MAINTENANCE

Nuts And Bolts

1.Check all nuts and bolts for tightness after the first 5 hours of operation then yearly.
IMPORTANT: Shear bolts should not be over tightened, as this may cause unpredictable shearing action.

Drive Chain

1. Retighten the auger drive chain when slack exceeds 3/4 inch at the center of the bottom chain section.
2. The drive chain is tightened by loosening the bolts on the idler roller plate and forcing the idler against the chain,
then retightening the bolts.
3. DO NOT OVER TIGHTEN as this will increase wear of the idler roller. Allow approximately 3/8 inch of slack up
or down at the center of the bottom chain section.
Shear Bolts
1. IMPORTANT: If a shear bolt breaks during operation immediately shut down the tractor and replace the

shear bolt.

2. The shear bolts used on these Alamo Industrial snowblower fans are part number 00783578. This shear bolt
is machined around the shank to facilitate shear at the protected fan load.
3. Specified shear bolts and their locations are listed below:
NOTE: Special machined bolt required for fan shear.
IMPORTANT: Tighten nut only enough to draw the shear plates together. Do not over tighten nut.
Occasionally apply grease to the shear plates.
IMPORTANT: Replacement of the shear bolt with one of any other grade or size will be considered
an unauthorized modification and the warranty will be void.
