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 bolts and bolt holes
with Primer N (PN 2874275) 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 to specification.
