Is the reverse pedal pushing the reverse lever? I had to extend my reverse pedal to make it longer, so it would catch reverse. Have moved moved the reverse lever on the transmission, manually to see if it will go in reverse?
If moving the external lever does nothing, then you have internal problems with the pump section.
I added a piece to the pedal.
Teardown and examine! The pump has swash plate that moves in one direction fr forward, and opposite for reverse. Seems like the swash plate is not going to reverse.?
Swash plate is the piece that the pump pistons mount in, and it changes the angle of the pistons , to change direction. # ***** in the breakdown of the transmission. See link below.
