This will be a brief section dealing with the main drive gear and the cluster gear for this transmission. Naturally, both parts have already been cleaned and inspected.

The front ball bearing must be pressed onto the journal of the main drive gear. The front oil baffle is dropped in place first. These are slightly offset to allow a bit of space for the 16 teeth of the drive gear to reside. The bearing has a snap ring groove offset to one side......this will always go toward the front.

The fit of the bearing to the drive gear is a tight press fit. Our press is rated at 20 tons and can handle this with ease. Always put a couple drops of oil on the journal surface before pressing something into place. We use an old bearing race to support the inner race of the new bearing while pushing on the front pilot end of the drive gear. Make sure that the oil baffle is not sitting slightly in the snap ring groove before you began to apply pressure. Once past the groove, you don't have to worry about the baffle as it will travel with the new bearing into place. Make sure that the bearing is fully seated, and that the snap ring groove in the drive gear is just beyond the edge of the bearing.

The B-7064 snap ring can now be installed with your lock ring pliers. Make sure that it is fully seated into its groove. Then install the large snap ring (B-7026) in the outer groove of the new bearing.

The complete main drive gear & bearing assembly can be installed to the front of the gearbox case. The fit is usually pretty close so you may have to tap the front of the input shaft with a soft hammer to seat the bearing to the case. Use a single bolt and washer to secure the assembly to the gearbox for now.
