This Service Information bulletin announces a design change to the clutch release bearing used on the models as listed above.
Read full bulletin
During assembly of the bearing, a different type of grease is used which has a higher resistance to heat. In cases where the operator keeps a foot on the clutch pedal for extended periods, an increased amount of heat is generated which can cause the grease inside the bearing to deteriorate. In a case of prolonged clutch pedal application, seizure of the bearing can occur with potential damage to other related components.

HIGH-PITCHED SOUND COMING FROM THE TRANSMISSION EXTENSION HOUSING AREA. IN COLD TEMPERATURES, THERMAL CONTRACTION CAUSES SHRINKING OF THE TRANSMISSION CASE. IN HIGH TEMPERATURES, EXPANSION OF THE CASE OCCURS. THESE TEMPERATURE CHANGES AFFECT THE AMOUNT OF PRELOAD ON THE TRANSFER DRIVEN SHAFT BEARINGS. IN SOME RARE CASES, WHEN PRELOAD IS VERY NEAR THE LIMIT OF SPECIFICATION COMBINED WITH UNUSUAL DRIVING CONDITIONS, THIS THERMALLY-INDUCED PRE-LOAD CHANGE MAY CAUSE DAMAGE TO THE BEARINGS AND RESULT IN THE SOUND HEARD BY THE CUSTOMER. A CHANGE HAS BEEN MADE TO THE EXTENSION CASE AND A NEW DISH PLATE ADDED. THE MACHINING DEPTH OF THE EXTENSION CASE HAS BEEN INCREASED TO ACCOMMODATE THE NEW DISH PLATE. WHEN USED ALONG WITH A SELECTIVE THRUST WASHER, THE SPRING TENSION OF THE DISH PLATE HELPS TO MAINTAIN A CONSISTENT AMOUNT OF PRE-LOAD ON THESE BEARINGS THROUGHOUT VARYING TEMPERATURE CONDITIONS.
