Hello! here's the situation... I unintentionally won an action on a CaseIH 4210 with a 2255 loader. 16spd shuttle (power?) shift. MWFD No Cab. Tractor has 3500 hours. It has a single hydraulic leak on the loader itself and then one on a line that runs from the hydraulic control valve back and under the tractor. I have no owners manual or Service manual but plan to find them either online or hardcopies.
Tractor fires right up. Drives forward in all gears just fine. but the loader is slow to respond and the tractor will only reverse on perfectly level ground (or down a hill), if there is any sort of pressure against the tractor forget about it. Also to me, without a frame of reference except for a much smaller tractor, it seems like the hydraulic pump is extremely noisey, and it changes pitches when i am in forward vs reverse, cycling the loader, etc. My other tractor is just a little geared tractor, so generally there is mechanical noise and feedback when something isnt right.
Things I have done so far include: Fresh hydraulic oil and filter (when i did this the filter and screen had large chucks of what felt like cardboard gasket material on them - so any ideas on what that would have been would be appreciated), wrapped the couple of leaks with self healing tape to try and just see if there was enough system leak to drop the pressure low enough to not operate any clutches properly and made sure the main clutch was good (Put the tractor in it's highest with the brakes on, and let go of the clutch bogged it and killed it instantly, zero slippage).
I plan to replace the lines that have leaks and replace the hydraulic pump (as well as the filter and oil again, as I plan to this this batch as a sacrificial flush) but what else should I be looking for?
Any and all help would be greatly appreciated
thank you!
