My old, tired 640 is still an amazing machine. I was doing some bush hogging yesterday when I noticed my right boot was getting covered with a fluid. I climbed down and looked at the hydraulic pump (ball bearing piston type). A fine stream of hydraulic fluid was coming out at the first seam behind the cover at about the 1 o'clock position. I tried tightening the bolts securing the cover - got about 1/8 to 1/4 turn on each but the stream was still flowing. I am hoping a gasket set will fix the problem. My question is, can I replace the gaskets behind the cover and plate without totally disassembling the pump as called for in the overhaul manual? I am hoping I can remove the pump, put in a vice with the cover facing up and remove the cover without losing the pump components or otherwise messing things up. I know I should take the opportunity to do things right but I am trying to help our small church clear our new 18 acre property on a rather tight time line and very small budget. My time, talent and tractor are free which leaves the money for other expenses.
Thanks
