SPINDLE INSPECTION :
Spindles are equipped with two ball bearings. Adjustment is set by tightening the
1” NF left hand nut to 60 ft-lbs torque for proper setting.
Periodically inspect blade spindles by grasping pulley, 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 gearbox to mount.
Loosen 1/2” x 3 1/2” tap bolt and slide gearbox toward front until belt becomes
slack and is easy to remove.
Remove belt.
Remove 4 bolts attaching spindle assembly to mower deck 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, it may
be in your best interest, both time and money wise, to use a new spindle assembly.
Remove pulley from spindle assembly. Place the assembly in a press and force
spindle down through housing. Once pressed apart, replace bearings as removal
will have damaged bearings internally.
