Tension check
Note: under «old belt» means a belt that has been on the engine for more than 5 minutes.
1. With a force of 98 N (10 kg) in the center of the belt (A) between the compressor pulleys and the crankshaft, check the deflection of the drive belt.
Deflection (tension) belt:
- new belt - 3.3-3.7mm (63±5N);
- belt used - 4.2-4.7 mm (36±5 N);
- after running in - ≈8 mm (25-50 N).
Tension adjustment
Attention: the diesel engine compressor drive belt cannot be adjusted.
2. Loosen the screw (IN) tension device.
3. Turning the adjusting screw (WITH) adjust the belt tension, then tighten the tensioner screw.
4. Recheck belt tension.
