General Information
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.
Install
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 left on the seal pilot while
installing the seal onto the nose of the crankshaft. This will ensure the lips of the seal do not get damaged during
installation.
Install the rear crankshaft seal carrier and gasket. Loosely tighten the rear seal carrier mounting capscrews at this
time.
NOTE: It may be necessary to trim the rear seal carrier gasket so that it is even with the oil pan mounting surface.
Apply a thin bead of sealant, Part Number 3164067, at this joint prior to installing the rear seal carrier. The rear seal
carrier must be installed within 10 minutes of applying the sealant.
To aid in installation, the lubricating oil seal requires the application of a mild soap on the outside diameter of the
seal case.
Place the new rear crankshaft seal, with the seal pilot, over the crankshaft nose and slide it by hand toward the
flywheel housing.
Remove the seal pilot.
Use the disposable seal driver for Front Gear Train engines to drive the rear crankshaft seal into the rear
crankshaft seal carrier.
NOTE: Service tool, Part Number 3824078, used to install the rear crankshaft seal/wear sleeve assembly can also be
used to install the rear crankshaft seal.
Use a plastic hammer to drive the seal into the housing until the alignment tool stops against the housing.
Hit the tool at 12, 3, 6 and 9 o’clock positions to drive the seal evenly and to prevent bending the seal carrier. Hit the
seal driver until contact is made with the rear crankshaft seal carrier.
Align the rear cover even with both sides of the oil pan rail on the cylinder block.
Tighten the rear cover capscrews.
