scores are too deep to be removed or if parts are badly

worn, replace parts.

(5) The clearance between new shafts and new

bearings is 0.0045 to 0.006 inch or a maximum of

0.008 inch with used parts. Excessive clearance

between the shafts and the bearings will cause low oil

pressure and excessive back lash between the gears.

Replace badly worn parts.

(6) Bearings are available in 0.010 and 0.020 inch

undersize for use with worn or reground camshafts.

(7) Oversize camshaft and balance shaft bearings

are available in sets, 0.010 inch oversize on the outside

diameter, for use with a cylinder block having one or

more scored block bearing bores.

(8) Remove end bearings if necessary as follows:

CAUTION

When removing camshaft bearings, note the

position of the bearings in the block bore with

respect to the notch in the bearing. Replace-

ment bearings must be installed in the same

position.

NOTE

End bearings must be removed before remov-

ing intermediate bearings.

(a) Insert small diameter of pilot (fig. 3-122)

into bore of an end bearing.

(3) Inspect both faces of each thrust washer. If

(b) Position the remover tool as shown in the

either face is scored or if the thrust washers are worn

excessively, replace the washers. New thrust washers

are 0.208 to 0.210 inch thick.

(4) Inspect the surfaces which the thrust washers

contact; if these surfaces are scratched but not severe-

ly scored, smooth them down with an oil stone. If the
