Install nine bolts (4) and washers (5) in engine retarders (6). Tighten bolts to 40 lb-ft (54 Nm).
7.
Repeat tightening of nine bolts (4) to 80 lb-ft (108 Nm).
8.

ADJUSTMENT
CAUTION
Failure to use slave piston adjustment procedure will cause poor engine brake performance and/or serious
engine damage. It is necessary to rotate engine to put exhaust valves in closed position for each cylinder
being adjusted. Make sure proper engine valve lash has been obtained to prevent damage to equipment.
1.
Loosen lock nut (22) and back out adjusting screw (23) in slave piston bridge (31) until end of adjusting screw is flush
with bottom surface of slave piston bridge (31).
2.
Place 0.023 in (0.584 mm) thickness gage between solid side of slave piston bridge (31) and exhaust rocker arm adjust-
ing screw (36).
3.
Loosen lock nut (38) and turn adjusting screw (37) clockwise until light drag is felt on thickness gage.
4.
Hold adjusting screw (37) in position and remove thickness gage.
5.
Tighten lock nut (38) to 26 lb-ft (35 Nm).
6.
Using 0.023 in (0.584 mm) thickness gage, check clearance between adjusting screw (23) and rocker arm adjusting
screw (39).
7.
Turn adjusting screw (23) clockwise until light drag is felt on thickness gage.
