6. Disc (vibrator motor side)
1) Press the bearing outer race into disc (8).
2) Using a hoist, position disc (8) on axle
shaft (9).
3) Apply grease to the bearing and press it
into axle shaft (9).
4) When installing cover (7), make a preload
adjustment by using shims as follows:
4.1) After installing the bearing, fit the
removed shims. Tighten four securing
bolts of cover (7) to 12.7 N·m (1.3 kgf·m).
Then rotate disc (8) one turn clockwise
and one turn counterclockwise. Retighten
the bolts to the above-mentioned torque.
4.2) After that measure the clearnce between
cover (7) and axle shaft (9) with a
thickness gauge. Fit shims with their
thickness equivalent to the clearance.
Retighten the four bolts to 59 N·m (6.0
kgf·m).
4.3) Then spin disc (8) two turns clockwise
and counterclockwise each, hook a spring
balance to a shockmount fastening bolt
and measure the force when the disc
starts spinning (disc drag).
・
Disc drag: 64 N·m (6.5±0.3 kgf·m)
(SW352, TW352)
45 N·m (4.5±0.3 kgf·m)
(SW502, TW502)
If the drag is lower than specified,
increase shim thickness.
If the drag is higher than specified,
decrease shim thickness.
