hydraulic system jerking when cold on 245 Leyland
HI,
I have a 245 leyland with a front loader. Last year I changed all hydraulic fluids and new filters (high and low pressure) including removing the tombstone and cleaning the metal filter box and the round one on the drain plug under the differential. During the summer the hydraulic system operates great, however now it is getting colder. (50 degrees F) and the hydraulic system is jumping when cold. It clears up once the tractor warms up a bit. The jumping happens in both the loader and the three point lift. I would say it acts like there is air in the system. I have checked the oil level and it is fine.
Has anyone had a issue like this before and found a solution?
Thanks Joe

Re: hydraulic system jerking when cold on 245 Leyland
hi check your pto clutch is fully released . put the pto in gear and watch it when the oil is cold if it momentarily stops n starts it might be the pto clutch slipping this is usually more obvious if you labour the hyds ie crowd your bucket right back and keep the lever pulled to load the hyd pump . if the pto is stopping and starting check the levers under the floor are fully forwards to fully release the clutch .

What kind of oil do you use in the gearbox?

I will try the PTO clutch tonight and see if that is the problem. I have been using a post hole digger with no problems so It may not be an issue or the hydraulics my place more of a strain on the clutch than the digger.

when you changed the oil was it white and emusified ive known this emulsion leave behind little droplets stuck on the transmission sides and when new oil was put in it loosened this stuff and it all ended up stuck in the filter and it had to be cleaned again .

Hi, That is a hydraulic oil and while the viscosity is about right it wont have the correct gear oil properties!okiejoe wrote: ↑Wed Nov 06, 2019 6:48 pmHI,
