Figure 7-6

6.Block the impeller with a piece of wood the prevent from spinning and use a 1/2” wrench to remove the hex screw and flat washer from the center of the auger input shaft and auger pulley adapter. Refer to Figure 7-7.

7.Lift the brake bracket assembly out of the pulley groove and slide the pulley assembly off the posts of the auger pulley adapter to remove the old belt. Refer to Figure 7-7.

NOTE: The pulley adapter may slide off the auger input shaft when removing the pulley. Use extra caution to

NOTE: If the pulley adapter was removed with the pulley, align the splines of the pulley adapter and auger input shaft, and push the pulley and adapter onto the input shaft. Refer to Figure 7-7.

10.Slide the washer onto the hex screw removed earlier and apply Loctite 262 to the threads of the hex screw.

11.Insert the hex screw through the pulley assembly and into the threads of the input shaft. Torque the hex screw to 250-325 in. /lbs. to secure the auger pulley assembly on the input shaft.

12.If also replacing the drive belt, proceed to the “Drive Belt” instruction. If not, reposition the transmission frame back onto the auger housing. Install the drive belt on the engine pulley, re-connect the auger cable “Z” fitting and auger idler rod ferrule to the brake bracket. Reposition and secure the engine pulley belt guard, and re-install the belt cover.

NOTE: Make sure to remove the piece of wood blocking the impeller.

Check the auger drive belt adjustment. With the auger clutch lever in the disengaged position, the top surface of the new belt should be even with the outside diameter of the pulley.
