ENGINE
BEARING CLEARANCE
(1) The. total: clearance of the main bearings can only be
determined by removing the weight of the crankshaft .
This is accomplished by having the engine turned upside
down on the engine stand. This will remove all the crank-
weight off the bearing surface.
(2) Place, a piece of Plastigage across the entire width of
the bearing shell in the approximately 6.35 mm
in.) off center and away from the oil holes. In addition,
suspect areas can be checked by placing the Plastig age
in the suspect area.
Torque the
bolts of the bearing being checked
to the proper specifications.
Caution
Do not rotate crankshaft, or the Plastigage may be
smeared.
(3) Remove the and compare the width of the flat-
tened Plastigage with the metric scale provided on the
package.
Standard value: mm in.)
Stretched
boltThreads are straight on line,
Unstretched bolt
MAIN BEARING BOLTS
(1) Since the main bearing bolts are torqued using a new
procedure, they should be examined BEFORE reuse.
If the threads are necked down, replace the bolts.
(2) Necking can be checked by holding a scale or st raight
edge against the threads. If all the threads do not contact
the scale, the bolt should be replaced.
CHECKING CRANKSHAFT END PLAY
(1) Mount a dial indicator to front of engine, locating probe
on nose of crankshaft.
(2) Move crankshaft all the way to the rear of its travel using
a lever inserted between a main bearing cap and a c rank-
shaft cheek, using care not to damage any bearing sur-
face, Do not loosen main bearing cap.
(3) Zero the dial indicator.
(4) Move crankshaft all the way to the front and re ad the
dial indicator.
Standard value: mm in.)
Limit: 0.37 mm
in.)
(5) Replace No. 3 main bearing if limit is exceeded and re-
measure.
(6) Replace crankshaft if limit is still exceeded.
