Thrust is handled by the 55 mm #3 bearing  at the propeller end of the crank. Fully utilizing its robust #4  main bearing, the Revmaster crank has built in oil-controlled propeller capability, a feature unique in this horsepower  range; non-wood props are usable with these engines. Takeoff power is rated at 85 at 3350 rpm. The additional  power comes from a bore of 94mm plus lengthening of the  R-2200’s connecting rods, plus increasing the stroke from 78  to 84 mm. The longer stroke results in more displacement,  and longer connecting rods yield better vibration and power  characteristics. The lower cruise rpm allows the use of longer  propellers, and the higher peak horsepower can be felt in  shorter takeoffs and steeper climbs. The Revmaster’s four main bearing crankshaft runs on a 60  mm center main bearing, is forged from 4340 steel, and uses  Moving from the crankcase and main bearings, the cylinders  are made by using centrifugally cast chilled iron. The pistons  are forged out of high quality aluminum alloy, machined and  balanced in a set of four. There are two sizes of pistons, 92mm  and 94mm, designed to be compatible with a 78mm to 82mm  11-14
