WARNING

Before lubricating, repairing or inspecting, disengage all controls and stop engine. Wait until all moving parts have come to a complete stop. Remove the safety key to prevent unintended firing of the engine.

IMPORTANT

Refer to the Final Adjustment section of the Set-Up instructions after replacing drive and auger belts.

8.Place a block of wood underneath the auger housing as shown in Figure 6-9 and separate auger housing from the frame by tilting the housing forward and pulling up the handles.

9.Block the impeller with a piece of wood to prevent if from spinning and use a 1/2” wrench to remove the hex screw and washer from the center of the pulley on the auger housing. See Figure 6-10.

10.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 6-10.

NOTE: The pulley adapter may slide off the auger input shaft when removing the pulley. Use extra caution to ensure the adapter does fall and/or get damaged when removing the pulley.

11.Place the new auger belt in the V-groove of the auger pulley and place the pulley w/belt inside the belt keepers.

12.Turn the pulley as necessary to align its three slots approximately with the posts of the pulley adapter, then move the brake bracket assembly away from the input shaft. While aligning the pulley slots and adapter posts, push the auger pulley fully onto the adapter. Refer to Figure 6-10.

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 6-10.

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

14.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.

If also replacing the drive belt, proceed to the “Drive Belt” instruction. If not, reassemble by performing the previous steps in the opposite order and manner of removal.

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

Proper 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.

1.To adjust, disconnect ferrule from brake bracket assembly and thread ferrule in (towards idler) to increase tension on belt, and out to decrease tension. See Figure 6-6.

NOTE: The brake puck must always be firmly seated in the pulley groove when auger control is disengaged.

IMPORTANT: Repeat the “Auger Drive Control Test” from the Assembly section before operating snow thrower.
