H = Allowance for honing
0.020 mm (0.0008 in.) or less
(c)
Bore and hone cylinder to calculated
dimensions
Maximum honing:
0.02 mm (0.0008 in.)
NOTICE:
Excess honing will destroy the finished roundness.

INSPECT CRANKS HAFT F O R RUNO UT
(a)
Place the crankshaft on V--blocks.
(b)
Using a dial indicator, measure the circle runout at the
center journal.
Maximum circle runout:
0.03 mm (0.0012 in.)
If the circle runout is greater than maximum, replace the crank-
shaft.
