Anyone know what the torque specs or gear backlash should be on the gearbox on the mower deck. I'm rebuilding the box on my 831012 48" deck. I have the original manual for the deck but it only gives a parts breakdown and instructions on setting level and replacing the belt. I need to know the torque for the nut on the output shaft and setting for gear lash.

Answered my own question. Found all the info in the attachment section of the repair manual for the tractor.

Torque on the nut on output shaft inside the gearbox is 50 ft.lbs. Spindle nut holding blade and pulley on is 50-60ft.lbs. End play on output shaft should be .003-.008in with DRY bearings. Backlash for gears is .005-.015in.  End play on input shaft is .003-.008in as well.
