joints at exhaust pipe connections on engine left and
right sides.
3. Install new gasket at wastegate/exhaust pipe
flange connection. Align wastegate flange to exhaust
pipe flange using new bolts. Do not install nuts at this
time.
4. Install V- band clamp on exhaust pipe to turbine
connection. Verify
alignment of exhaust pipe to turbine.
Torque V- bland clamps (ref. 81- 30- 01 - INSPEC-
TION “V” BAND CLAMP) and safety.
-NOTE-
Tailpipe V- Band clamps shall be repl aced with a
new clamp after two (2) removals or as refer-

flange attaching bolts. Torque per CMI specifications.
6. Reattach oil inlet line.
7. Reattach oil breather line and tighten clamps.
From engine right side:
8. Tighten crossover pipe stabilizer bracket attaching
hardware so that no vertical movement is evident in at-
taching hardware but enough horizontal play remains
to allow thermal expansion movement of crossover
pipe on bracket.
Engine installation torque values are as follows:
1. Spark plugs - 300 to 420 inch lbs.
2. Hose clamps - 15 to 25 inch lbs.
3. Engine shock mount bolts - 450 to 500 inch lbs.
