CAUTION: The sealing surface on the crankshaft must be free from all oil residue to prevent seal leaks.
If the gear cover has been recently removed and replaced, use the alignment tool from the seal kit to make sure the cover is aligned with the
crankshaft.
Apply a bead of Loctite 277 to the outside diameter of the seal. Install the pilot from the seal kit onto the crankshaft.
Install the seal onto the pilot and start it into the front cover seal bore.
Remove the pilot.
Use the alignment/installation tool and a plastic hammer to install the seal to the correct depth.
