4.4 MOUNTING OF THE ALTERNATOR
4.4.1 General
Consult your engine supplier for the availability of a
mounting bracket and other necessary mounting
hardware to mount the alternator on the engine.
Mastervolt Alpha alternators require two A-type V-
belts of equal length (measured pair) for
transmission.
As every engine differs from the other, Mastervolt
can not give any specific mounting instructions for
any particular engine.
4.4.2 Rotating direction
Except for the model 24/95 Compact, the Alpha
alternator is equipped with a bidirectional fan.
Therefore it may rotate in either a clockwise or
counter clockwise direction.
The 24/95 Compact must be mounted in such way
that it rotates clockwise, when looking to the side of
the fan (see figure 4)

only (all other models are bidirectional)
4.4.3 Mounting step-by-step
1 Determine the alternator mounting location.
2 Loosely attach the mounting bracket to the
engine with the mounting engine bolts. Position
the alternator mounting foot between the two
ears (figure 5, references A and B) on the
mounting bracket with the alternator mounting
bolts. Note that the ear at the rear side of the
alternator housing should be fixed in such way
that it can freely move in the direction of the
arrow (see figure 5, reference A). This is to avoid
mechanical stress due to possible high
temperatures of the alternator.

3 Align the alternator pulley with the engine drive
pulley as shown in figure 6 and tighten the
bracket mounting bolts, securing the mounting
bracket to the engine.
