Information

A combination oil seal and bearing assembly has replaced the separate crankshaft pilot bearing and clutch housing oil seal assemblies used previously.

The new seal and bearing assembly is mounted in the clutch housing bore (Fig. 1). An extended outer track ring on the bearing also serves as the throw-out bearing support and slide surface. The bearing is lubricated through oil channel B in the clutch housing and oil hole A in the bearing outer track ring (Fig. 1).
Filing Instructions

I.S. Notes with the M.R. 171 designation are to be filed in the new M.R. 171 binder which will be issued shortly. Until this binder is available, please file all M.R. 171 I.S. Notes at the front of your Mechanical S.R.T. manual.

FIGURE 2:

Service Identification and Interchangeability

Manual transaxles designed for use with the new seal and bearing assembly have a short clutch shaft without a pilot bearing hub (Fig. 2). Prior model transaxles have a long clutch shaft with a pilot bearing hub (Fig. 2). The new short clutch shaft does not extend into the crankshaft.
NOTE: Both types of manual transaxles and clutch housings will be supplied for service use. Be sure to identify the type of clutch shaft and housing before ordering parts or proceeding with reassembly. A pilot bearing must be used with the long clutch shaft but is not needed with the newer short shaft. In addition, a separate clutch housing seal is required with prior model clutch housings. The new short clutch shaft can be used on crankshafts which are drilled for a pilot bearing.
Clutch Disc Replacement

Clutch disc replacement procedures are basically unchanged for models with the new seal and bearing assembly and short clutch shaft. The only exception being that a clutch disc aligning tool is not needed during disc replacement.

NOTE: When replacing the pilot bearing on models with the long clutch shaft coat the outer track ring of the bearing with Loctite 648 or 680 if the flywheel bolts are not secured with a lockplate.

Oil Seal and Bearing Assembly Replacement

1. Remove the clutch housing as outlined in the appropriate workshop manual.

2. Press the old seal and bearing assembly out of the clutch housing (Fig. 1).

3. Coat the bearing bore in the clutch housing with Molykote BR.2.

4. Align oil holes A and B in the clutch housing and bearing (Fig. 1) and press the new assembly into the clutch housing. Be sure the seal is flush against the housing.
