Stop Bolt Friction Wheel Removal (Models 2410, 2620 & 2840) If the snow thrower fails to drive with the drive control engaged, and performing the drive control cable adjustment fails to correct the problem, the friction wheel may need to be replaced. Follow the instructions below. Examine the friction wheel for signs of wear or cracking and replace if necessary: 1. Allow the engine to run until it is out of fuel. Do not attempt to pour fuel from the engine. 2. Place the shift lever in third Forward (F3) position. 3. Carefully pivot the snow thrower up and forward so that it rests on the auger housing. 4. Remove the frame cover from the underside of the snow thrower by removing the self-tapping screws which secure it. Remove the right-hand wheel by removing the screw and bell washer which secure it to the axle. See Fig. 7-8. Figure 7-7 7. Slip the drive belt off the pulley and between friction wheel and friction wheel disc. See Fig. 7-7. 8. Remove and replace belt in the reverse order. Be sure to re-install the stop bolt. NOTE: Engaging the drive control will ease reinstallation of the belt. Friction Wheel Inspection (Model 3090XP) If the snow thrower fails to drive with the drive control engaged, and performing the drive control cable adjustment fails to correct the problem, the friction wheel may need to be replaced. NOTE: Special tools are required and several components must be removed in order to replace the snow thrower's friction wheel rubber. See an authorized Service Dealer to have the friction wheel rubber replaced or phone Customer Support as instructed on page 2 for information on ordering a Service Manual. To inspect the friction wheel, proceed as follows: 1. Allow the engine to run until it is out of fuel. Do not attempt to pour fuel from the engine. 2. Carefully pivot the snow thrower up and forward so that it rests on the auger housing. 3. Remove the frame cover from the underside of the snow thrower by removing four self-tapping screws which secure it. See Fig. 7-8. 4. Examine the friction wheel for signs of wear or cracking.
