SPINDLE SERVICE PROCEDURE (Cont’d)

Coat the outside of the seal with silicone and install the lower bearing, seal, and retaining ring into the
housing, using the correct seal installer.

Place a light film of silicon or permatex on the inside diameter of the bearing ring and seat the ring on the
spindle shaft, using the proper tool and press.

Lightly lubricate the lip of the seal.

Using the 2-3/4" tubing to prevent the cup and cone from contacting each other, press the spindle shaft
through the lower bearing and seal. Make sure the bearing is seated against the bearing ring.

Place loctite on threads of the bearing adjusting nut (flange nut).

Using gloves, install the heated upper bearing cone on the shaft immediately and push it all the way
against the cup. Lubricate the bearing with LPS.

Install the bearing adjusting nut. Tighten the nut until the spindle shaft can not be turned. Loosen the nut
1/4 turn. Place a soft, clean cloth over the top of the spindle assembly. Place an aluminum block over the
end of the spindle shaft and strike the block with a hammer to loosen the bearing.

Remove the cloth, being careful not to allow any contamination into the spindle. Tighten the nut until a
rolling torque of 16-21 inch-pounds is reached. (If the seal was not lubricated, add 10 inch-pounds).

Stake the nut with a blunt, round nosed punch. Do not tear the nut.

10. Insert the lubricant nozzle into the hole in the center of the housing (between the bearings) and fill the

housing with 000 grease (P/N 00765444), stopping when the lubricant covers the upper bearing
(approximately 11 oz.).

11. Install the breather plug in the top hole (if there is a top hole), and the solid plug in the fill hole. If only one

hole exists, put the breather plug in it.

12. Install spindle in mower deck and assemble in reverse order. Torque the blade bar or pan bolts to

400 ft.-lbs. Torque motor to spindle bolts to 85 ft.-lbs. Torque spindle to deck bolts at 175 ft.-lbs.
