CONNECTING ROD BIG END OIL
CLEARANCE
Clean all oil from the crank pin and connecting rod big
end surface.
Place a piece of plastigauge on the crank pin, install the
connecting rod upper and the connecting rod lower, and
tighten the connecting rod bolts to the specified torque.
Do not rotate the crankshaft while the plastigauge is in
place.
Remove the connecting rod and measure the
plastigauge.
If the clearance is more than the service limit, inspect
the connecting rod big end I.D. and the crank pin
O.D.(page 13-13).
If necessary replace the part that is not within the
service limit and reinspect the clearance.
CRANKSHAFT RUNOUT
Set the crankshaft on V-blocks and measure the runout
using a dial indicator.
If the measured runout is more than the service limit,
replace the crankshaft (page 13-5).
