SCRAPER BLADE
IMPORTANT: Damage to 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 22)
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 shoe to flat surface.
Allow 1/8 in. (3 mm) between scraper
blade and hard smooth surfaces. Allow
7/8 in. (22 mm) between scraper blade
and uneven or gravel surfaces.
Retighten hardware.
NOTE: Keep housing level by adjusting skid
shoes equally.
SHEAR BOLTS
(Figure 23)
IMPORTANT: Use only Ariens OEM shear
bolts for replacement. Use of any other type
of shear bolt may result in severe damage to
unit and may void the warranty.
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 and its components.
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).
