3 January 2017
Engine Description
An enlargement of each casting’s lower parting flange at the front end forms half of a boss
which is machined and studded to make a mount pad for a vacuum pump. A semicircular
flange at the rear of the crankcase bottom surface is machined flat and studded to form the
front half of the oil sump mount pad.
Two studs driven into bosses at the lower parting flanges are used to attach the intake
manifold. The crankcase breather elbow is screwed into a tapped boss forward of No. 3
cylinder. An upper and a lower arm at the rear of each case casting affords an engine
mounting point. The arm bosses of the crankcases are bored through and counterbored for
mount bushing assemblies. The flange surrounding the rear end of the crankcase is
machined flat and studded to attach the accessory case. The studded fuel pump mount pad
on the 1-3 side of the crankcase is a legacy feature which is no longer used. The pad is
supplied with a cover.
