A method of assembling a crankshaft (1) and a crank member (3, 4) comprises the steps of supplying a crankshaft (1) including a crankpin (5) which extends between crank arms (6), wherein the crankshaft (1) has a crankshaft axis (2) and the crankpin (5) has a crankpin axis (7), supplying two halves of a crank member (3, 4), which are fixed to each other about the crankpin (5) such that in assembled condition the crank member (3, 4) is rotatable about the crankpin (5) and comprises a bearing portion (12, 17) having an outer circumferential wall for bearing a big end of a connecting rod and an external crank member gear (8, 9, 14, 15) for driving the crank member (3, 4) about the crankpin (5), wherein the halves are fitted to each other about the crankpin (5), hence creating two contact faces (18, 19) at opposite sides of the crankpin (5) extending between opposite axial outer sides of the crank member (3, 4), after which both halves are fixed to each other in circumferential direction by means of applying at least a fixation (20) at a fixing place (22) located remote from the bearing portion (12, 17) and the toothed surface of the crank member gear (8, 9, 14, 15). |
