CAMSHAFT BEARINGS<br />
(6 & 8 Cylinder)<br />
Replacement camshaft bearings are avail - able through<br />
the service parts department, in both finish reamed and<br />
unfinished. The finish reamed bearings are sufficiently<br />
oversize so that when pressed into place they will be the<br />
proper dimensions, thus eliminating the need for scraping<br />
or reaming. The unfinished bearings have sufficient wall<br />
thickness to permit line reaming where proper equipment is<br />
available for this operation. These bearings should be line<br />
reamed after Installation to a diameter .001" larger than the<br />
individual camshaft journals.<br />
<strong>Service</strong> replacement camshaft bearings are a press fit of<br />
.0026" to .0055" in cylinder block.<br />
When pressing in new bearings, always Install bearings<br />
with the locating notch at the top.<br />
It is advisable to remove the engine from the car if it is<br />
found necessary to replace camshaft bearings.<br />
Installation:<br />
CAMSHAFT<br />

guide camshaft through bearings.<br />
2. Install camshaft gear aligning timing marks with crankshaft<br />

gear must locate between the punch marks of the camshaft<br />
gear. Install lock wire through bolt heads and secure.<br />

NOTE: Tappet guides must be accurately aligned with<br />
cams on camshaft. Position of guides is controlled by the<br />
guide clamps; the inner sides of which should be in full<br />
contact with matching flat surfaces on front face of each<br />
pair of tappet guides within .0015", Figure 42.
