The transmission lubricant should be maintained to the level of the filler plug "A." In warm climate or during summer months use transmission gear oil S.A.E. 110. In winter or when near-zero temperatures prevail use transmission gear oil S.A.E. 80. Remove drain plug "B" every 5000 miles, flush out with 1 pint of kerosene and refill with oil of proper type.
Rear Axle
The oil supply should be kept level with the lower edge of the filler plug opening "A." Use a good grade of heavy-bodied gear oil. S.A.E. 110 in warm climate (summer temperatures)—S.A.E. 90 when lower temperatures prevail (winter). During the winter months be sure the oil you are using will flow at the temperatures encountered.
Wheel Bearings
The front wheel bearings should be lubricated every 5000 miles with a good grade of cup grease. Remove hub and wash bearings and inside of hub with kerosene. Pack each bearing and hub with 3 ounces of No. 2 cup grease (see page 12 for adjusting wheel bearings).
The rear wheel bearings should be lubricated every 5000 miles with No. 3 cup grease. Remove four nuts from bearing cap "A" and remove caps and shims. Pull bearing and after washing bearing and housing in kerosene repack each bearing housing with 1-1/2 ounces of cup grease. Then replace bearings, shims and caps, draw up wheel hub tight on shaft and install cotter pin.
