1 Place motorcycle on a stand so that the front wheel is off the ground. 2 Using a 27mm socket remove the front axle nut. Using a 10mm socket, loosen the four front axle pinch bolts. Slide front axle out of forks and remove front wheel. 3 Insert a long punch (with a good square edge) into the center of the aluminum wheel bearing spacers and push up against the inner edge of the spacer on the opposite side of the wheel (Fig. 1). Using a hammer, tap the punch around the entire circumference of the spacer until it completely slides out of the bearing (Fig. 2). Turn the wheel over and remove the other spacer in the same way. 4 Use a long screwdriver or narrow pry bar and pry the seals out of each side of the wheel (Fig. 3). 5 Using snap ring pliers, remove the bearing retaining snap ring from the brake rotor side of the wheel. (Fig. 4) NOTE: 2003 – CURRENT MODELS USING # 16-092 KIT DO NOT USE THIS SNAP RING. 6 Insert a long punch (with a good square edge) into the center of the wheel bearing, and push up against the inner edge of the bearing on the opposite side of the wheel. Using a hammer, tap the punch around the entire circumference of the bearing until it completely slides out of the hub. Turn the wheel over and remove the other bearing in the same way. NOTE: It may be necessary to tap on the punch sideways at first to knock the center aluminum sleeve off center so that you are able to get the punch on the edge of the bearing. 7 Clean areas where bearings will be inserted back into hub and apply a thin coat of grease around the machined hub surface. Tap the bearing on the snap ring (if used, either side if not) side of the hub into the machined hub surface, making sure to keep it square with the hub as it goes in and only tap on the outer race of the bearing. Once you get the bearing flush with the outer edge of the hub, use a socket or piece of pipe that is just smaller than the outside diameter of the bearing to finish tapping the bearing into the hub. (Fig. 5) 8 Install the bearing retainer snap ring (if used) into the groove machined in the hub, and then tap the seal in place over the snap ring with the spring on the seal in towards the center of the wheel. Tap in the aluminum spacer in the center of the seal.
