Checks and Adjustments

Front End Play Check

CAUTION: Be sure the pump body is seated against the washer and overdrive drum. The pump body must be below the level of the case gasket surface.






1. To perform the front end play check procedure, place any No. 1 thrust washer on the rear of pump using petroleum jelly to hold the washer in place. The washer tabs go into the pump face. Place the pump into position in the case.

2. CAUTION: Gauge bar must rest on gasket surface.

Place Gauge Bar T93T-77003-AH across case as shown.

3. Place the micrometer on gauge bar, extend probe until it contacts pump surface.

4. Read micrometer and subtract the thickness of gauge bar (17.78mm [ 0.700 in]). Record this as Dimension "A."

5. Move Gauge Bar T93T-77003-AH to opposite side of case (180 degrees).

6. Repeat Steps 3 and 4 and record measurement as Dimension "B."






7. Add Dimensions A and B together, divide by 2 and this is your front end clearance, Dimension "C."

CAUTION: If your average is below the specification choose a washer of less thickness. If your average is above specification choose a thicker washer.

NOTE: The front end play specification is .018-.64mm (.007-.025 inch).






8. NOTE: The tabs on the washer go into the pump face.

Remove the pump and install the correct No. 1 thrust washer. Use petroleum jelly to hold the washer in place.
