SERVICE AND ADJUSTMENTS

WARNING: AVOID INJURY. Read and understand the entire Safety section before proceeding.

SCRAPER BLADE

IMPORTANT: Damage to auger/impeller housing will result if blade wears down too far.

Scraper blade is adjustable to compensate for wear.

To adjust scraper blade:

1.Tip unit back onto handlebar, support housing and loosen nuts retaining blade.

2.Adjust skid shoes to fully raised position (housing closest to ground).

3.Reposition scraper blade flush with skid shoes and tighten lock nuts.

SKID SHOES

(Figure 26)

Skid Shoes should be adjusted as conditions require.

1.Position unit on a hard, flat, smooth level surface.

2.Adjust skid shoes by inserting a spacer of desired thickness under center of scraper blade, loosen skid shoe hardware, slide skid shoes to flat surface. Allow 1/8 in. (3 mm) between scraper blade and hard smooth surfaces. Allow 1-1/4 in. (30 mm) between scraper blade and uneven or gravel surfaces. Retighten hardware.

NOTE: Keep housing level by adjusting skid shoes equally.

SHEAR BOLTS

(Figure 27)

IMPORTANT: Use only Ariens shear bolts for replacement. Use of any other type of shear bolt may result in severe damage to unit. See SERVICE PARTS on page 36.

Occasionally a foreign object may enter the auger/impeller housing and jam the auger, breaking shear bolts which secure the auger to the shaft. This allows auger to turn freely on the shaft which may help prevent damage to gear drive.

For Replacement:

1.Align shear bolt holes in auger with shear bolt holes in the shaft.

2.Drive shear bolt through hole (if shear bolt was broken this will drive remaining part from shaft).

3.Secure shear bolt with nut.

NOTE: DO NOT overtighten the shear bolt. Tighten shear bolt to 5.8 – 12.2 lbf-ft (7.9 – 16.5 N•m).
