I picked up a JD X300 with a Tuff Torq K46BC that was losing power, determined the cylinder pump blocks were worn. I had a spare K46BT that was supposedly running strong when one axle broke.
I swapped the two cylinder blocks from the 46BT with the broken shaft to the 46BC on the X300.
My plan was originally to just swap the broken axle and use the 46BT but the splined shaft for the fan and pulley was a different size so the cylinder blocks had to be removed anyway to swap the shaft.
Anyway, got it all buttoned up and tested it. Forward pedal now makes it go backwards and the reverse pedal now makes it go forward. What in the heck did I do wrong!?!?! Good news is, it will fly in reverse! It runs great and strong with no whining. It just goes the wrong direction. If I didn't know that I was going to have to pull the tranny and open it back up again I could laugh about this. I suppose I could just mount the seat onto the hood....
