SPINDLE SERVICE
Spindles are equipped with two roller ball bearings. Adjustment is set by
tightening the 1” left hand nut to 60 ft-lbs. torque for proper setting.
Periodically inspect blade spindles by grasping blade, and moving from side to
side. If any free play is noted, replace or repair.
SPINDLE ASSEMBLY REMOVAL
Remove blade from spindle.
Remove belt shield. Loosen 4 bolts that hold gear box to mount. Loosen ½ x 3
½” tap bolts and slide gear box toward front until belt is easy to remove.
Remove belt.
Remove 4 bolts attaching spindle assembly to mower frame and remove as a unit,
since pulley will come out through the hole in the deck.
SPINDLE ASSEMBLY INSTALLATION
Reverse above procedure. Be sure spindle mounting area of deck is clean of any
foreign material before attaching spindle assembly.
SPINDLE REPAIR
Spindle repair requires special skills and tools. If your shop is not properly
equipped or your mechanics are not properly trained in this type of repair, you
may be time and money ahead to use a new spindle assembly.
Remove pulley from spindle assembly. Place assembly in press and force spindle
down through housing. Once pressed apart, replace bearings, as removal will
have damaged bearings internally.
