ASSEMBLY

Tools needed:

Hand tools Hydraulic press, Inch pound torque wrench, Seal Installers, Bearing drivers (do not use punches to install bearings) Adjusting nut socket 2-3/4" ID x 8" long, 16 Ga. tubing

NOTE: This procedure should not be attempted in the field due to the need for tools normally only found in the shop.

1.Place upper bearing cones in bearing oven.

2.Seat bearing cups (outer races) in housing using a press and proper installation tools in good condition. CUPS MUST BE FULLY SEATED. If bearing cup cocks in bore and seizes, do not continue to assemble spindle.

3.Lubricate lower bearing cone with LPS.

4.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.

5.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.

6.Lightly lubricate the lip of the seal.

7.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.

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

9.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.

10.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.
