ENGINE – ENGINE MECHANICAL
3. HONE NEW BUSHING AND CHECK PIN FIT IN
CONNECTING ROD
(a) Hone the new bushing and check that the oil clear–
ance is within standard specification.
Standard oil clearance: 0.005 – 0.011 mm
(0.0002 – 0.0004 in.)
(b) Check the pin fit at the normal room temperature.
Coat the pin with engine oil and push the pin into the
rod with thumb pressure.

CRANKSHAFT INSPECTION AND REPAIR

1. MEASURE CRANKSHAFT FOR RUNOUT

(a) Place the crankshaft on V–blocks.
(b) Using a dial gauge, measure the runout at the center
journal.
Maximum circle runout: 0.1 mm (0.004 in.)
If the runout is greater than maximum, replace the
crankshaft.
HINT: Use a long spindle on the dial gauge.

2. INSPECT MAIN JOURNALS AND CRANK PINS

(a) Using a micrometer, measure the diameter of the main
journal and crank pin.
Main journal diameter: 59.984 – 60.000 mm
(2.3616 – 2.3622 in.)
Crank pin diameter: 52.988 – 53.000 mm
(2.0861 – 2.0866 in.)
If journals are worn, regrind or replace the crankshaft.
(b) Measure the journals for out–of–round and taper as
shown.
Maximum taper: 0.01 mm (0.0004 in.)
Maximum out–of–round: 0.01 mm (0.0004 in.)
If taper and out–of–round are greater than maxi–
mum, regrind and/or replace the crankshaft.
