Typical example
Install upper main bearing (4) to upper main bearing cap (2). Ensure that the locating tab for the main bearing is seated in the slot in the main bearing cap. Note: The upper bearing has a groove.
Install lower main bearing (5) to lower main bearing cap (6). Ensure that the locating tab for the main bearing is seated in the slot in the main bearing cap. Note: The lower bearing is a plain bearing that has oil holes.
Lubricate main bearings (4) and (5) with clean engine oil.
Illustration 2 g01327056
Typical example
Position the upper half of main bearing cap (2) in position on the crankshaft. Position the lower half of main bearing cap (6) in position on the crankshaft. Ensure the correct location and orientation of the bearing caps. The locating tabs for the upper and the lower bearings should be on the same side of the engine. Ensure that dowels (8) are in the correct position. This will ensure that the two halves of the main bearing caps are aligned. For C1.5 engines, install thrust washers (7).For C2.2 engines, install thrust washers (3) and (7).Note: Ensure that the thrust washers are aligned correctly and that the oil grooves are facing the crankshaft.
Install bolts (1). For C0.5, C0.7, C1.1, and C1.6 engines, tighten the bolts to a torque of 23 N m (17 lb ft).For C1.5 and C2.2 engines, tighten the bolts to a torque of 52 N m (38 lb ft).Crankshaft Bearing (Front)
