(c) Inspect the piston ring end gap.
(1) Insert the piston ring into the cylinder bore.
(2) Using a piston, push the piston ring a little beyondthe bottom of the ring travel, 125 mm (4.92 in.) from
the top of the cylinder block.
(3) Using a feeler gauge, measure the end gap.
Standard end gap:
No. 10.300 − 0.520 mm (0.0118 − 0.0205 in.)
No. 20.450 − 0.670 mm (0.0177 − 0.0264 in.)
Oil (Side rail)0.150 − 0.520 mm (0.0059 − 0.0205 in.)
Maximum end gap:
No. 11.12 mm (0.0441 in.)
No. 21.17 mm (0.0461 in.)
Oil (Side rail)1.12 mm (0.0441 in.)
If the end gap is greater than maximum, replace the piston ring.
If the end gap is greater than maximum, even with a new piston
ring, rebore all the 6 cylinders or replace the cylinder block.
(d) Inspect the piston pin fit.
At 80 − 90°C (176 − 194°F), you should be able to push
the piston pin into the piston pin hole with your thumb.
(e) Using a rod aligner and feeler gauge, check the connect- ing rod alignment.
(1) Check for out−of−alignment.
Maximum out−of−alignment:
0.05 mm (0.0020 in.) per 100 mm (3.94 in.)
If out− of−alignment is greater than maximum, replace the con-
necting rod assembly.

(2) Check for twist
Maximum twist:
0.15 mm (0.0059 in. ) per 100 mm (3.94 in.)
If twist is greater than maximum, replace the connecting rod as-
sembly.
(f) Inspect the piston pin oil clearance. (1) Using a caliper gauge, measure the inside diameter
of the connecting rod bushing.
Bushing inside diameter:
26.008 − 26.020 mm (1.0239 − 1.0244 in.)
(2) Using a micrometer, measure the piston pin diame-
ter.
Piston pin diameter:
26.000 − 26.012 mm (1.0236 − 1.0241 in.)
(3) Subtract the piston pin diameter measurement from
the bushing inside diameter measurement.
Standard oil clearance:
0.004 − 0.012 mm (0.0002 − 0.0005 in.)
Maximum oil clearance: 0.05 mm (0.0020 in.)
If the oil clearance is greater than maximum, replace the bush-
ing. If necessary, replace the piston and piston pin as a set (See
page EM−99 ).
(g) Inspect the connecting rod bolts. Install the cap nut to the connecting rod bolt. Check that
the cap nut can be turned easily by hand to the end of the
thread.
If the cap nut cannot be turned easily, measure the outside di-
ameter of the connecting rod bolt with vernier calipers. Standard outside diameter:
8.40 − 8.60 mm (0.3307 − 0.3386 in.)
Minimum outside diameter: 8.00 mm (0.3150 in.)

(b) If the timing chain cover is installed to the cylinder block:
(1) Using a screwdriver, pry out the oil seal.
NOTICE:
Be careful not to damage the crankshaft. Tape the screw-
driver tip.
(2) Apply MP grease to a new oil seal lip.
NOTICE:
Do not let foreign matter get onto the lip of the oil seal.
(3) Using SST and a hammer, tap in the oil seal until its
surface is flush with the timing chain cover edge.

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.
NOTICE:
Be careful not to damage the crankshaft. Tape the screw-
driver tip.
