1080 MF diagnosis

[challengertn]

I'm looking at buying a 1080 to restore. The motor fires right up, when cold, with little to no smoke. The problems are; the multipower has no response when shifting and there is no engine braking. The pto runs continuously, and the lift is not the fastest I've seen. The clutch releases right at the top of the pedal travel. Other than that it seems like a decent tractor. What will I be looking at, worse case scenario, to repair these problems. I don't plan on using it in anything strenuous, just to restore it. Thanks in advance

Concerning the multi-power: When it is working correctly, there is engine braking only in high multi-power; and never in low multi-power. When multi-power fails, it usually fails to engage high multi-power and is constantly in low multi-power -- thus there is no engine braking. Hope someone else can outline the steps needed to fix your multi-power.

Three point has it's own pump, auxiliary hydraulics and MP/PTO clutch are both fed by a two stage gear pump. Smaller gear set feeds MP/PTO control valves and larger gear set feeds the auxiliary valve. Low pressure MP/PTO side can be checked, auxiliary high side can be checked at the outlets. If pumps require removal the lift cover must come off and tractor split at transmission/diff joint as they come out the front of the diff case. Not a fun job..

heir is an over looked filter in the small round canister next to the oil cooler in front of the radiator. You would be wise to check it before tearing in to the rest of the system.

I know one solution for the multipower is to lock it in to high range permanently. If this tractor has a poor reputation for heavy tillage anyway and I have no plans to even use it for tillage how satisfactory would this be and could it be reversed if someone wanted to?
