Cylinder block
2. Check the connecting rods.
1) When reinstalling, make sure that cylinder numbers
put on the connecting rod and cap at disassembly
match. When a new connecting rod is installed, make
sure that the notches for holding the bearing in place
are on the same side.
2) Replace the connecting rod if it is damaged on the
thrust faces at either end. Also if step wear or a
severely rough surface of the inside diameter of the
small end is apparent, the rod must be replaced as
well.
3) Using a connecting rod aligning tool, check the rod
for bend and twist. If the measured value is close to
the repair limit, correct the rod by a press. Any
connecting rod that has been severely bent or
distorted should be replaced.
Crankshaft
1. Check the crankshaft bearing oil clearance.
1) To check main bearing-to-journal oil clearance,
remove the bed plate and lower bearings.
2) Clean each main journal and lower bearing with a
clean shop towel.
3) Place one strip of plastic gauge across each main
journal.
4) Reinstall the lower bearings and bed plate, and
then tighten the bolts.

5) Tighten the No.18, 20, 21 bolts in its number order
(18
→20→21) with the specified torque.
Tightening Torque:
29.4 ~ 33.3Nm (3.0 ~ 3.4kgf.m, 21.7 ~ 24.6lb-ft)
6) Tighten the No.1~16 bolts in two steps with the
specified torque and angle below.
Tightening Torque:
61.8 ~ 65.7Nm (6.3 ~ 6.7kgf.m, 45.6 ~ 48.5lb-ft) – 1st
step 120° ~ 124° - 2nd step
7) Loosen the bolts No. 18, 20 and 21.
8) Tighten the No.17~25 bolts with the specified
