Shearbolt Protection
The Snow Blower is protected from large objects
entering the Snow Blower housing with a drive shaft
shearbolt and a driveline shearbolt. They must be kept
tight to keep them from wearing on the bolt holes and to
prevent bolt wear.
Drive Shaft Shearbolt
Refer to Figure 6-2:
There are two holes above the roller chain for storing
extra drive shaft shearbolts with lock nuts. A good
practice would be to keep several shearbolts on hand at
all times. Shearbolts canbe purchased fromyour nearest
Land Pride dealer.
1. Loosen hand knobs (#6) and remove rear drive shaft
guard (#3).
2. Realign holes in drive shaft tabs (#1 & #2) and insert
new shearbolt (#4) through the holes. Secure bolt
with hex nylock nut (#5). Tighten nylock nut.
3. Retighten bearing set screws (#7).
4. Replace guard (#3) and secure with knobs (#6).
Driveline Shearbolt
Refer to Figure 6-3:
There are two holes near the gearbox for storing extra
driveline shearbolts with lock nuts. Agood practice would
be to keep several shearbolts on hand at all times.
Shearbolts can be purchased from your nearest Land
Pride dealer.
Refer to Figure 6-4:
1. If included, unsnap and open side doors on gearbox
shielding to access shearbolt end of driveline.
2. Realign holes in end of driveline tabs (#1 & #2) and
insert new shearbolt (#3) through holes. Secure bolt
with lock nut (#4). Tighten lock nut.
3. If opened, close side doors on gearbox shielding.
IMPORTANT: Always retighten set screws (#7) in
outer bearing after replacing a broken shear bolt to
ensure the set screws have not come loose.
