Working on front mount 60 in. mower deck (mounted on F915

Customer Question

Working on front mount 60 in. mower deck (mounted on F915 tractor). Need gearbox set up specs. (bearing preload and gear engagement backlash). This is the later model deck that uses the universal output shaft part no. M88081. This gearbox drives only a pulley. All 3 spindles are then driven separately with the serpentine belt. I have an F1145 tech manual (Sept 1996) that is apparently too old and only shows a 72" deck that uses a crush washer and high torque to preload the bearings.
