The worst killer of manual transmissions we see on Dodge Cummins Turbo-Diesel trucks is a small, often overlooked, inexpensive part that is not even part of the transmission. The pilot bearing or bushing is pressed into the flywheel. It's function is to support the forward end of the transmission input shaft, keep the clutch disc centered on the flywheel, and allow the input shaft and flywheel to rotate independently of each other when the clutch is disengaged. Dodge used a thin bronze pilot bushing on 1989-1993 trucks.

The 1989 model year was the first year Dodge installed the Cummins 6BT Diesel engine in Ram trucks. The original crank seal had a steel outer shell which was pressed into the aluminum seal adapter. Over time, the steel shell would become compressed by the seal adapter due to the different expansion/contraction rates of the two parts. In many cases, the seal shell would get compressed to the point oil would seep between the shell and adapter. Most of the seals I replaced on 1989-1993 engines were so loose, I easily pulled them out with a dental pick. Our current production seals have a ribbed, rubber outside diameter seal so they are not affected by contraction of the aluminum seal shell.
I recommend you use our TS6000 Cummins rear crank seal tool set to install your new seal or seal with wear sleeve. With the TS6000 tools there is absolutely no need to remove the flywheel housing and rear seal adapter. However if for any reason, you do need to remove the rear seal adapter from the back of the block, we do include a Cummins supplied stamped steel centering ring with QU10556 Seal to center the rear seal adapter. The centering ring is required to center the seal adapter because Cummins did not dowel the seal retainer to the block so it can be installed off center unless you use the line up ring. For service procedures, see TSB6000.
