(b) MAHLE made:
(1) Using a micrometer, measure the piston diameter at
right angles to the piston pin center line, 41.2 mm
(1.622 in.) from the piston head.
Piston diameter:
87.453 ± 87.467 mm (3.4430 ± 3.4436 in.)
(2) Measure the cylinder bore diameter in the thrust
directions. (See inspection in cylinder block)
(3) Subtract the piston diameter measurement from the
cylinder bore diameter measurement.
Standard oil clearance:
0.033 ± 0.059 mm (0.0013 ± 0.0023 in.)
Maximum oil clearance: 0.08 mm (0.0031 in.)
If the oil clearance is greater than maximum, replace all the 6
pistons. If necessary, replace the cylinder block.
HINT:
The shape of the piston varies for the RH and LH banks. The
RH piston is marked with ºRº, the LH piston with ºLº.
10. INSPECT PISTON RING GROOVE CLEARANCE
Using a feeler gauge, measure the clearance between new pis-
ton right and the wall of the ring groove.
Ring groove clearance:
No.10.020 ± 0.070 mm (0.0008 ± 0.0028 in.)
No.20.020 ± 0.060 mm (0.0008 ± 0.0024 in.)
If the clearance is not as specified, replace the piston.
11. 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, 105 mm (4.13 in.) from the top of the
cylinder block.
(c) Using a feeler gauge, measure the end gap.
Standard end gap:
No.10.25 ± 0.35 mm (0.0098 ± 0.0138 in.)
No.20.35 ± 0.45 mm (0.0138 ± 0.0177 in.)
Oil (Side rail)0.15 ± 0.40 mm (0.0059 ± 0.0157 in.)
Maximum end gap:
No.10.95 mm (0.0374 in.)
No.21.05 mm (0.0413 in.)
Oil (Side rail)1.00 mm (0.0394 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, replace the cylinder block.
12. 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.
13. INSPECT CONNECTING ROD ALIGNMENT
Using a rod aligner and feeler gauge, check the connecting rod
alignment.

Check for out±of±alignment.
Maximum out±of±alignment:
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.
14. INSPECT PISTON PIN OIL CLEARANCE
(a) Using a caliper gauge, measure the inside diameter of the
connecting rod bushing.
Bushing inside diameter:
22.005 ± 22.014 mm (0.8663 ± 0.8667 in.)

(b) Using a micrometer, measure the piston pin diameter.
Piston pin diameter:
21.997 ± 22.006 mm (0.8660 ± 0.8664 in.)
(c) Subtract the piston pin diameter measurement from the
bushing inside diameter measurement.
Standard oil clearance:
0.005 ± 0.011 mm (0.0002 ± 0.0004 in.)
Maximum oil clearance: 0.05 mm (0.0020 in.)
15. INSPECT CONNECTING ROD BOLTS
Using vernier calipers, measure the tension portion diameter of
the bolt.
Standard diameter: 7.2 ± 7.3 mm (0.284 ± 0.287 in.)
Minimum diameter: 7.0 mm (0.276 in.)
If the diameter is less than minimum, replace the bolt.
16. INSPECT CRANKSHAFT FOR CIRCLE RUNOUT
(a) Place the crankshaft on V±blocks.
(b) Using a dial indicator, measure the circle runout, as
shown in the illustration.
Maximum circle runout: 0.06 mm (0.0024 in.)
If the circle runout is greater than maximum, replace the crank-
shaft.
17. INSPECT MAIN JOURNALS AND CRANK PINS
(a) Using a micrometer, measure the diameter of each main
journal and crank pin.
Main journal diameter:
60.988 ± 61.000 mm (2.4011 ± 2.4016 in.)
Crank pin diameter:
52.992 ± 53.000 mm (2.0862 ± 2.0866 in.)
If the diameter is not as specified, check the oil clearance.
(See page EM±83)
If necessary, replace the crankshaft.
(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 and out±of±round is greater than maximum, replace
the crankshaft.
