FUEL INJECTION ADVANCE CONTROL REPAIR
The bevel gear shaft bearing must be shimmed to assure proper meshing of the
bevel gear (endplay). Endplay is assured by controlling dimension C (A + B)
and must be between 2.6605 and 2.6625 inches (67.5767 and 67.6275 mm).
Failure to comply may result in premature failure.
1. Determine shim (36) thickness.
a. Measure the thickness (A) of ball bearing (34) at its thickest point.
b. Measure the thickness (B) from face of bevel gear (27) to bearing seat.
c. Add thickness (A) and (B), then subtract from 2.6605 (67.5767 mm) and
from 2.6625 inch (67.6275 mm) to arrive at shim dimension range.
The shim pack has several 0.002-inch (0.0508-mm) laminations.
Shims may be stripped from the pack to obtain dimensions.
d. Add or remove 0.002-inch (0.0508 mm) shim laminations from shim pack until required
dimension (C) 2.6605-2.6625 inches (67.5767-67.6275 mm) is obtained.
Install shim (36) of predetermined thickness on bevel gear shaft (27).
Press new ball bearing (34) (item 7.1 WP 0175) (with bearing trademark facing out) on bevel
gear shaft (27).
Install eye bracket (35) over ball bearing (34) using a soft-faced hammer.
Install plug (32).
a. Secure plug (32) with new retaining ring (33) (item 290, WP 0175).
