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
fr
om 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 the engine crankcase assembly if
c
amshaft journal bores are damaged or worn
excessively.
ENGINE REASSEMBLY
Crankcase Reassembly
NOTE: Before assembly, clean the bolts and bolt
holes with Loctite Primer N (commercially available)
to remove any debris. This will ensure proper
sealing when installing bolts.
1. Install oil pick up (A). Torque bolt
to specification.
2. Install oil baffle weldment (B)
. Torque bolts to
specification.
3. Install balance shaft. Inspect balance shaft clearance
(C)
in both gearcase halves. Rotate balance shaft to
ensure there is clearance between it and the oil baffle
weldment.

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 (see “Oil Pump Priming”).
