Measure the thrust clearance, using a dial gauge.
Thrust Clearance
Specified Value:
Allowable Limit:
If the thrust clearance exceeds the allowable limit, mea-
sure the width of the crankshaft thrust bearing contact sur-
face. If the measured value is less than 23.59 mm, replace
the thrust washer. If the measured value exceeds
23.59 mm, replace the crankshaft and thrust washer.
27. Check of crankshaft main journal oil clearance
(1) Gradually loosen the main bearing cap bolts over
three stages in the numerical sequence shown in the
figure. Remove the bearing cap bolts.
(2) With the main bearing cap bolts inserted into the bolt
holes of the main bearing cap, wiggle the bearing cap
back and forth. Remove the bearing cap together with
the lower bearing.
NOTE:
•
Keep the lower bearing fitted to the main bearing cap.
Arrange the removed main bearing caps in order.
(3) Lift off the crankshaft.
NOTE:
•
Be very careful not to allow the main bearings to be
mixed with the bearings of the other cylinders.
•
Remove the thrust washer.
•
If the main journal or crankshaft bearing exhibit dam-
