Hi all, the PTO pump for my wet line on my mack road tractor is acting up. When i engage it in the cab, the line will get pressure for a few seconds (maybe 15) then the pressure goes away. I don’t hear it jumping out of gear, i don’t hear any grinding. Is the pump just worn out and passing by? any ideas?
There is an Oring on the relief valve cartridge. Pull the whole cartridge, and you'll probably find the Oring damaged. #31
I'd like a little more info: Single line or two line wet kit? Transmission? How does the wet kit engage? Electrical, air or manual/cable lever?
2 line. it’s bolted onto an eaton 10 speed in a mack cxu. air engaged.
