NOTE:
THIS BULLETIN APPLIES TO 2000 - 2003 (AN) DAKOTA TRUCKS EQUIPPED WITH A 4.7L ENGINE (SALES CODE EVA) AND 5
SPEED MANUAL TRANSMISSION (SALES CODE A36). 2002 - 2003 (DR) RAM TRUCK EQUIPPED WITH 3.7L, 4.7L OR 5.7L ENGINE
(SALES CODE EKG, EVA, OR EZA) AND 5 SPEED MANUAL TRANSMISSION (SALES CODE A36, A64, OR A74).
DISCUSSION:
The clutch housing maintains alignment between the crankshaft and transmission input shaft. The structural cover provides additional powertrain
stiffness and reduces noise and vibration. If either one is bolted to the engine or to each other, in the wrong sequence, drivetrain misalignment could
result. Misalignment could result in reduced life expectancy of drivetrain components such as the clutch disc assembly, pilot bearing, clutch release
components, and transmission.
If misalignment is suspected and the clutch housing bore runout is found to be excessive using the diagnostic procedures in the service manual or if the
clutch housing and structural cover has been removed for any reason, the components should be installed using the following Repair Procedure.
REPAIR PROCEDURE:
1.
Open the hood.
2.
Disconnect the negative battery cable.
3.
Remove the transmission as outlined in the service information available in MDS2 or the 2003 DR Ram Truck Service Manual (Publication No.
81-370-03059) page 21-43 (5.7L only).
4.
Clean the clutch housing mounting surface of the engine block using Mopar Engine Degreaser pin 04318040 (or equivalent).
5.
Verify that the clutch housing alignment dowels are in good condition and properly seated.
CAUTION:
THE STRUCTURAL COVER MUST BE INSTALLED AS DESCRIBED IN THE FOLLOWING STEPS. FAILURE TO DO SO WILL
CAUSE SEVERE DAMAGE TO THE COVER, AND ENGINE NOISE.
