Interference fit of crankshaft bearing cap - AH03.20-P-4351-02A
Engine 111, 601, 602, 604, 605, 606
The crankshaft bearing caps are machined together with the crankcase and must not be interchanged.
The crankshaft bearing caps are interference-fitted in the side of the crankcase. The fit is off-centered 0.5 mm with the result that it is only possible to install the bearing caps in one position. If the bearing caps are correctly installed, the lug (arrow) on the crankshaft bearing cap is facing toward the left (intake side), when viewed in the direction of travel.

The crankshaft bearing caps (2, 2a) are consecutively numbered, beginning with the first crankshaft bearing cap at the front.
