REPLACEMENT
1. REPLACE OVERSIZED (O/S) PISTONS FOR CYL-
INDER BORING
HINT:
Bore all the 8 cylinders to the oversized piston outside di-
ameter.
Replace all the piston rings with the ones to match the
oversized pistons.
(a) Keep 8 new O/S pistons.
O/S 0.50 piston diameter:
94.402 - 94.430 mm (3.7166 - 3.7177 in.)
HINT:
The shape of the piston varies for the LH and RH banks. The
LH piston is marked with ºLHº and º2Lº, the RH piston with ºRHº
and º2Rº.
(b) Using a micrometer, measure the piston diameter at right
angles to the piston pin center line, 30.75 mm (1.2106 in.)
from the piston head.
(c) Calculate the amount for each cylinder to be rebored as
follows:
Size to be rebored = P + C - H
P = Piston diameter
C = Piston clearance:
0.090 - 0.111 mm (0.0035 - 0.0044 in.)
H = Allowance for honing: 0.02 mm (0.0008 in.) or less
(d) Bore and hone the cylinders to calculated dimensions.
Maximum honing: 0.02 mm (0.0008 in.)
NOTICE:
Excess honing will destroy the finished roundness.
2. REPLACE CONNECTING ROD BUSHINGS
(a) Using SST and a press, press out the bushing.
SST 09222-30010
(b) Align the oil holes of a new bushing and the connecting
rod.
(c) Using SST and a press, press in the bushing.

(d) Using a pin hole grinder, hone the bushing to obtain the
standard specified clearance (See page EM-97) be-
tween the bushing and piston pin.
(e) Check the piston pin fit at normal room temperature. Coat
the piston pin with engine oil, and push it into the connect-
ing rod with your thumb.
3. REPLACE CRANKSHAFT FRONT OIL SEAL
HINT:
There are 2 methods ((a) and (b)) to replace the oil seal.
(a) If the oil pump is removed from the cylinder block:
(1) Using a screwdriver, pry out the oil seal.
(2) Using SST and a hammer, tap in a new oil seal until
its surface is flush with the oil pump body edge.
SST 09316-6001 1 (09316-00011)
(3) Apply MP grease to the oil seal lip.
(b) If the oil pump is installed to the cylinder block:
(1) Using a knife, cut off the oil seal lip.
(2) Using a screwdriver, pry out the oil seal.
NOTICE:
Be careful not to damage the crankshaft. Tape up the
screwdriver tip.

4. REPLACE CRANKSHAFT REAR OIL SEAL
HINT:
There are 2 methods ((a) and (b)) to replace the oil seal.
(a) If the rear oil seal retainer is removed from the cylinder
block:
(1) Using a screwdriver and hammer, tap out the oil
seal.
(2) Using SST and a hammer, tap in a new oil seal until
its surface is flush with the rear oil seal retainer
edge.
SST 09223-56010
(3) Apply MP grease to the oil seal lip.
(b) If the rear oil seal retainer is installed to the cylinder block:
(1) Using a knife, cut off the oil seal lip.
(2) Using a screwdriver, pry out the oil seal.
NOTICE:
Be careful not to damage the crankshaft. Tape up the
screwdriver tip.
(3) Apply MP grease to a new oil seal lip.
(4) Using SST and a hammer, tap in the oil seal until its
surface is flush with the rear oil seal retainer edge.
