REMOVAL
1. REMOVE FRONT WHEEL RH
2. REMOVE FRONT FENDER APRON SEAL RH (See
page EM-26)

(b) While turning the belt tensioner counterclockwise,
align with its holes, and then insert the 5 mm bi-
hexagon wrench into the holes to fix the V-ribbed
belt tensioner.
INSPECTION
1. INSPECT V-RIBBED BELT
(a) Visually check the V-ribbed belt for excessive wear,
frayed cords, etc.
If any defect has been found, replace the V-ribbed
belt.
HINT:
Cracks on the rib side of a V-ribbed belt are
considered acceptable.
If the drive belt has chunks missing from its ribs, it
should be replaced.
HINT:
• A "new belt" is a belt which has been used for
less than 5 minutes with the engine running.
• A "used belt" is a belt which has been used for 5
minutes or more with the engine running.
2. INSPECT V-RIBBED BELT TENSIONER ASSEMBLY
(a) Check that nothing gets caught in the tensioner by
turning it clockwise and counterclockwise.
If a malfunction exitsts, replace the tensioner.

INSTALLATION
1. INSTALL V-RIBBED BELT
(a) Install the V-ribbed belt.
(b) Using SST, turn the belt tensioner counterclockwise
and remove the bar.
SST 09249-63010
(c) If it is difficult to install the V-ribbed belt, perform the
following procedure:
(1) Put the V-ribbed belt on every pulley except the
tensioner pulley as shown in the illustration.
(2) While releasing the belt tension by turning the
belt tensioner counterclockwise, put the V-
ribbed belt on the tensioner pulley.
NOTICE:
• Put the backside of the V-ribbed belt on
the tensioner pulley and idler pulley.
• Check that the V-ribbed belt is properly
set to each pulley.
(3) After installing the V-ribbed belt, check that it
fits properly in the ribbed grooves. Confirm that
the belt has not slipped out of the grooves on
the bottom of the crank pulley by hand.
