The shaft must, however, always run with the com-pression part of the stroke on the upper half revolution, , clock-wise when viewed from the gear end. The crankshaft I4 is made ofheavy forged steel and, besides having ample end bearings 13 andi^ of bronze, is provided with a large babbitt-lined center bearingwhich is a part of the crankcase cylinder casting 17. Lubrication, The parts mentioned above are all lubricatedfrom a bath of oil, poured into the dust-proof crankcase through aspecial fitting 18, which acts as a gage of the oil level; the fitting is A|R0I8CHARG£.
