1085 powershift

Alf Roberts · Mar 20, 2019

Hey Guys, low pressure hydraulics question 1085 with cab. If I put a gauge on the pto port at idle and turn the pto on and off, pressure is 250 psi one way and 0 the other. If I move the gauge to the powershift port (right hand side of the firewall) at idle I get 225 psi in low and 125 psi in high. If I rev it up I get 250 in low and 225 in high. (this is with fairly cold oil)In the summer the powershift has only been working in low, or sometimes very weakly in high.

1) Is the pressure supposed to drop to near 0 when the shifter is in high?

2) Any ideas on what is wrong?

3) Is there a troubleshooting flowchart, hydraulic diagram, youtube, or website that anyone knows of. I have an owners manual, parts manual, and a I&T shop manual but it gives disassembly procedures but not diagnostics.

Thanks
Alf

Does that have anything to do with the design? We had a 1085 years ago and I remember there was no engine breaking in one of the positions which I think was in low?
