Hi everyone, I have a couple questions about an old 806.
1st problem: About 3 years ago we were stacking hay with a Heston stackhand when the tractor started moving slower and slower till it quit moving. The low side of the T/A had been slipping for years and we assumed the hi side was bad. Pulled it into the "fix it up" tractor line up where it was started regularly to keep the engine from siezing and to see if it would move, never would move. Last week I took off the cab, all the sheet metal, and power washed it for the teardown. I jumped on it a couple days later when the weather was cooperating to pull it into the shop, put it in gear and it wanted to move. Took off the chain and drove it for about 10 min. seemed like it use to be.Then I run it at half throttle for 45 min and it started slipping in the hi side of the T/A when in road gear. Why after 3 years did the T/A decide to lock up after we tried several times? Could there be other problems I am ovarlooking? MCV is adjusted properly, and the MCV pump is operating at the correct pressure. We would be more than happy to replace the T/A if that would fix the problem.
Next problem: The 3 point only raises once in a while. I can make it raise if I put the tractor in gear and let out on the clutch a little. This seems strange to me because I dont think the clutch has anything to do with the 3 point?
Last problem: I cannot get any oil to come out of the the remote valves. If I take the relief valve out of the housing, oil shoots out. The pump worked fine when parked. Could I have a leak between the pump and the relief valve, so it would not build pressure? Or is the pump bad? Could this have something to do with the 3 point not lifting? Im kind of confused! Any help on this would be GREATLY appriceated.
