My lift lever on my 51 was getting very hard to use so I decided that I would take the lever off the shaft and lube it. Had to use a puller to get it off and then I see that it had heavy rust further into the cover that I couldn't get to. So I took the seat off and then all the bolts. I pried the cover loose and found out how heavy that thing is. With it upside down on the bench I got the shaft out and cleaned it up. Inspected the piston and cylinder, went into town for new ones. Drained the sump, flushed it out good. Not much sludge. Put a new PTO seal and bushing in too. New relief valve. Getting ready to reassemble now and was wondering how all the little springs and levers under the cover get lubed?Do I give them a good coat of 90wt before I bolt the cover back on? My sticky lever is into me for about $200 so far, but it's good therapy for me! I wanted to take the lift arms off too for a good blasting and paint but they ain't budging.
