< PRECAUTION >[QR25DE]
PRECAUTIONS
4. Cover the serrated end of the valve with a large shop towel (A).
Strike the valve face end with a hammer, separating it into two
pieces.
5. Fill a bucket, such as a 20 (5-1/4 US gal, 4-3/8 Imp gal) oil can, with at least 10 (2-5/8 US gal, 2-1/4 lmp gal) of water.
Carefully place the already cut (serrated) valves into the water
one-at-a-time using a set of large tweezers and quickly move
away at least 2.7 m (9 ft).
6. The valves should be placed in a standing position as shown in the illustration to allow complete reaction. After the bubbling
action has subsided, additional valves can be placed into the
bucket allowing each subsequent chemical reaction to subside.
However, no more than 8 valves should be placed in the same
10 (2-5/8 US gal, 2-1/4 lmp gal) amount of water. The com-
plete chemical reaction may take as long as 4 to 5 hours.
Remove the valves using a set of large tweezers after the chem-
ical reaction has stopped. Afterwards, valves can be disposed
as ordinary scrap.
Precaution for Assembly and InstallationINFOID:0000000009460458
• Use torque wrench to tighten bolts or nuts.
• When tightening nuts and bolts, as a basic rule, equally tighten in several different steps starting with the
ones in center, then ones on inside and outside diagonally in this order. If the order of tightening is specified,
follow the specifications.
• Always replace the old with a new gas ket, packing, oil seal or O-ring.
• Thoroughly wash, clean, and air-blow each part. Carefully check oil or coolant passages for any restriction
and blockage.
• Avoid damaging sliding or mating surfaces. Completely remove foreign materials such as cloth lint or dust.
Before assembly, oil sliding surfaces well.
• Bleed the air trapped within the system after draining the coolant.
• Before starting engine, apply fuel pressure to fuel li nes with turning ignition switch ON (with engine stopped).
Then make sure that there are no leaks at fuel line connections.
• After repairing, start engine and increase engine speed to check coolant, fuel, oil, and exhaust systems for leakage or rattles.
Parts Requiring Angular TighteningINFOID:0000000009460459
• Use an angle wrench for the final tightening of the following engine parts.
- Cylinder head bolts
- Lower cylinder block bolts
- Connecting rod cap bolts
- Crankshaft pulley bolt (No angle wrench is required as the bolt flange is provided with notches for angular tightening)
• Do not use a torque value for final tightening.
• The torque value for these parts are for a preliminary step.
• Ensure thread and seat surfaces are clean and coated with engine oil.

DRIVE BELTS
2. Securely hold the hexagonal part (A) of drive belt auto-tensioner
(1) using suitable tool, and move in the direction of arrow (loos-
ening direction of tensioner).
WARNING:
Avoid placing hand in a locatio n where pinching may occur
if the holding tool accidentally comes off.
3. Insert a rod approximately 6 mm (0.24 in) in diameter through the rear of the drive belt auto-tensioner into retaining boss (B) to
lock drive belt auto-tensioner pulley.
NOTE:
Leave drive belt auto-tensioner pulley arm locked until drive belt
is installed again.
4. Loosen drive belt from drive belt auto-tensioner and then remove it from the other pulleys.
INSTALLATION
1. Install the drive belt onto all of the pulleys except for the drive belt auto-tensioner. Then install the drive
belt onto drive belt auto-tensioner last.
CAUTION:
Confirm belts are completely set on the pulleys.
2. Release drive belt auto-tensioner, and apply tension to drive belt.
WARNING:
Avoid placing hand in a location where pinching m ay occur if the holding tool accidentally comes
off.
3. Turn crankshaft pulley clockwise several times to equalize tension between each pulley.
4. Confirm the indicator is within the possible use range. Refer to EM-19, "Checking Drive Belts"
.
5. Install the fender protector side cover (RH). Refer to EXT-26, "FENDER PROTECTOR : Removal and
Installation".
Removal and Installation of Drive Belt Auto-tensionerINFOID:0000000009460471
REMOVAL
CAUTION:
The complete drive belt auto-tensioner must be replaced as a unit, including the pulley.
1. Remove the front RH wheel and tire assembly. Refer to WT-55, "Adjustment"
.

• Perform this inspection as follows after removal, inst
allation, or replacement of the camshaft or any valve-
related parts, or if there are any unusual engine conditions due to changes in valve clearance over time
(starting, idling, and/or noise).

Installation".
2. Remove the rocker cover using power tool. Refer to EM-45, "Removal and Installation"
.
3. Turn crankshaft pulley clockwise when viewed from front to align TDC identification mark (B) with timing indicator (A).
NOTE:
Do not confuse TDC mark (B) with paint marks (C).
4. At this time, check that the both intake and exhaust cam lobes of No. 1 cylinder face outside.
• If they do not face outside, turn crankshaft pulley once more.
5. Measure valve clearances with a feeler gauge at locations marked (X) in the table below.
• No.1 cylinder compression TDC.

ing liquid gasket.
• Do not fill the engine with oi l for at least 30 minutes after
the components are installed to allow the liquid gasket to
cure.
4. Install the lower oil pan to the upper oil pan and tighten the lower oil pan bolts to specification in the numerical order shown.
5. Installation of the remaining components is in the reverse order of removal.
