not be installed until the crankshaft,
seals and bearings are completely
seated in the upper half. Attempting to
force the parts into place will damage
the parts.

crankcase.
4. Make sure the crankcase mating surfaces are
completely clean and dry.
5. Apply RTV High Temperature Sealant (part
no. 0636-069) to the entire mating surface of the
crankcase half.
6. Position the other crankcase half onto the
crankshaft and the other case half. If the lower
crankcase half is being assembled onto the
crankshaft and upper case half, make sure the

crankcase halves will not fit together until the
bearings are completely seated. Any attempt to
force the case halves together will damage the
parts.
