Other Maintenance Items
Shear bolt Replacement
The auger and discharge fan both have special shear bolts that are designed to break if either the auger
or fan are put under an excessive load. In the event a shear bolt does break, replace it with the bolt
specified here:
Fan, 5 x 40 mm with 1/2" shoulder, SAE Grade 8, Auger, 5 x 45 mm with 1/2" shoulder, SAE Grade 8.
See Blower Head in the parts listing for the locations of the shear bolts.
Belt Replacement
While it is not necessary, removing the snowblower from the lawn tractor makes this job much easier.
See page 30 for the snowblower removal procedure.

If the snowblower remains on the lawn tractor, remove the silver, 10 mm flange bolt on the right side
