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 can be purchased from your
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. A good 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.
