Abstract
A method of assembling a crankshaft and a crank member comprises supplying a crankshaft including a crankpin which extends between crank arms, supplying two halves of a crank member, which are fixed to each other about the crankpin such that in assembled condition the crank member is rotatable about the crankpin and comprises a bearing portion having an outer circumferential wall for bearing a big end of a connecting rod and an external crank member gear for driving the crank member about the crankpin, wherein the halves are fitted about the crankpin, hence creating two contact faces at opposite sides of the crankpin, after which both halves are fixed to each other in circumferential direction by means of applying at least a fixation at a fixing place located remote from the bearing portion and the toothed surface of the crank member gear.
