Introduction. This manual is divided into sections. This first section contains information which generally pertains to all crankshafts. The crankshaft dimensions shown in the various sections are intended for service identificaion purposes only and may vary somewhat due to manufacturing tolerances. The drawings are not to scale.

The crankshaft is a major piece of your performance puzzle. It converts reciprocating motion to rotary motion, absorbs the shock of combustion, accelerates and decelerates the reciprocating components, delivers the oil to the connecting rod bearings, resists twist and deflection, mounts the drives for the cam, transmission, damper and front-of ...
The cranking motor mounting must always be tight and the drive must be in good condition. The condition of the drive can be established by operating the cranking motor two or three times and noting the action of the drive. The cranking motor must be removed if the drive is to be actually seen and exam-ined. On overrunning clutch type crank-
Draw a Free Body Diagram of the Crankshaft with various horizontal and vertical forces. Calculate the piston force. (We know Maximum Piston pressure, It can be assumed according to the industry norms as 200 bar for Diesel & 180 bar for SI Engines).
Rotate the crankshaft clockwise (as viewed from the front) to place the number one cylinder piston at top-dead-center on the exhaust stroke by aligning the dimple (4) on the crankshaft with the block/bearing cap junction (5).
8.1.1 Function and Requirements of Crankshaft Assemblies Together with both the piston pins and the crankshaft’s crank pins, the connecting rod in reciprocating piston engines converts oscillating piston motion into rotary crankshaft motion. Running smoothness is a universally important criterion for the design of crankshaft assemblies.
