Installing the crankshaft into the engine block
1 – oil pump; 2 – pump mounting bolt (M = 25 Nm); 3 – pump drive sprocket on the crankshaft; 4 – liner – upper and lower parts of bearing 1, 2, 4, 5; 5 – crankshaft bearing cap bolts; 6 – bearing caps; 7 – third bearing shell – upper and lower parts; 8 – flywheel gear; 9 – bolt (first tighten to 10 Nm, then turn 90); 10 – liners for setting the axial clearance of the crankshaft; 11 – crankshaft
The engine block is made of grey cast iron with moulded cylinders. The crankshaft bearing caps are also made of cast iron and are an integral part of the block. Both halves of the bearings contain inserts made of sheet steel with an aluminium layer. The inserts have tongue locks and a central groove for lubrication.
The bearing caps are all the same, bearings 1, 2, 4, 5 have the same liners. The third bearing has a different liner, since the axial clearance of the crankshaft is set during installation using side guide washers.
