This addresses proper seating of the oil seal that is
installed in the flywheel end of the case.
Of course, you have the engine removed; the clutch and
pressure plate removed; and finally, the large gland nut and pressure plate
- It should fit far enough into the case that its outer surface does NOT
protrude beyond the surrounding surface of the case. Gently tapping in
with a light shot mallet or using an installation "washer" should be
- Failure to meet this requirement will cause early seal failure
and/or interference with crankshaft endplay as the flywheel back
(face) surface can rub against it.
What can prevent the seal from going in all the way?
Be Careful! Donít remove case
material other than protrusions! The case is magnesium.
Glue residue - Some engine builders use a gluey substance in the hope
of obtaining a better seal against leaks. If this old glue is not removed,
it can create enough "grab" that the seal will not easily install
properly. I would suggest something no stronger than a metal brush.
Be Careful! Donít remove case material!
- Before installing the seal, check the bore into which it is going, for
burrs, dings, etc., and gasket sealer/glue.
- Carefully remove any burrs, etc., which protrude.
