Inspection & Replacement of the
Impeller / Collector Belts
The impeller / collector belts are also located under the belt
guard between the engine and impeller. Follow the
procedure below to inspect or replace the belts. Always
replace these belts as a set. Remove key, remove spark plug
cable from spark plug and ground to the engine.
1. Loosen the two fasteners on either side of the belt cover.
The cover will lift up and away from the snow blower
during removal.
The fasteners require a 10mm wrench or socket/ratchet.
2. Remove the impeller belts from the front of the engine
pulley.
- Pull the front belt toward the front of the snow blower
starting at the bottom of the engine pulley on the side
without the idle pulley.
- The belt may be snug, and it may be necessary to
rotate the crankshaft or use a screwdriver to assist with
rolling the belt out of the pulley groove.
- Pull the back belt to the first pulley groove, then off of
the front of the engine pulley.
3. Put snow blower into the vertical service position
standing on the front of the collector housing as
instructed in the service position page of the manual.
4. Remove the bottom cover (6 bolts) with a 10mm wrench
or socket/ratchet. See diagram in Inspection and
Replacement of Transmission Drive Belt.
5. Using a piece of rope or strap, tie the impeller / collector
engagement handle into the engaged position. This will
pull the brake off of the large impeller pulley allowing the
belts to be removed from this pulley.
6. Remove the belts one by one toward the top of the snow
blower. Tie the transmission engagement handle in the
engaged position if necessary for additional clearance
while removing the belts.
7. Reroute the new belt in reverse order from the removal
process, and reverse the order of these steps to properly
reassemble the belt to the pulleys.
Double check that the belt is fully seated in both pulleys
before replacing covers.
Service Adjustments
IMPORTANT! The snow blower belts are adjusted to
ensure the augers stop turning within 5 seconds of
releasing the augers/impeller control lever. If you are
making any belt adjustments whatsoever, for your safety
and the safety of others around you, you must ensure the
belts are re-adjusted to achieve this design specification.
