For engines with wet flywheel housings, apply a 1.5 to 2.0 mm [0.06 to 0.09 in] wide bead of sealant, Part Number 3164067, to the flywheel housing starting motor mounting flange. NOTE: If a starting motor spacer is required, make sure to apply sealant to the side of the spacer that contacts the starting motor.… Read More »
Use an inside micrometer or a vernier caliper to measure the distance from the starting motor mounting flange to the forward face of the front side of the flywheel ring gear. NOTE: Include any spacers previously removed when completing the measurement. Add or remove spacers as necessary to achieve the correct starting motor spacing.
For engines that use wet flywheel housings, clean any left over sealant from the starting motor mounting flange on both the flywheel housing and starting motor. Make sure these surfaces are clean of oil and debris.
Remove the three capscrews and the starting motor. NOTE: If equipped with a starting motor spacer, remove the spacer and clean all surfaces between the starting motor, starting motor spacer, and flywheel housing with a wire brush.
• Disconnect the batteries. Refer to the OEM service manual. • Identify each wire with a tag indicating location on starting motor. • Remove the electrical connections from the starting motor. Prior to removing the starter, use steam to clean the area around the starting motor to prevent debris from entering the flywheel housing. Dry… Read More »
