1.9 Crankshaft End Play - Measure

(1) Verify the smooth rotation of the crankshaft.
(2) Apply a dial gauge probe to the rear end face of crank-
shaft.
(3) Using a bar, move the crankshaft fully to the front and
rear to read the each measurement. The end play is the
difference between the front and rear measurements.
If the value exceeds the standard value, inspect the
thrust plates and the crankshaft.
If the end play is less than the standard value, loosen
the rear most bearing cap bolts and move the crankshaft
back and forth, and measure the end play again.
(4) After tightening the rearmost main bearing cap to the
specified torque, measure the end play again to verify.
(5) Again, verify the crankshaft smooth rotation.
(6) Check that the all main bearing cap bolts are correctly
tightened.

1.10 Crankcase - Turn Over

Using a turnover machine, turn over the crankcase. When
the turnover machine is not available, hitch slings to the
crankcase using wood pieces and cloth pads, and raise the
crankcase with a hoist or crane. Then lay it on the wooden
block with its side facing downward. Then, change the sling
positions. Turn over the crankcase on the wooden blocks to
turn it to the normal position.
