The above torque specifications allow for the drag of the hub spindle oil seal. However, if a felt dust seal is
used in the inside of the brake drum, the torque specifications should be increased by 5 lb ft.
If wheel bearings are being reused, they should be put back in same position as before. Advance the adjusting
nut in small increments and check rotating torque until an increase is noted. If increase is slight, install nut lock
in this position or back off nut enough to install nut lock. If increase is appreciable, back off nut until increase is
only slight or none and then install nut lock.
If it is not convenient to remove the wheels of the vehicle, check the wheel bearing preload torque
as shown above (refer to Fig. 8). The extension (see inset) permits a reading to be taken without interference
from the tire.
Bearing preload torque is figured by multiplying the radius (the distance from the center of the
wheel to the center of the extension) by the reading on the pound scale.
For Example: Assume the distance from the center of the wheel to the center of the extension is 9 inches and
the reading on the pound scale is 7 pounds (refer to Fig. 8 and 9). Multiplying 9 inches by 7 pounds, we get 63-
pound inches. Since our preload specifications are listed in pound feet (lb ft), we simply divide the 63-pound
inches by 12 and arrive at a reading of 5.25-pound feet.
This method of converting pound inches to pound feet also applies to Step 3 above.
ASSEMBLE PLANETARY SPIDER (Refer to Fig. 10.)
Place the planetary spider cage on a bench or block up on metal plates.
