Blade Spindle Service

Removing Spindle Housing Assembly

1.Lower the cutting unit, shut the engine off and engage the parking brake.

2.Remove deck covers from top of cutting unit. Release belt tension. Remove belt from spindle to be serviced.

3.Start the engine and raise the cutting unit. Turn the engine OFF and remove the key from the key switch. Block up the cutting unit so it cannot fall accidentally.

4.Remove blade screw, flat washer, anti–scalp cup and blade from spindle assembly.

5.Remove flange nuts and carriage bolts securing spindle housing to deck. Slide spindle housing assem­ bly out the bottom of the cutting unit.

Disassembly

1.Remove lock nut retaining the spindle pulley on spindle shaft. Slide pulley off of shaft.

2.Press the spindle shaft out of the spindle housing using an arbor press. The bearing spacer remains on the spindle shaft as the shaft is being removed.

3.Remove seals from spindle housing.

4.Allow the bearings and small thick spacer to fall out of the spindle housing.

5.Using a punch and hammer, drive both of the bearing cups out of the spindle housing. Also drive the large spacer out of the housing.

6.A large snap ring is still inside the spindle housing and it should remain there because it cannot be easily removed.

IMPORTANT: If new bearings will be installed into a used spindle housing that has the original snap ring installed, discard the large snap ring that came with the bearings because it is not needed. However, new bearings with their matched spacer and snap ring must always be installed when the spindle housing is being replaced. Replacement bearings are sold only with a matched snap ring and spacer set. These parts cannot be purchased separately.
