INSTALLATION
FRONT SIDE BELT
CAUTION:
^ When reusing the front side belt, wipe off any sand or water with a cloth.
^ Do not use the front side belt if there is any oil, grease or coolant on the belt.
^ Be careful when touching the belt. If the end face of the belt is rubbed by hand, you may receive injury from bared wires.
1) Wipe off any sand, dust, oil or water from the pulley grooves with a cloth.
2) Install the front side belt (C), and adjust the slider bolt (B) so as to obtain the specified belt tension.
3) Tighten the bolt (A).
Tightening torque: 25 Nm (2.5 kgf-m, 18.4 ft. lbs.)
4) Install the air intake duct.
5) Install the V-belt cover.
Tightening torque: 13 Nm (1.3 kgf-m, 9.6 ft. lbs.)
REAR SIDE BELT
CAUTION:
^ Always use new rear side belt.
^ Be careful that the new rear side belt does not come into contact with any oil, grease or coolant.
^ Be careful when touching the belt. If the end face of the belt is rubbed by hand, you may receive injury from bared wires.
^ When installing the rear side belt, always use the provided tools (belt stopper, belt guide, belt guide holder and bolt).
1) Wipe off any sand, dust, oil or water from the pulley grooves with a cloth.
2) Wipe off any oil, water, mud or rust attached to the front side of the crank pulley with a cloth.
3) Turn the crank pulley to the right slowly, until the crank pulley service hole near the top.
CAUTION: Never turn the crank pulley to the left.
4) Attach a new rear side belt on the A/C compressor pulley.
5) Insert the claw of the belt stopper (A) into the lower hole (B) on the compressor bracket as shown in the figure, and attach using bolt (C).
6) Mount the belt guide by matching to the belt line on the front side belt of the crank pulley.
7) Insert the belt guide holder into the crank pulley service hole so as to clamp the belt guide.
NOTE: The longer side of the belt guide holder is the upper side.
8) Turn the crank pulley slowly to the right, and set the belt guide at an approximately 45° position.
9) Place the rib face of the rear side belt into the grooves of the crank pulley, and sandwich the rear side belt with the belt guide holder.
CAUTION: When it is difficult to place the rear side belt to the crank pulley groove, pull out the belt guide holder half way, then place the rear side belt into the groove so that it comes in between the belt guide holder.
10) Place the tool through the loop of the rear side belt, and set on the crank pulley bolt.
11) While checking for the following, turn the crank pulley slowly to the right by approximately 90° and set the belt guide to the position shown in the figure.
CAUTION: When turning the crank pulley, always make sure that the belt guide does not slide off from the crank pulley groove.
1) The ribs of the rear side belt are properly riding on the grooves of the A/C compressor pulley.
2) The ribs of the rear side belt are properly riding on the grooves of the crank pulley.
3) The surface of the rear side belt is being pressed by the belt stopper.
4) The rear side belt is riding properly on the belt guide.
12) While checking for the following, turn the crank pulley slowly to the right by approximately 90° and set the belt guide to the position shown in the figure.
1) The rear side belt is not twisted.
2) The ribs of the rear side belt are properly riding on the grooves of the A/C compressor pulley.
3) The ribs of the rear side belt are properly riding on the grooves of the crank pulley.
4) The surface of the rear side belt is being pressed by the belt stopper.
5) The rear side belt is riding properly on the belt guide.
13) Turn the crank pulley slowly to the right, and attach the rear side belt.
CAUTION: Because there is a possibility of damage to the rear side belt, and the belt guide holder failing off, care must be taken to make sure that the total of steps 8), 11), 12), and 13) does not exceed 330°.
14) Remove the belt guide and belt guide holder from the crank pulley.
15) Remove the belt stopper from the compressor bracket.
CAUTION: Make sure to remove the belt stopper, as leaving it on can cause smoke, flames or belt breakage.
16) Make sure that the belt ribs are properly riding on the grooves of the pulleys, and turn the crank pulley slowly to the right twice to break in the rear side belt.
17) Discard the provided tools (belt stopper, belt guide, belt guide holder, bolt).
18) Install the front side belt.
INSPECTION
FRONT SIDE BELT
1) Replace the front side belt, if cracking, fraying or wear is found.
2) Check the front side belt tension and adjust it if necessary by changing the generator installing position.
Front side belt tension (when using a belt tension gauge):
When installing new parts 640 - 780 N (65 - 80 kgf, 144 - 175 lbs.)
At inspection 490 - 640 N (50 - 65 kgf, 110 - 144 lbs.)
Front side belt tension (when not using a belt tension gauge):
When installing new parts 7 - 9 mm (0.276 - 0.354 inch)
At inspection 9 - 11 mm (0.354 - 0.433 inch)
REAR SIDE BELT
If cracks, fraying or wear is found, and when abnormal noise is produced, replace the rear side belt.
NOTE: Because the rear side belt is a stretch type belt, it is not necessary to check deflection and tension.
