6.3 UNIT UPGRADES

Discharge Deflector Control Force (5HP)
938002, 938004, 938302
The discharge deflector control force is dependent on
the bolt through the compression spring in the deflector
handle assembly and by the construction of the
housing assembly. To correct breakage of the housing
alignment pins that go into the handlebar tube, remove
them and replace with a flat head screw. The flat head
screw will hold the deflector housing securely to the
handlebar. The compression spring will then only be
required to control the chute deflector lever force.
Blower Housing Filling With Snow
Snow may enter the engine compartment and get
trapped inside with no exiting points. To control the
amount of snow that would be trapped inside the
engine compartment, two 3" holes will need to be
added to the chassis bottom and allow the snow to exit.
To control the snow from entering the drive belt area,
use 538012 3 HP Update Kit (938001 - S/N 000101 -
006245, 938003 - S/N 000101 - 002350, 938301 - S/N
000101 -000251) 53801300 5HP Update Kit (938002 -
S/N 000101 -00 6280, 938004 - S/N 000101 - 003900,
938302 - S/N 000101 - 000241). New holes will need to
be drilled for the two additional screws, in the front of
the blower housing where the right and left bearing
support plates come into contact with the impeller
housing.
