Spindle Assembly
lO.Apply a thin coat of lubricant to bottom seal (2) and install with spring up toward center of housing.
11*Place bottom seal,squarely on housing. Select a piece of pipe or tubing with an OD that will set on outside edge of seal. A tube that is too small will bow seal cage.
12Carefully press seal into housing, preventing distortion to ‘metal seal cage. Seal should seat firmly and squarely against machined shoulder in housing.
13.Make sure seal lip did not roll under. Distortion to seal cage or damage to seal lip will cause seal.to leak. Damaged seals must be replaced.
14.Apply a thin coat of lubricant to top seal (2) and install with spring up away from center of housing. Top seal should be flush with top of housing.
15Lubricate spindle with a lithium grease of #2 consistency with a MOLY (molybdenum disul- fide) additive. Vent top seal with a blunt edged tool such as a letter opener while filling with grease. Rotate housing on spindle shaft, checking for free movement.
Blade Spindle Installation
1.Insert spindle through bottom of mower deck and install three mounting bolts, Be sure to position grease fittings toward lubrication access areas. Refer to lubrication chart.
IPullev installation seauence is very important fof bearing life. Follow the sequence exactly.
2.Install pulley and split taper bushing with inte- gral key on spindle shaft. Install bolt and flat washer in top of spindle shaft. Torque this bolt to 1.7 kg/cm (12 ft/lbs), then alternately tighten split taper bushing bolts to 1.7 kg/cm (12 ft/lbs).
