5. CHECK CRANKSHAFT THRUST CLEARANCE
Using a dial indicator, measure the thrust clearance
while prying the crankshaft back and forth with a
screwdriver.
Standard thrust clearance:
0.020 – 0Z20 mm (0.0008 – 0.0087 in.)
Maximum thrust clearance:
0.30 mm (0.0118 in.)
If the thrust clearance is greater than maximum, re–
place the thrust washers as a set.
Thrust washer thickness:
2.440 – 2.490 mm (0.0961 – 0.0980 in.)
6. INSTALL PISTON AND CONNECTING ROD
ASSEMBLIES
(a) Cover the connecting rod bolts with a short piece of
hose to protect the crankshaft from damage.
(b) Using a piston ring compressor, push the correctly
numbered piston and connecting rod assemblies into
each cylinder with the front mark of the piston facing
forward.
NOTICE: The shape of the piston varies for the RH and LH
banks. The RH piston is marked with ”R”, The LH piston
with ”L”.
(d) Retighten the main bearing cap bolts 90 in the nu–
merical order shown.
(e) Check that the painted mark is now at a 90 angle to
the front.
