3. Compressor belt
Remove the protective cover. Undo the nut (1) enough
so the belt slackens off. Tension the belt by tightening
the domed nut (2) on the tensioner screw to 35–40
Nm. Use a torque wrench and a suitable socket. Lock
the tensioner screw with the nut (1).
4. Servo pump belt
Undo the fixing screw (1). Tension the belt with the
adjustment screw (2), so that the belt can be pressed
down about 10 mm (3/8") between the pulleys, using
normal thumb pressure. Tighten the screw (1).
Replacement
Slacken belt off so that it can be removed. Clean off
the pulley grooves. Install the new belt. Adjust as
above. Check belt tension again after a few hours' op-
eration.
