INSPECT FAN AND GENERATOR V BELT
INSPECT V-RIBBED BELT TENSIONER ASSEMBLY
INSPECT VISCOUS HEATER V BELT
Drive Belt -- On-Vehicle Inspection |
1. INSPECT FAN AND GENERATOR V BELT |
Check the belt for wear, cracks or other signs of damage.
If any of the following defects is found, replace the fan and generator V belt.
- The fan and generator V belt is cracked.
- The fan and generator V belt is worn out to the extent that the cords are exposed.
- The fan and generator V belt has chunks missing from the ribs.
Check that the fan and generator V belt fits properly in the ribbed grooves.
- HINT:
- Check with your hand to confirm that the fan and generator V belt has not slipped out of the grooves on the bottom of the pulley. If it has slipped out, replace the fan and generator V belt. Install a new fan and generator V belt correctly.

2. INSPECT V-RIBBED BELT TENSIONER ASSEMBLY |
Remove the fan and generator V belt. (LandCruiser RM00000122Y00LX.html)
Check that nothing gets caught in the V-ribbed belt tensioner assembly by turning it clockwise and counterclockwise.
If a malfunction exists, replace the V-ribbed belt tensioner assembly.
Turn the pulley, and check that the tensioner bearing moves smoothly and quietly.
If necessary, replace the tensioner pulley.

3. INSPECT VISCOUS HEATER V BELT |
Check the belt for wear, cracks or other signs of damage.
If any of the following defects is found, replace the viscous heater V belt.
- The viscous heater V belt is cracked.
- The viscous heater V belt is worn out to the extent that the cords are exposed.
- The viscous heater V belt has chunks missing from the ribs.
Check that the viscous heater V belt fits properly in the ribbed grooves.
- HINT:
- Check with your hand to confirm that the viscous heater V belt has not slipped out of the grooves on the bottom of the pulley. If it has slipped out, replace the viscous heater V belt. Install a viscous heater V belt correctly.

Using a belt tension gauge, check the viscous heater V belt tension.
- Standard Compressor Tension:
Item
| Specified Condition
|
New belt
| 382 to 618 N (39 to 63 kgf, 85.9 to 138.9 lbf)
|
Used belt
| 282 to 478 N (29 to 49 kgf, 63.4 to 107.5 lbf)
|
- HINT:
- When inspecting a viscous heater V belt which has been used for over 5 minutes, use the used viscous heater V belt specifications.
If the belt tension is not specified, adjust the viscous heater V belt.
