Disassembled an over/under tonight and noticed two things that concern me. First, the teeth on the direct drive clutch plates appear to have cut into the gear on the input drive shaft. More so on the inner plates, the innermost plate has cut almost halfway through the spline on the gear. I don"t think this is normal wear and suspect it is due to the direct clutch slipping, even though I never noticed any problems with the o/u before taking the tractor apart. Secondly, I took a look at the output shaft where the sprag clutch rides and found it to be dark in color but very smooth where the rollers ride. The edges seem to have slight wear on the shaft, from the spring clips on the sprag, I suspect. The sprag itself doesn"t look terrible, there is some wear on the inside where it rides the shaft, but the outside is clean and so is the inside of the sun gear shaft it tucks into. Probably going to replace the sprag regardless, but wonder about the output shaft. In this condition, should it be replaced? Took a photo, should be attached.
