design of the intake ducts and the pushrod arrangement. Contrary to the old design, which had the two intake ducts conjoined into a single one, the new design had separate intake ducts for each cylinder. This also necessitated a slight change in the valvetrain, with the two pushrods now placed separately to both sides of the intake duct, instead of both pushrods being placed at one side of the combined intake duct in the older design. Also the number of mounting bolts for the cylinders has been increased, with each cylinder pair now being held to the crankcase by ten bolts.

The upper layshaft provided the tachometer output and also was used to drive the two magnetos, which were mounted transversely and driven via separate bevel gears.

Lubrication was forced, with a piston pump located mid engine at the bottom of the crankcase, collecting and recirculating the oil from the crankcase. Small amounts of fresh oil were augmented by the piston pump automatically. The oil was fed to the main journals of the crankshaft, from where it was

The crankcase was made of aluminum and cast in separate upper and lower half parts, with the upper half having mounting arms cast into it. The crankshaft was supported by two intermediate and two outer plain bearings, with additional thrust ball bearings at the propeller end. The propeller had an

The cylinders were machined from steel separately, with intake and exhaust ducts as well as cooling jackets welded in place in a separate step. While the steel cylinders were still combined to pairs, sharing the same cooling jacket, the change to steel cylinders was accompanied by a change in the

The camshaft was driven from the crankshaft via an intermediate spur gear on the control end, and two additional vertical layshafts, both driven from the crankshaft via bevel gears, were used to drive the magnetos and the water- as well as the oil pump. The centrifugal water pump, located on the

six-cylinder engines. Alongside many other changes, the major improvements were the introduction of newly designed steel cylinders and the completely redesigned crankcase, which now had an integrated oil pump and a completely modernized lubrication system.

Cast iron cylinders like in the previous engine design were also available, although in updated form to match the redesigned engine parts (i.e. separate intake ducts, new pushrod arrangement and increased number of crankcase mounting bolts).
