    i bought an old municipal truck off here . its an 1982 l9000 with a pto on the front. im not getting any pressure. have it engaged and still nothing. the pto runs the spreader in the back. is the pump burned up? if so is much to rebuild one. thanks kirk

    pto

    better have a truck equipment shop put a pressure tester and flow gage on it first after you check out the obvious oil level, in line filters etc ,plus you better know what kind of pump and pto you have first .or straight crank drive load senseing hydraulic's .

    I know this sounds stupid, but are all the taps on and is the oil tank full. Check your hydraulic filter and can you move the spinner by hand or the chain with a pipe wrench, just want to make sure nothings seized. I read when that truck was for sale it needed a new oil tank, maybe it was changed or I'm thinking of another truck. Are one truck I thought the pump was gone and some buddy turned the main valve off, so the pump wasn't getting any oil. Take the inlet off the pump and see if the oil free flows into a pail when the trucks not running. Pumps will last forever unless they are run dry.

    i ended up driving it back to kc myself. i had a driver but he drove it one exit and wimped out. so i said what the heck. yes this is the truck off here with no tank on it i took off an inspection plate on the pto and it looked fine. but im new to the hydro part of this truck.when you say oil do you mean in the hydro tank itself?

    So did you get it running? What did you have to do? I'm not an expert but we've built a couple of salt trucks and stuff for the farm.

    We use just universal hydraulic oil in our trucks. You should have lots of flow with a front pump. Is there a filter, does your spinner at least turn? It could be the pump with very little flow, who knows what happened before you got it. I'm not as good at explaining how to fix it, as I am doing it myself.

    The filter would be a good place to start!
