The roller bearing is precluded against longitudinal displacement by the crankcase holder
internal collar at the front and by a spring ring lodged in the crankcase holder recess at the rear.
In addition to the central hole, the vertical wall has four more holes: three holes for
breathing and one hole for fixing the cam plate when timing the engine.
Two holes for draining oil to the oil sump, leading to the bored seat for the oil baffle are
made in the lower flange of the intermediate crankcase front portion.
Nine inter-flange bridges are made at the intermediate cranlccase front portion (Ref. Pig.
3). The bridges have holes for coupling bolts. Nine semi-flanges with four cylinder attachment
studs each are also arranged there.
The vertical wall of the intermediate crankcase rear portion (Ref. Fig. 4) has a central hole
for pressing in the bronze holder of the rear roller bearing of the crankshaft and three breathing
holes. The holder and the bearing are locked likewise in the front portion of the intermediate
crankcase.
Two holes are made in a rectangular projection of the rear flange lower part. One hole is
used to drain oil from the rear cover to the crankcase and leads to the bored seat for the oil baffle,
the other (with oil transfer bushing), for scavenging oil from the oil sump to the oil tank. The oil
sump attachment flange has a hole for draining oil from the crankcase and another hole for
scavenging oil from the oil sump.
The intermediate crankcase rear portion likewise the front portion has nine inter-flange
bridges and nine semi-flangea with four cylinder attachment studs each.
2.3. CRANKSHAFT
The split-type single-throw crankshaft of the engine (Ref. Pig. 5) comprises front and rear
sections interconnected by a coupling bolt. The front and rear sections of the crankshaft are made
of heat-treated high-grade steel. Front section (11) includes a front end, web, main journal and
crank pin making up one integral part.
The front part of the crankshaft hollow end has pressed-in steel bushing (8) potted with
lead bronze. The bushing is a rear support for the airscrew shaft. The rear of the end space is
closed with aluminium alloy plug (30). The plug is locked with retainer (32).
The end front has splines for mounting the gearbox drive gear hub; the crankshaft front
main journal is located closer to the web. A groove for key (10) of the timing drive gear is made
between them on the shaft outer surface.
Arranged on the crankshaft front end after the web are roller bearing (7), adjustment ring
(6), spacer (5) of the cam plate, timing drive gear (4), adjustment ring (3), thrust bearing and
gearbox drive gear ring hub. The stack is tightened on the shaft by nut (2). The nut is locked with
cotter pin (1).
