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 posi-
tioned 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.
1.
Installing intermediate and center bearings:
a. Install nut and thrust washer all the way onto puller screw, then position pilot in front
camshaft bearing bore and insert screw through pilot.
b. Index center camshaft bearing, then position appropriate size remover and installer
tool in bearing and thread puller screw into tool. Be sure at least 1/2 in. (13 mm) of
threads are engaged.
c. Using two wrenches, hold puller screw and turn nut until bearing has been pulled into
position. Remove the remover and installer tool and check to ensure that oil hole(s)
in bearing are positioned correctly.
d. Install intermediate bearings in same manner being sure to index bearings correctly.
It will be necessary to position pilot in rear camshaft bearing bore to install rear
intermediate bearing.
