No hydraulics

Postby NTFYNM » Tue Jan 21, 2020 1:04 pm

Went out this morning about 19F outside. Tractor started and I let it warm up for 30 mins. Went back outside and hydraulic pump was whining and I had no hydraulic power on the FEL. The dipstick read full. Any ideas where to start?

We have had a lot of calls lately where water in the oil turns to ice and clogs things up. What model tractor do you have? Have you cleaned your internal screen lately?

If there is any water in your oil it will freeze and collect on the screen.

I can tell you there is a tom of water. As soon as the oil was changed it was milky. I went through 10 gallons of oil and it was still milky so I gave up.

Milky looking oil can also be caused by aeration. Both can cause the problem you described.

Ok so I put a block heater on the tranny and checked the oil. It is now about 2 inches above the full line.... How can this happen?

Sounds like rain or snow water. Shifter boot, broken vents on axle housings, etc.

I will check the boot. Not sure where the vents are. Seems like an entire fluid change as well. What type hydraulic fluid/ tranny fluid should I use.

I use the Tractor Supply brand, have used it in a geared transmission and have been using it in a hydrostatic for several years. Worked great for me. https://www.tractorsupply.com/tsc/produ ... yZEALw_wcB

Changed hydraulic oil and cleaned screen. Hydraulics last longer but still stop working after 30 mins... any ideas now?

what did your screen look like when you cleaned it? covered in crud or not bad? Are you confident you are not sucking air in your pump?
