INSPECTION
1. REMOVE GASKET MATERIAL
Using a gasket scraper, remove all the gasket material from the
top surface of the cylinder block.
2. CLEAN CYLINDER BLOCK
Using a soft brush and solvent, thoroughly clean the cylinder
block.
3. INSPECT TOP SURFACE OF CYLINDER BLOCK FOR
FLATNESS
Using a precision straight edge and feeler gauge, measure the
surfaces contacting the cylinder head gasket for warpage.
Maximum warpage:
0.05 mm (0.0020 in.)
If warpage is greater than maximum, replace the cylinder block.
4. INSPECT CYLINDER FOR VERTICAL SCRATCHES
Visually check the cylinder for vertical scratches.
If deep scratches are present, rebore all the 6 cylinders. If nec-
essary, replace the cylinder block.
5. INSPECT CYLINDER BORE DIAMETER
HINT:
There are 3 sizes of the standard cylinder bore diameter,
marked ”1”, ”2” and ”3” accordingly. The mark is stamped on the
top of the cylinder block.

10. INSPECT PISTON RING END GAP
(a) Insert the piston ring into the cylinder bore.
(b) Using a piston, push the piston ring a little beyond the bot-
tom of the ring travel, 115 mm (4.53 in.) from the top of the
cylinder block.
(c) Using a feeler gauge, measure the ring end gap.
Standard ring end gap:
No.10.300 − 0.500 mm (0.0118 − 0.0197 in.)
No.20.400 − 0.600 mm (0.0157 − 0.0236 in.)
Oil (Side rail)0.150 − 0.550 mm (0.0059 − 0.0217 in.)
Maximum ring end gap:
No.11.100 mm (0.0433 in.)
No.21.200 mm (0.0472 in.)
Oil (Side rail)1.150 mm (0.0453 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.
11. INSPECT PISTON PIN FIT
At 60°C (140°F), you should be able to push the piston pin into
the piston pin hole with your thumb.
12. INSPECT CONNECTING ROD ALIGNMENT
Using a rod aligner and feeler gauge, check the connecting rod
alignment.
Check for bend.
Maximum bend:
0.05 mm (0.0020 in.) per 100 mm (3.94 in.)
If bend is greater than maximum, replace the connecting rod as-
sembly.
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.

(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.
15. INSPECT CONNECTING ROD BOLTS
(a) Install the cap nut to the connecting rod bolt. Check that
the rod cap nut can be turned easily by hand to the end
of the thread.
(b) If the cap nut cannot be turned easily, measure the outer
diameter of the compressed thread with vernier calipers.
Standard outer diameter:
7.860 − 8.000 mm (0.3094 − 0.3150 in.)
Minimum outer diameter: 7.600 mm (0.2992 in.)
HINT:
If the location of this area cannot be judged by visual inspection,
measure the outer diameter at the location shown in the illustra-
tion.
If the outer diameter is less than minimum, replace the connect-
ing rod and rod cap nut as a set.
16. CYLINDER BORING
HINT:
Bore all the 6 cylinders for the oversized piston outside di-
ameter.
Replace all the piston rings with ones to match the over-
sized pistons.
(a) Keep the oversized pistons.
Oversized piston diameter:
O/S 0.50: 93.856 − 93.886 mm (3.6951 − 3.6963 in.)
(b) Calculate amount to the bore cylinders.
(1) Using a micrometer, measure the piston diameter at
right angles to the piston pin center line, 26 mm
(1.02 in.) from the piston head.

(2) Calculate the amount of each cylinder is to be re-
bored as follows:
Size to be rebored = P + C − H
P = Piston diameter
C = Piston oil clearance
0.134 − 0.154 mm (0.0053 − 0.0060 in.)
H = Allowance for honing
0.02 mm (0.0008 in.) or less
(3) C.Bore and hone cylinder to calculated dimensions
Maximum honing:
0.02 mm (0.0008 in.)
NOTICE:
Excess honing will destroy the finished roundness.
17. INSPECT CRANKSHAFT FOR RUNOUT
(a) Place the crankshaft on V−blocks.
(b) Using a dial indicator, measure the circle runout at the
No.2 and No.3 journals.
Maximum circle runout:
0.06 mm (0.0024 in.)
If the circle runout is greater than maximum, replace the crank-
shaft.
18. INSPECT MAIN JOURNALS AND CRANK PINS
(a) Using a micrometer, measure the diameter of each main
journal and crank pin.
Main journal diameter:
STD63.985 − 64.000 mm (2.5191 − 2.5197 in.)
U/S 0.2563.745 − 63.755 mm (2.5096 − 2.5100 in.)
Crank pin diameter:
STD54.987 − 55.000 mm (2.1648 − 2.1654 in.)
U/S 0.2554.745 − 54.755 mm (2.1553 − 2.1557 in.)
If the diameter is not as specified, check the oil clearance (See
page EM−84).
(b) Check each main journal and crank pin for taper and out−
of−round as shown.
Maximum taper and out−of−round:
0.02 mm (0.0008 in.)
If the taper or out−of−round is greater than maximum, grind or
replace the crankshaft.
