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. Reposition scraper blade and tighten

lock nuts.

3. Adjust skid shoes.

IMPORTANT: ALWAYS adjust skid shoes

after adjusting scraper blade to prevent

premature wear to scraper blade or damage

to housing.

SKID SHOES

(Figure 19)

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" (3 mm) between

scraper blade and hard smooth

surfaces. Allow 7/8" (22 mm) between

scraper blade and uneven or gravel

surfaces. Retighten hardware.

NOTE: Keep housing level by adjusting skid

shoes equally.

SHEAR BOLTS

(Figure 20)

IMPORTANT: Use only Ariens OEM shear

bolts for replacement. Use of any other type

of shear bolt may result in severe damage to

unit. See SERVICE PARTS on page 31.

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 case.

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).
