4.5.1 Compressor house adjustment
Rotrex can deliver superchargers with 6 different air outlet positions following your order
specifications. It is possible to change the pre-set outlet direction carefully applying the
following procedure:
A.
First identify the desired outlet direction of the compressor housing respecting the
±15
to horizontal specified in Section 4.4.2
B.
Loosen the two large counter-bore bolts securing the
compressor housing to the gear housing. Do this
carefully and only a couple of turns on each screw at
a time – making sure the compressor housing does
not come off at an angle damaging the impeller
C.
With the bolts completely removed, the compressor
housing can be rotated by hand while still on the gear
housing. Again, pay attention not to damage the
impeller during this operation
D.
With the compressor outlet at the desired location fit the two bolts and tighten to
the torque stated in the respective datasheet. Tightening of the two large counter-
bore bolts must be done incrementally, turning each bolt a couple of turns – making
sure the compressor housing is not mounted at an angle; damaging the impeller
Not following this procedure may result in impeller imbalance and ultimately cause
permanent damage of supercharger system and/or other systems in the vehicle.
The supercharger should be delivered to the end user or installer with a pre-set outlet
direction. To support this, every Rotrex unit includes a warning label as shown below.
In case of any question or doubt don’t hesitate to contact your Rotrex supplier.
