Inspection
Installation
Clean camshaft bearing bores in cylinder block with solvent and blow out with compressed
air. Be sure grooves and drilled oil passages are clean.
Front and rear bearings must be installed last as pilot will not fit into bearing bores if bearings
are installed.
Lubricate outer surface of new camshaft bearings with engine oil to ease installation.
IMPORTANT: All camshaft bearings are not the same. Be sure to install bearings in
proper locations (Indicated by bearing manufacturer) and to position bearings as
follows (directional references are in reference to engine in its normal operating
position):
•
Front bearing must be positioned so that oil holes are equal distance from 6
o’clock position in the block. Intermediate and center bearings must be
positioned so that oil holes are at the 5 o’clock position (toward left side of block
and at a position even with bottom of cylinder bore). Rear bearing must be
positioned so that oil hole is at the 12 o’clock position.
