Using camshaft bearing remover and installer set
(J-6098-01) (with nut and thrust washer installed
to end of threads), position pilot in front camshaft

Inspection
Clean camshaft bearing bores in cylinder block with
solvent and blow out with compressed air. Be sure
grooves and drilled oil passages are clean.
3.
4.
Install tool with shoulder toward bearing. Be sure
a sufficient amount of threads are engaged.
Installation
Using two wrenches, hold puller screw while turn-
ing nut. When bearing has been pulled from bore,
remove tool and bearing from puller screw.
Front and rear bearings must be installed last as pilot
will not fit into bearing bores if bearings are installed.
5.
Remove remaining bearings (except front and
rear) in same manner. It will be necessary to posi-
tion pilot in rear camshaft bearing to remove rear
intermediate bearing.
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 loca-
tions (Indicated by bearing manufacturer) and to
position bearings as follows (directional refer-
ences are in reference to engine in its normal op-
erating position):
a
•
Front bearing must be positioned so that oil
holes are equal distance from 6 o’clock posi-
tion 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 posi-
tioned so that oil hole is at the 12 o’clock posi-
tion.
