CHAPTER 9

REPAIR OF M915 FRONT AXLE

9-1. Description. The non-driving front axle used on the M915 incorporates sealed knuckle pins and

permanently lubricated tie-rod end assemblies. The axle center section is an l-beam type with integral

spring pads (fig. 9-l).

Figure 9-1. Non-Driving Front Axle Steering Knuckle.

a. Sealed Knuckle Pin.

The sealed knuckle pins are of the straight design, employing two flats for

correct positioning inside the axle center, and are held in place by tapered draw keys. The lubricant is

protected from road contamination by grease seals and gaskets that enclose the upper and lower pin

bushings.

b. Steering Knuckle and Bushing Assembly.

The steering knuckles are bushed in the upper and lower

knuckle pin bosses with steel backed bronze bushings. Top and bottom steering knuckle caps are equipped

with grease fittings for periodic lubrication.

c. Tie-Rod Ends.

The permanently lubricated tie-rod ends employ lube seals to prevent road con-

tamination from the tie-rod ball cavity.
