REMOVE AND REINSTALL. To remove the front axle from four wheel drive models, first block rear wheels. Loosen the drive shaft cover clamps, remove retaining screws, then move drive shaft cover out of the way. Detach drive shaft from front axle drive pinion. On all models except YM135D and YM155D models, be careful not to lose the steel balls from drive shaft collars. On all models, detach drag link from steering arm. Support weight of tractor by attaching overhead hoist to front weight support, then remove both front wheels. Place a jack under center of front axle to support axle securely when attaching screws are removed

(with grease, then install with center tooth in center valley of ball nut. Position adjustment screw (15) and shim (18) in end of shaft and gasket (20) on housing, then install cover (16). Turn adjusting screw (15) out through cover (16) while installing, then tighten the cover attaching screws to 23-30 N-m (16.96-22.13 ft.-lbs.) torque. Be sure that adjusting screw (15) remains loose while tightening the cover attaching screws. Install steering arm (24) over shaft splines with index marks aligned. Some models have a missing spline to assist alignment of steering arm. Adjust screw (15) to provide 30-50 mm (1 3/16-2 in.) free pla
