TRANSMISSION HOUSING ASSEMBLY

The die-cast aluminum transmission housing has four studs pressed into its upper region. The studs provide mount- ing for the two crank and two cluster gears. The top cover is threaded into the lower housing. A sealant is used on the threads as a gasket material. A steel drive tube with a splined end is pressed into the bottom of the transmission hous- ing. A sleeve bearing is installed in the lower I. D. of the drive tube. Another bearing is pressed into the lower housing above the drive tube. These bearings provide a path for the drive shaft to ride in. An oil seal is installed in the bottom of the drive tube. The oil seal can be re- placed as a separate part.

Oil Seal Replacement:

The oil seal is located in the spline end of the drive tube. The seal can be replaced without removing or disassembling the transmission, as outlined below:

1.Disconnect the unit from the power source.

2.Remove the brake assembly to access the seal.

3.Use a thin, flat bladed screwdriver to carefully pry the old seal out.

4.Place the drive washer (tool number 14242) and the new seal over

the seal protector.

5.Remove the cone-shaped end from the seal protector tool and slide the tool, drive washer, and new seal over the drive shaft up to the seal cavity.

6.Slide the transmission seal driver (tool number 14242) over the drive shaft until it makes contact with the drive washer. Use the impact sleeve of the tool to "tap" the seal into the end of the drive tube.

LOWER BEARING ASSEMBLY

The lower bearing assembly consists of a ball type bearing which has been installed in an aluminum die-cast housing. The transmission assembly must be removed from the washer cabinet before the lower bearing assembly can be replaced.

The lower bearing assembly provides lateral support for the drive tube and shaft against the tension of the drive belt. The top of the suspension housing

is attached to the underside of the lower bearing assembly.

REPLACEMENT:

IMPORTANT

Because the lower bearing assembly has been pressed onto the drive tube under approximately 1,000 pounds of pressure, a puller must be used to remove it. However, the puller forcing screw must not be used on the end of the drive shaft or the clutch assembly could be damaged. Instead, a simple pipe and cap as- sembly can be made to slip over the drive shaft, with end clearance, and rest against the end of the drive tube.
