Repairing Steering Head And Bearings

Each steering head bearing consists of two pieces, the bearing outer race, and the roller bearing with inner race. The outer races are pressed into the steering head cups in the frame head. The lower roller bearing is assembled over the fork stem and the upper roller bearing is held in place on the fork stem by the upper fork bracket and nut on the upper threaded end of the fork stem.

After fork is removed inspect bearings and races forpitting, roughness or wear. Roughness of the roller bearings can be determined by rolling the bearings on the bearing races by hand. If bearings or races require replacement it is best to replace them in sets.

To replace bearing races (19 and 20, Figure 2-39), knock head cup from steering head using a suitable drift. Press new bearing race in new head cup and then press assembly into frame head.

DISASSEMBLING FORK SIDE - 1975 AND EARLIER (Figure 2-39)

On 1972 and earlier models, use Wrench, Part No. 94694-52, and disassemble retainer (7) from top of fork tube (8). Remove spring (9) and drain hydraulic fork oil from fork tube. Turn assembly upside down and remove bolt and washer (12). It may be necessary to insert Tool, Part No. 95991 -69 or a long screwdriver into 3/32 wide x 1 /2 long slot C (Figure 2-40) in upper end of shock absorber tube to keep it from turning while removing bolt (12). Free slider (10) from tube (8). On 1973 to 1975 models use Socket, Part No. 94556-73, with extension on upper end of shock absorber tube C (Figure 2-40) to keep it from turning.
