Maintenance
AlphaBlower Assembly
1. Apply grease to all spline pins before
installation to prevent the pins from corroding.
2. Return the impeller axle with the impeller and
install the flanged bearing, pressure ring and
locking ring.
3. Position the gearbox upside down on a jack or
similar (make sure it is well supported).
4. Push the gearbox onto the spline pin on the
claw coupling.
5. Turn the gearbox 180 degrees and install the
fixing screws and the friction washers.
NOTE: The friction washers must be placed
under the fixing screws with the
curved side facing upward.
6. The torque must be 147-184 ft lbs for the fixing
screws for the gearbox.
7. Then lock the screws using locking washers.
8. Ensure that there is no sloping angle between
the gearbox axle and the impeller axle and
between the auger and the spigot on the
gearbox.
NOTE: Any variations will result in heavy wear
to the claw coupling on the impeller
axle and the couplings on the augers.
Auger Axle Installation
When the augers are turned by 1/2 a turn there
should be no more than 0.04” variation measured
between the flanges. If the variation is greater
than this, shims must be placed between the
gearbox and the fixing plate for the gearbox. The
bolts on the coupling for the augers must NOT be
fully tightened! This could damage the coupling
and the gearbox.
NOTE: When the augers are pulled in on the
spline pin on the gearbox these must
be positioned at 90 degrees in relation
to each other. This is to ensure that
snow is fed into the impeller evenly.
Incorrect installation can cause serious damage to
the blower, especially to the augers and gearbox.
Cup springs will absorb movements between the
auger axle and the axle on the gearbox. It is
IMPORTANT that the innermost nut is not fully
tightened so that the cup springs are fully
compressed. If this happens, the cut out clutch
and gearbox may be damaged.
Figure 10
Tighten the inner most nut (Item 1) until the cup
springs (Item 2)
[Figure 10] are situated next to
each other in pairs as shown in the figure. When
the outermost nut is tightened, the screw should
protrude 0.04 to 0.118” outside of the nut.
