Compressor Drive Belt Inspection and Adjustment (M13A Model)
Inspection
• Check belt for wear and cracks, and replace as required.
• Check belt tension by measuring how much it deflects when pushed at intermediate point between compressor pulley (1) and crankshaft pulley (2) with about 100 N (10 kg, 22 lb) force.
If belt tension is out of above specification, adjust belt tension according to the following procedures.
Deflection of compressor drive belt
“a”: 6 – 9 mm (0.24 – 0.35 in.)
Adjustment
For Vehicle with P/S
1) Loosen tension pulley bolts (3) and set hexagon wrench (4) to hexagon hole.
2) Turn tension pulley (5) counterclockwise by hexagon wrench in order to obtain specified tension.
3) Tighten tension pulley bolts (3) to specified torque.
For Vehicle without P/S
1) Loosen tension pulley tightening nut (3).
2) Adjust belt tension by tighten or loosen tension pulley adjusting bolt (4) in order to obtain above specified tension.
3) Tighten tension pulley tightening nut (3).
