G2M0106
1. General Precautions
1) Before disassembling engine, place it on ST3.
ST1 498457000 ENGINE STAND ADAPTER RH
ST2 498457100 ENGINE STAND ADAPTER LH
ST3 499817000 ENGINE STAND
2) All parts should be thoroughly cleaned, paying special
attention to the engine oil passages, pistons and bearings.
3) Rotating parts and sliding parts such as piston, bearing
and gear should be coated with oil prior to assembly.
4) Be careful not to let oil, grease or coolant contact the
timing belt, clutch disc and flywheel.
5) All removed parts, if to be reused, should be reinstalled
in the original positions and directions.
6) Gaskets and lock washers must be replaced with new
ones. Liquid gasket should be used where specified to
prevent leakage.
7) Bolts, nuts and washers should be replaced with new
ones as required.
8) Even if necessary inspections have been made in
advance, proceed with assembly work while making
rechecks.

B: INSPECTION
1. TIMING BELT
1) Check timing belt teeth for breaks, cracks, and wear. If
any fault is found, replace belt.
2) Check the condition of back side of belt; if any crack is
found, replace belt.
CAUTION:
Be careful not to let oil, grease or coolant contact
the belt. Remove quickly and thoroughly if this hap-
pens.
G2M0115
Do not bend the belt sharply.
Bending radius: h
60 mm (2.36 in) or more
2. BELT TENSION ADJUSTER
1) Visually check oil seals for leaks, and rod ends for
abnormal wear or scratches. If necessary, replace belt ten-
sion adjuster.
CAUTION:
Slight traces of oil at rod’s oil seal does not indicate a
problem.
2) While holding tensioner with both hands, push the rod
section against floor or wall ensuring the rod section will
react as follows:
(1) When applying a force of 147 N (15 kg, 33 lb), the
rod section should not sink.
(2) When applying a force of 147 to 490 N (15 to 50 kg,
33 to 110 lb), the rod section should maintain a projec-
tionally acting force and should not sink within 8.5 sec-
onds.
