Rev. “F” 5-1-7
Air Filter and Intake System
Follow RV manufacturer’s recommended filter change interval. Visually inspect intake air
components at each oil change for cracks or loose connections.
Charge Air Cooler
The long-term integrity of the CAC (Charge Air Cooler) system is the responsibility of the vehicle
and component manufacturers. However, CAC diagnostics can be performed at your Cummins
distributor.
Vibration Damper
Inspection required at 72,000 miles/2 years which includes visual inspection for deformation.
Inspect
CAUTION: The silicone fluid in the vibration damper will become solid after extended
service and will make the damper inoperative. An inoperative vibration damper can cause
major engine or drivetrain failures.
Check the vibration damper for evidence of fluid loss, dents, and wobble. Inspect the vibration
damper thickness for any deformation or raising of the damper cover plate.
If any variations or deformations are detected, contact a Cummins distributor for details.
Fan Idler Pulley, Hub and Belt Tension
Inspection required at 36,000 miles/1 year which includes visual inspection of all components.
Fan Hub, Belt Driven
Maintenance Check
Remove the drive belt.
NOTE: The fan hub must rotate without any wobble or excessive end play.
Check the fan hub bearing.

Belt Tensioner, Automatic
Maintenance Check
Every 36,000 miles, 1000 hours, or 1 year, whichever occurs first, inspect the automatic belt
tensioner.
With the engine turned off, check that neither the top nor the bottom tensioner arm stop is
touching the cast boss on the tensioner body. If either of the stops is touching a boss, the
alternator belt must be replaced. Check to make sure that the correct belt part number is being
used if either condition exists.
Visually check the tensioner pulley and body for cracks. If any cracks are noticed, the tensioner
must be replaced. Refer to a Cummins Authorized Repair Facility. Check the tensioner for dirt
buildup. If this condition exists, the tensioner must be removed and steam-cleaned.
Check that the bottom tensioner arm stop is in contrast with the bottom tensioner arm stop boss
on the tensioner body. If these two are not touching, the tensioner must be replaced.
Inspect the tensioner for evidence of the pivoting tensioner arm contacting the stationary circular
base. If there is evidence of these two areas touching, the pivot tube bushing has failed, and the
tensioner must be replaced.
