SO the 3pt lift would be very weak as well.

First thing I would look at is the little little nylon line from the pump to the clutch. They are famous for breaking. You will need to lift
the top cover to access it. We used to remove the top cover, and tap the hole that supplies oil to the three point arms. Crank the engine
with the fuel stop pulled(or coil wire pulled for a gas engine)crank the engine, when oil comes up, swipe the tap filings away with a rag to
get them out of the system. We would then screw a fitting into the hole with a copper line aimed back into the sump, then you can start the
tractor, engage the pto, and look for leakage, and see what is functioning. They are also known for the clutch piston cracking. By the way,
look out for the hidden bolt under the right side lift arm shaft!!!
