CYLINDER BLOCK
 If there is stamped mark on ring, mount it with marked side up.
NOTE:
If there is no stamp on ring, no specific orientation is required
for installation.
 Position each ring with the gap as shown in the figure referring
to the piston front mark (D).
 Check the piston rings side clearance. Refer to EM-119, "
Inspection".
11. Install connecting rod bearings to connecting rod and connecting rod bearing cap.
CAUTION:
Be careful not to drop connecting rod bearing, and to scratch the surface.
 Before installing connecting rod bearings, apply engine oil to the bearing surface (inside). Do not apply
engine oil to the back surface, but thoroughly clean it.
 When installing, align connecting rod bearing stopper protru-
sion (B) with cutout (C) of connecting rod and connecting rod
bearing cap to install.
 Ensure the oil hole (A) on connecting rod and that on the cor-
responding bearing are aligned.
12. Install piston and connecting rod assembly to crankshaft.
 Position crankshaft pin corresponding to connecting rod to be installed onto the bottom dead center.
 Apply engine oil sufficiently to the cylinder bore, piston and crankshaft pin journal.
 Match the cylinder position with the cylinder number on connecting rod to install.
 Be sure that front mark on piston crown is facing front of engine.
 Using a piston ring compressor [SST: EM03470000 (J8037)]
(A) or suitable tool, install piston with the front mark on the pis-
ton crown facing the front of the engine.
CAUTION:
Be careful not to damage the cylinder wall and crankshaft
pin, resulting from an interference of the connecting rod big
end.Stamped mark: VQ25DE VQ35DE

 Check pin diameter grade (“0”, “1” or “2”) on front of crankshaft,
and select connecting rod bearing of the same grade.
NOTE:
There is no grading for connecting rod big end diameter.
WHEN CONNECTING ROD AND CRANKSHAFT ARE REUSED
1. Measure the connecting rod big end diameter. Refer to EM-119, "Inspection".
2. Check that the connecting rod big end diameter is within the standard value.
3. Measure the crankshaft pin journal diameter. Refer to EM-119, "
Inspection".
4. Determine the grade of crankshaft pin diameter grade by corresponding to the measured dimension in
“Crankshaft pin journal diameter” column of “CONNECTING ROD BEARING SELECTION TABLE”.
5. Select connecting rod bearing of the same grade.

installed, and grind crankshaft pin so that the connecting rod bearing oil clearance satisfies the standard.
CAUTION:
In grinding crankshaft pin to use undersize bearings, keep the
fillet R (A) [1.5 - 1.7 mm (0.059 - 0.067 in)].

CUSTOMER INTERVIEW
Interview the customer if possible, to determine the conditions that exist when the noise occurs. Use the Diag-
nostic Worksheet during the interview to document the facts and conditions when the noise occurs and any of
the customer's comments; refer to EXT-6, "
Diagnostic Worksheet". This information is necessary to duplicate
the conditions that exist when the noise occurs.
• The customer may not be able to provide a detailed description or the location of the noise. Attempt to obtain
all the facts and conditions that exist when the noise occurs (or does not occur).
 If there is more than one noise in the vehicle, always diagnose and repair the noise that the customer is con-
cerned about. This can be accomplished by a test drive with the customer.
 After identifying the type of noise, isolate the noise in terms of its characteristics. The noise characteristics
are provided so the customer, service adviser and technician are all speaking the same language when
defining the noise.
 Squeak – (Like tennis shoes on a clean floor)
Squeak characteristics include the light contact/fast movement/brought on by road conditions/hard surfaces
= higher pitch noise/softer surfaces = lower pitch noises/edge to surface = chirping
 Creak – (Like walking on an old wooden floor)
Creak characteristics include firm contact/slow movement/twisting with a rotational movement/pitch depen-
dent on materials/often brought on by activity.
 Rattle – (Like shaking a baby rattle)
Rattle characteristics include the fast repeated contact/vibration or similar movement/loose parts/missing
clip or fastener/incorrect clearance.
 Knock – (Like a knock on a door)
Knock characteristics include hollow sounding/sometimes repeating/often brought on by driver action.
 Tick – (Like a clock second hand)
Tick characteristics include gentle contacting of light materials/loose components/can be caused by driver
action or road conditions.
 Thump – (Heavy, muffled knock noise)
Thump characteristics include softer knock/dead sound often brought on by activity.
 Buzz – (Like a bumble bee)
Buzz characteristics include high frequency rattle/firm contact.
 Often the degree of acceptable noise level varies depending upon the person. A noise that is judged accept-
able may be very irritating to the customer.
 Weather conditions, especially humidity and temperature, may have a great effect on noise level.

 When resin tube or hard tube (or the equivalent) is
replaced, also replace retainer with new one.
 To keep the connecting portion clean and to avoid dam-
age and foreign materials, cover them completely with
plastic bags (A) or something similar.
