ENGINE 612.981 without CODE ZU7 (National version for Canada) without CODE ZU8 (National version for USA) without CODE ZU9 (National version for Mexico)
ENGINE 611.960/961/962/980/981/983/987, 612.961/962/963/965/966/967/990, 613.960/961
The crankshaft bearing caps are machined together with the crankcase, and they must not be interchanged,
as otherwise, the unobstructed movement of the screwed connection is not ensured.
The crankshaft bearing caps are fitted into the side of the crankcase. The fit is off-centered 0.5 mm with the result that the bearing caps can be installed only in one position. If installed correctly, the lug (arrow) on the crankshaft bearing cap points to the left, when viewed in direction of travel (inlet side).
The crankshaft bearing caps (2, 2a) are numbered consecutively starting with the first crankshaft bearing cap at the front.
