SPINDLE SERVICE

NOTE: SDR series mowers have been equipped from the factory with two styles of
blade spindles:
Up to SN 13365072 (SDR-65) / SN 13390079 (SDR-90)
Blade spindles are factory equipped with greasable bearings. These spindles are
identified by a grease fitting in the center of the drive pulley. Grease must be added
to these spindles at least every 8 hours of running for a proper service life.
SN 14365073 (SDR-65) / SN 14360080 (SDR-90) and Above
Blade spindles are factory equipped with sealed, maintenance free bearings. These
spindles are identified by the absence of a grease fitting in the center of the drive
pulley (early production & replacement maintenance free spindles have a set-screw
in place of the grease fitting).

SPINDLE INSPECTION

 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

1. Remove blade from spindle.
2. Remove belt shield. Loosen 4 bolts that hold gearbox to mount.
3. Loosen 1/2" x 3 1/2" tap bolts and slide gearbox toward front until belt is
easy to remove.
4. Remove belt.
5. 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 REBUILDING

 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.
