DRIVE BELT ON-VEHICLE INSPECTION


  1. TILT UP CAB

    CAUTION:


    • Make sure that the vehicle is on a level surface before tilting the cab up.

    • Make sure that all the doors are closed before tilting the cab up.

    • Make sure that nobody is inside or near the cab when tilting it up.

    • Be sure to have 2 people tilt the cab up when a heavy object such as a roof rack or cargo carrier is installed to the cab.

    • Be sure to remove anything set on top of the cab before tilting it up.

    • Make sure that the cab is securely locked in place after it is tilted up.

    • Make sure that there are no tools, cloths, etc. left in the engine room before tilting the cab back down.

    • Make sure that the cab is securely locked in place after tilting it back down.

  2. INSPECT V BELT


    1. Check the V belt for wear, cracks or other signs of damage.

      If any of the following defects is found, replace the V belt.


      • The V belt is cracked.

      • The V belt is worn out to the extent that the cords are exposed.

      • The V belt has chunks missing from the ribs.

    2. Check that the V belt fits properly in the ribbed grooves.

      Tech Tips

      Check with your hand to confirm that the V belt has not slipped out of the groove on the bottom of the pulley. If it has slipped out, replace the V belt. Install the V belt correctly.

      *1 Fan Pulley
      *2 Generator
      *3 Crankshaft Pulley

      Check the fan and generator V belt deflection.

      Standard Deflection
      Item Specified Condition
      New belt 10.5 to 12.5 mm (0.413 to 0.492 in.)
      Used belt 12 to 13 mm (0.472 to 0.512 in.)

      Note


      • Check the V belt deflection at the specified point.

      • When inspecting a V belt which has been used for over 5 minutes, use the used V belt specifications.

      Tech Tips

      When inspecting the V belt deflection, apply 98 N (10 kgf, 22 lbf) of tensile force to it.

      *1 Idler Pulley
      *2 A/C Compressor
      *3 Crankshaft Pulley

      Check the No. 1 V (cooler compressor to crankshaft pulley) belt deflection.

      Standard Deflection
      Item Specified Condition
      New belt 7 to 9 mm (0.276 to 0.354 in.)
      Used belt 8.5 to 10 mm (0.335 to 0.394 in.)

      Note


      • Check the V belt deflection at the specified point.

      • When inspecting a V belt which has been used for over 5 minutes, use the used V belt specifications.

      Tech Tips

      When inspecting the V belt deflection, apply 98 N (10 kgf, 22 lbf) of tensile force to it.
