2. REPLACE OVERSIZED (O/S) PISTONS FOR CYLIN-
DER BORING
HINT:
Bore all the 6 cylinders for the O/S piston outside diame-
ter.
Replace all the piston rings with ones to match the O/S
pistons.
(a) Keep 6 new O/S pistons. O/S piston diameter:
O/S 0.50100.450 − 100.480 mm (3.9547 − 3.9559 in.)
O/S 1.00100.950 − 100.980 mm (3.9744 − 3.9756 in.)
(b) Using a micrometer, measure the piston diameter at right
angles to the piston pin center line, 42 mm (1.65 in.) from
the piston head.
(c) Calculate the amount of each cylinder is to be rebored as
follows:
Size to be rebored = P + C − H
P = Piston diameter
C = Piston oil clearance
0.040 − 0.060 mm (0.0016 − 0.0024 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.
3. REPLACE CRANKSHAFT FRONT OIL SEAL
HINT:
There are 2 methods ((a) and (b)) to replace the oil seal.
(a) If the timing chain cover is removed from the cylinder block:
(1) Using a screwdriver and a hammer, tap out the oilseal.
(2) Using SST and a hammer, tap in a new oil seal until
its surface is flush with the timing chain cover edge.
SST 09316−60011 (09316 −00011, 09316−00051)
(3) Apply MP grease to the oil seal lip.
NOTICE:
Do not let foreign matter get onto the lip of the oil seal.

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 a 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 edge.
SST 09223−15030, 09950 −70010 (09951−07150)
NOTICE:
Do not let foreign matter get onto the lip of the oil seal.
(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.
