Using a cylinder gauge, measure the cylinder bore diameter at
positions A, B and C in the thrust and axial directions.
Standard diameter:
Mark º1º74.000 - 74.010 mm (2.9134 - 2.9138 in.)
Mark º2º74.011 - 74.020 mm (2.9138 - 2.9142 in.)
Mark º3º74.021 - 74.030 mm (2.9142 - 2.9146 in.)
Maximum diameter:
74.23 mm (2.9224 in.)
If the diameter is greater than maximum, replace the cylinder
block.
5. REMOVE CYLINDER RIDGE
If the wear is less than 0.2 mm (0.008 in.), using a ridge reamer,
grind the top of the cylinder.
6. CLEAN PISTON

(c) Using a soft brush and solvent, thoroughly clean the pis-
ton.
NOTICE:
Do not damage the piston.
7. INSPECT PISTON OIL CLEARANCE
HINT:
There are 3 sizes of the standard piston diameter, marked º1º,
º2º and º3º accordingly. The mark is stamped on the piston top.
(a) Using a micrometer, measure the piston diameter at right
angles to the piston pin center line, 23 mm (0.91 in.) from
the piston head.
Piston diameter:
Mark º1º73.900 - 73.910 mm (2.9094 - 2.9098 in.)
Mark º2º73.910 - 73.920 mm (2.9098 - 2.9120 in.)
Mark º3º73.920 - 73.930 mm (2.9120 - 2.9106 in)
(b) Measure the cylinder bore diameter in the thrust direc-
tions (See step 4).
(c) Subtract the piston diameter measurement from the cylin-
der bore diameter measurement.
Standard oil clearance:
0.09 - 0.11 mm (0.0035 - 0.0043 in.)
Maximum oil clearance:
0.13 mm (0.0051 in.)
If the oil clearance is greater than maximum, replace all 4 pis-
tons. If necessary, replace the cylinder block.
HINT:
Use new cylinder block:
Use a piston with the same number mark as the cylinder bore
diameter marked on the cylinder block.

8. INSPECT PISTON RING GROOVE CLEARANCE
Using a feeler gauge, measure the clearance between new pis-
ton ring and the wall of the ring groove.
Ring groove clearance:
No.10.04 - 0.08 mm (0.0016 - 0.0031 in.)
No.20.03 - 0.07 mm (0.0012 - 0.0028 in.)
If the oil clearance is greater than maximum, replace the piston.
9. 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, 110 mm (4.33 in.) from the top of the
cylinder block.
(c) Using a feeler gauge, measure the end gap.
Standard end gap:
No.10.26 - 0.48 mm (0.0102 - 0.0189 in.)
No.20.36 - 0.57 mm (0.0142 - 0.0224 in.)
Oil (Side rail)0.13 - 0.50 mm (0.0051 - 0.0197 in.)
Maximum end gap:
No.11.07 mm (0.0421 in.)
No.21.02 mm (0.0402 in.)
Oil (Side rail)1.10 mm (0.0433 in.)
If the end gap is greater than maximum, replace the piston ring.
If necessary, replace the cylinder block.
10. INSPECT CONNECTING RODS
Using a rod aligner, check the connecting rod alignment.
Check for out-of-alignment.
Maximum out-of-alignment:
0.03 mm (0.0012 in.) per 100 mm (3.94 in.)
If out-of-alignment is greater than maximum, replace the con-
necting rod assembly.

Check for twist
Maximum twist:
0.05 mm (0.0020 in.) per 100 mm (3.94 in.)
If twist is greater than maximum, replace the connecting rod as-
sembly.
HINT:
If replacing the connection rods, replace the same number of
connecting rod bearings as that of new connecting rod caps.
11. INSPECT CRANKSHAFT FOR RUNOUT
(a) Place the crankshaft on V-blocks.
(b) Using a dial indicator, measure the circle runout at the
center journal.
Maximum circle runout: 0.06 mm (0.0024 in.)
If the circle runout is greater than maximum, replace the crank-
shaft.
12. INSPECT MAIN JOURNALS AND CRANK PINS
(a) Using a micrometer, measure the diameter of each main
journal and crank pin.
Main journal diameter:
STD49.985 - 50.000 mm (1.9679 - 1.9685 in.)
U/S 0.2549.745 - 49.755 mm (1.9585 - 1.9589 in.)
Crank pin diameter:
STD42.985 - 43.000 mm (1.6923 - 1.6929 in.)
U/S 0.2542.745 - 42.755 mm (1.6829 - 1.6833 in.)
If the diameter is not as specified, check the oil clearance (See
page EM-70).
If necessary, grind or replace the crankshaft.
(b) Check each main journal and crank pin for taper and out-
of-round as shown.
Maximum taper:
0.08 mm (0.0031 in.)
Maximum out-of-round:
0.07 mm (0.0028 in.)
If the taper and out-of-round is greater than maximum, replace
the crankshaft.
13. IF NECESSARY, GRIND AND HONE MAIN JOURNALS
AND/OR CRANK PINS
(a) Grind and hone the main journals and/or crank pins to the
finished undersized diameter (See procedure in step 2).
(b) Install new main journal and/or crank pin undersized
bearings.
