4.8 Manufacture / procurement of compressor mounting bracket
Fig. 402 shows the dimensions and attachment points for a TM16 HD compressor with horizontal connection. The
connecting dimensions (83.3 and 112) are the same for all compressors (see 2.4).
The compressor must be installed in accordance with the vehicle manufacturer's instructions.
The following points must also be observed when manufacturing / procuring the mounting bracket:
– Check whether compressor mounting brackets can be obtained from the vehicle manufacturer. The vehicle chassis
and engine identification numbers specified in the vehicle's registration documents will be required for this purpose.
– Check the availability of the universal compressor mounting bracket from Webasto (Fig. 403) and whether it can be
used.
– Permitted installation position of the compressor.
– Choose a V-belt pulley diameter that does not exceed the upper or lower compressor operating speed limits.
– Ensure that V-belt pulleys on the engine and compressor are aligned.
– Sufficient V-belt wrap angle (> 120°).
– The compressor must be securely mounted to at least 4 flange holes with a facility to adjust the tension of the V-belt.
– The position of the refrigerant connections and the V-belt pulley dimensions depend on the compressor used.
