Actuator Control Linkage Lubricate
(If applicable)
Actuator Control Linkage Replace
SMCS Code: 1265-086
Inspect the rod ends of the following components for
wear:
The linkage can move and form a pinch point
which can cause personal injury. Keep hands
away from the linkage.
Before performing this procedure, ensure that the
linkage is meant to be lubricated. If the linkage is
meant to be lubricated, this article applies to the
following: air choke actuator, fuel control actuator,
and exhaust bypass actuator.
Apply Dow Corning 41 Extreme High Temperature
Bearing Grease to the rod ends (bearings) of the
control linkage for the actuator. For more information
on grease, see the Special Publication, SEBU6400,
“Caterpillar Gas Engine Lubricant, Fuel, and Coolant
Recommendations”.
SMCS Code: 1265-510
Note: Use of a platform may be necessary to reach
the linkages.
• Air choke actuator
• Exhaust bypass actuator
• Fuel control actuator
• Linkages
If necessary, replace the rod ends.
Removal and Installation
Note: The exhaust heat shields must be in place and
snug around the shaft of the wastegate in order to
provide maximum life of rod ends.
