Greg_G, yes you are correct. The TM has one hydraulic pump dedicated to steering, the other is for TPH and loader. The operators manual suggests that all the reservoirs of the power train be drained after the 50 hour initial break-in period. I was just at 50 hours when the hose broke on the front loader. Excuse me for being so dumb, but are the powertrain and hydraulics part of the same system?
If so, then (per the operators manual) after the lubricants have been drained off next would be to replace the axle and transmission lube with clean diesel fuel, then jack up one of the rear and front wheels (4-wheel drive) and run the tractor for 2 minutes in first gear with partial throttle. Also operate the hydraulic lift system several times, stop the engine, drain off the washing oil while still hot, and fill axels and tranmission with new lube oil of proper type and grade. Does this make sense???
Thanks a lot for your help. Also wanted to thank the other gentlemen for their tips on the Hydraulic fittings.
