After jacking up front axle and removing the hub cap, withdraw cotter key holding nut "A." Turn nut "A" to the right until a slight drag is felt when turning the wheel slightly by hand. Then loosen the nut just sufficiently to permit the wheel to turn freely. Insert cotter key.
Rear Wheel Bearings
To adjust rear wheel bearings, jack up rear axle and remove both rear wheels. Remove the four nuts from bearing cap "A" and remove cap. By removing shims "B" under the cap the end play of the axle shaft is decreased. Total play between axle shafts should be from .005" to .010" (.12 to .25 mm.) which is perceptible by pulling shaft in and out with the hand. It is necessary that the thickness of shims at each rear wheel be approximately the same, so when adjusting remove a thin shim from each side and repeat, if necessary, until only a slight amount of play is evident. Be sure the axle shafts turn freely before building up.
Removing and Installing Wheels
To remove a wheel, place a screwdriver between the hub cap and hub and pry off cap. Loosen the four cap screws "B" (illustration [top of page]) with the socket wrench provided. Remove one cap screw in the lowest position and insert the handle of the wrench through the screw hole into the hub. While holding the wheel in position with the wrench, remove the other cap screws and lift off the wheel. The wheels should be jacked up just sufficiently to clear the ground. When replacing the wheel, place the handle of the wrench through the lower cap screw hole, lift up on the wrench so that the wheel will clear the ground and push in place. Align by moving wrench back and forth. Then start two of the cap screws, remove the wrench and start the remaining two. Tighten every other cap screw until all are down enough to hold wheel in place, making sure it is square on the hub. Continue tightening every other screw until all are secure.
