Checking and adjusting the tension of the power steering pump and air conditioning compressor drive belt (Mitsubishi Pajero 4)

1. Using a special tool, check the belt tension at the point midway between the crankshaft pulley and the power steering pump.

2. Press the belt at this point with a force of 98 N, measure the belt deflection and compare it with the nominal value.

Nominal value:

Indicator	When checking	When a used belt is installed	When a new belt is installed
Tension, N	392 - 588	441 - 539	637 - 833
Sag (reference value), mm	11,7-15,3	12,5-14,3	8,8-11,0

3. If the measured values of belt tension and deflection differ from the nominal values, then adjust using the following method.

1) Loosen the tensioner pulley lock nut.

2) Adjust the belt tension (deflection) with the adjusting bolt.

3) Tighten the lock nut to 25 Nm.

4) Check the belt tension and deflection and, if necessary, repeat the adjustment procedure.

Note: The check is performed after turning the crankshaft clockwise one or more revolutions (rotation to the right).
