4. Measure camshaft journal outside diameters (O.D.).
5. Measure ID of camshaft journal bores.
6. Calculate oil clearance by subtracting journal O.D.'s from
journal bore I.D.'s. Compare to specification.
NOTE: Replace camshaft if damaged or if any part is
worn past the service limit.
NOTE: Replace engine block if camshaft journal
bores are damaged or worn excessively.
ENGINE REASSEMBLY
CRANKCASE REASSEMBLY
NOTE: Before assembly, clean the bolts and bolt
holes with Primer N (PN 2870585) to remove any
debris. This will ensure proper sealing when
installing bolts.
1. Install oil pick up (A), if removed. Torque to specification.
2. Install oil baffle weldment (B). Torque bolts to
specification.
3. Install the balance shaft. Inspect balance shaft clearance
(C) in both gearcase halves. Rotate balance shaft to ensure
that there is clearance between it and oil baffle weldment.

CAUTION
After any reassembly or rebuild, the engine must be
primed using the Oil Priming Adapter (PU-45778)
and a 3/4-full oil filter before initial start-up. Follow
Steps 45-46 of this section to prime the engine and
to help aid proper break-in.
