Suburban 3/4 Ton 4WD V8-305 5.0L (1986)
Fig. 2 Removing pulley rotor & bearing assembly
1.
Refer to ``Compressor Clutch Plate & Hub Assembly'' procedure to remove clutch plate and hub.
2.
Remove rotor and bearing assembly retaining ring.
3.
Place puller guide J-33023 or equivalent on front head and engage puller J-33020 or equivalent into inner circle of slots in rotor by turning
clockwise, Fig. 2.
4.
Hold puller in place and tighten puller screw against puller guide to remove pulley rotor and bearing assembly.
5.
Remove forcing screw from puller and invert assembly on solid flat surface. Rotor hub must be properly supported during bearing removal.
6.
Drive bearing out of rotor hub with rotor bearing remover J-9398 and J-8092 handle. It is not necessary to remove staking in front of bearing
during removal. Old stake metal will have to be filed away to ensure proper clearance for installation of new bearing.
Installation
1.
Place pulley rotor on support block J-21352-A or equivalent. Do not support rotor by resting pulley rim on flat surface, or rotor face will be bent
during bearing installation.
2.
Align new bearing squarely with hub bore and drive bearing into hub by applying force to outer race of bearing with installer J-9481 and handle
J-8092.
3.
Stake bearing in 3 places 120° apart, being careful to shift support block to give full support under area of hub being staked. Stake should be
formed down to but not touching bearing to avoid distorting outer race.
4.
With compressor mounted vertically, position rotor and bearing assembly on front head.
5.
Position J-33017 installer and J-33023 pilot over inner race of bearing.
6.
Set puller crossbar T-8433-1 or equivalent on puller pilot J-33023. Assemble 2 through bolts and washers J-33026-2 through puller bar slots and
thread into holding fixture J-33026 so full thickness of holding fixture is engaged.
7.
Tighten center screw of puller crossbar to force pulley rotor and bearing assembly onto compressor front head, ensuring installer maintains direct
in-line contact with inner race of bearing.
8.
Install rotor and bearing assembly retainer ring.
9.
Reinstall clutch plate and hub assembly.
