4-6. CHASSIS SPINDLE ASSEMBLY MAINTENANCE (CONT)
INSTALLATION (SHEET 3 OF 3)
If necessary, use jack to raise or lower rear chassis until spaces between
front and rear chassis are equal.
Install upper spindle (3).
Install six capscrews (1) and lock washers (2) in upper spindle (3). Tighten
capscrews to 200 to 240 lb-ft.
Start thrust bearing (6) into front chassis. Using hydraulic pusher and 3-7/8

pusher and sleeve.
Install upper thrust plate cap (8) using six capscrews (1) and lock washers
(2). Tighten capscrews (1) evenly until thrust plate cap (8) contacts thrust
Using thickness gage, measure space between thrust plate cap (8) and front
chassis (13). Record measurement. This measurement is thickness of shims (9
thru 11) that must be installed.
Support thrust plate cap (8) and loosen and remove six capscrews (1) and lock
washers (2). Remove thrust plate cap (8). Install shims (9 thru 11) thickness
as measured and recorded in step 1 above.
Position thrust plate cap (8) and install and tighten six lock washers (2) and
capscrews (1). Tighten to 200 to 240 lb-ft.
Install lubrication fitting (7).
Repeat steps a through o above to install lower chassis spindle parts.
