Blueprint LeC. 2519. shews the above arranged for splash lubrication with a small vertical web arranged to receive some of the splash direct from the crank. We cannot see why these bearings should not be made in piston aluminium alloy. These present Phantom bearings are in bronze, and bound to be very heavy and difficult to machine by comparison. Failing aluminium, cast iron makes a very good camshaft bearing. E.{Mr Elliott - Chief Engineer} | ||
