crankshaft. Make sure the marks on the
flywheel and crankshaft are in alignment.
Put 8H5137 Gasket Sealer on the bolt threads
and install bolts (1). Tighten the bolts to a

bolt threads. The holes for the bolts in the crankshaft
flange are drilled through making the holes open to the
oil in the engine. Leaking along the bolt threads can be
the result if the correct sealant is not used.
CAUTION: When installing a new flywheel, check the
thickness of the new flywheel at the bolt holes in relation
to the thickness of the old flywheel. Install the correct
length bolts so they will be fully engaged in the
crankshaft flange. Bolts that are too long will make
contact with the block on back side of the crankshaft
flange and pull crankshaft back. This will cause the
crankshaft thrust bearing to fail.
