− CYLINDER BLOCK
(2) Calculate the amount of each cylinder is to be re-
bored as follows:
Size to be rebored = P + C − H
P = Piston diameter
C = Piston clearance
0.047 − 0.070 mm (0.0019 − 0.0028 in.)
H = Allowance for honing
0.020 mm (0.0008 in.) or less
Bore and hone cylinder to calculated dimensions
Maximum honing:
0.02 mm (0.0008 in.)
INSPECT CRANKSHAFT FOR RUNOUT
Place the crankshaft on V−blocks.
Using a dial indicator, measure the circle runout at the
center journal.
Maximum circle runout:
0.03 mm (0.0012 in.)
INSPECT MAIN JOURNALS AND CRANK PINS
