Overview - Belt Pulley, SANDEN A/C Compressor
- Nut
- 25 Nm
- To protect the A/C compressor input shaft threads, they may be covered with a plastic cap (the plastic cap is not illustrated).
-- Hold the belt pulley securely with a commercially available oil filter band wrench to loosen and tighten the hex nut.
-- The threads of the nut that was installed with locking fluid must be cleaned (for example, using a thread tap). Otherwise, there is a risk that the input shaft will break off during assembly.
-- Clean the threads of the A/C compressor input shaft with a wire brush.
-- Insert the nut with locking compound. Locking fluid. Refer to the Parts Information.
- Bolt
- 12 Nm
-- Hold the belt pulley securely with a commercially available oil filter band wrench to loosen and tighten the bolts.
-- The threaded holes into which the self-locking bolts or bolts with locking fluid are installed must be cleaned (for example with a thread tap). Otherwise there is the risk that the bolts could break off when they are removed again.
-- Clean the threads of the bolts that were installed with locking fluid using a wire brush. Then insert the bolts with locking fluid. Locking fluid. Refer to the Parts Information.
- 12 Nm
- Drive Plate
- With overload protection (securing spring elements); is activated when the torque is too great (for example, if the A/C compressor runs with resistance) and the belt pulley runs freely without driving the A/C compressor.
- The drive plate spring elements dampen vibrations and noise
- Circlip
- Always replace
- Install on the proper side, beveled insertion edge -A- faces away from the A/C compressor; flat side faces the A/C compressor
- Belt Pulley
- With rubber elements -B- and threaded plates -C- for decoupling the belt pulley from A/C compressor input shaft, dampens vibrations and noises
- Depending on the version, the threaded plates can also be connected to each other by a ring.
- A/C Compressor
- Clean the A/C compressor input shaft before installing the belt pulley
