7.10 Belt Drive Compressor
Remove the belt guard only when the engine is at a standstill and the key of the ignition/
starter switch is removed. See Safety Off Position as described in Chapter 2.
1. Remove the belt guard.
2. Loosen the compressor fixing nuts (1) and
release the belt tension by reducing the
distance between the belt pulleys using
the adjuster screws (2).
3. Insert the V-belt in the V-belt pulley groove
manually without forcing the belt.
4. Tension the V-belt by increasing the
distance between the belt pulleys using
the adjuster screws.
5. Tighten the fixing nuts.
6. Replace the belt guard.
7.11 Belt Tension Compressor
To achieve a maximum power transfer and live time the correct setting of the belt tension is
essential. Often belts are set with the wrong tension and fail before normal service time. Check
the correct pre-tension (3) by pressing down the belt. The distance the belt can be pressed down
should be 3-4 mm.
7.12 Taper-Lock Bushes
Taper locks are used to shrink-fit hubs on shafts.
Mounting and demounting only requires a screw
driver DIN 911 (Allen key). Tightening and
loosening is affected with the same threaded
pins or screws.
Taper locks are cylindrical on the inside, tapered
on the outside, and slit longitudinally. The
smaller bushes 2 and 3 have in the large face
their cylindrical blind holes in parallel to the axis,
which, however, are only placed halfway in the
bush material. The other halves of these blind
holes are threaded and are placed inside the hub.
Threaded pins or screws (F) are screwed to the stop in the boreholes using an Allan key. When
the screws are tightened further using a certain amount of force the hub is drawn up to the tapered
bush (B) which is pressed onto the shaft with great force.
