Drives and runs fine. After a few hours,rpm is good, but does not translate to power to drive train. It will operate in4 wheel drive) Pulled primary and secondary. cleaned, checked belt(only a fewhours). tested the wet clutch by turning to left, spins freely, turns to rt andlocks (it is suppose to). If it was belt, primary,secondary, the problem wouldbe constant. Will the wet clutch ck out as ok on a cold test, but still be theproblem when it gets warm? Running synthetic oil.
