NOTE: The crosshead has a round hole and an oval hole. If installing new crossheads, it is not required to place the holes in a particular position. If crossheads are being reused, make sure to install them in their original location and orientation. Install the crossheads on the valve stems.
Clean the crossheads with solvent. Dry with compressed air. Inspect the crossheads for cracks and/or excessive wear on rocker lever and valve tip mating surfaces. Inspect the contact pads for cracks and other damage. Replace the crossheads if any damage is found.
NOTE: Make note of the crosshead location and orientation. If the crossheads are reused, they must be installed in their original location and orientation. Remove the crossheads.
NOTE: For engines equipped with a wet flywheel housing, make sure to replace the rear crankshaft seal with the correct rear seal. Rear crankshaft seals for a wet and dry flywheel housings may not be the same. The new rear crankshaft seal (A) will come installed on a seal pilot (B). The seal must be… Read More »
Clean the gasket surface of the cylinder block and rear seal carrier. Dry these areas with compressed air. Inspect the rear seal carrier for cracks or other damage. Replace the rear seal carrier if any damage is found. Use a fine crocus cloth to remove any rust or other deposits from the crankshaft flange. Use… Read More »
Remove the four oil pan mounting capscrews that secure the oil pan to the rear cover. Insert the feeler gauge or shim stock between the rear cover and the oil pan gasket. Move the feeler gauge back and forth to release the gasket from the rear cover. Remove the capscrews from the rear cover. Remove… Read More »
NOTE: This procedure is for front gear train engines only. For front gear train engines, a rear crankshaft seal carrier is mounted to the rear of the cylinder block to house the rear crankshaft seal. For rear gear train engines the rear crankshaft seal is installed in the flywheel housing.
NOTE: Be sure the vibration isolators are installed in the ECM mounting plate prior to installing the capscrews. Install the three mounting capscrews that secure the ECM mounting plate to the cylinder block. Torque Value: 24 N•m [ 212 in-lb ] NOTE: For engines with an aluminum ECM mounting plate, the ECM mounting plate and… Read More »
For an aluminum ECM mounting plate, install the aluminum ECM mounting plate onto the steel yoke. Install the three capscrews attaching the aluminum ECM mounting plate to the steel yoke. Torque Value: 24 N•m [ 212 in-lb]
For an aluminum ECM mounting plate, clear debris from cooling fins and yoke for maximum efficiency. Inspect the ECM mounting plate for cracks. Replace if any damage is found. Remove all grease and paint from the contact surfaces of the ground strap.
