SHEAR BOLTS (Figure 22) 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 33. 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. 2 5. Secure handlebar to frame with hardware removed in step 4 using the different hardware locations shown in Figure 23. 1 2 1 2 3 3 1 1. Auger 2. Shear Bolts Figure 22 OS7150 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). HANDLEBAR HEIGHT (Figure 23 and 24) CAUTION: AVOID INJURY.
