Specifications

(2) Check internal diameter of bearings.
(3) If internal diameter of original bearing is being
checked and figures are not within specifications,
new bearings must be used.
(4) Check crankshaft main bearing journals to
bearing clearances. Clearances of main bearings is
.03 to .088mm (.0011 to .0035 in.).
OIL PAN
Remove all gasket material from cylinder block. Be
careful not gouge pan sealing surface.
CYLINDER LINER
INSPECTION
The cylinder walls should be checked for out-of-
round and taper with dail bore gauge. The cylinder
bore out-of-round is 0.100 mm (.0039 inch) maximum
and cylinder bore taper is 0.100 mm (0.0039 inch)
maximum. If the cylinder walls are badly scuffed or
scored, new liners should be installed and honed, and
new pistons and rings fitted.
Measure the cylinder bore at three levels in direc-
tions A and B (Fig. 97). Top measurement should be
10 mm (3/8 inch) down and bottom measurement
should be 10 mm ( 3/8 inch.) up from bottom of bore.
