The main bearing caps are made from cast iron and are cross bolted to increase rigidity. An identification mark on each bearing cap must face the front of the engine.
There are five grades of main bearing available, each being color coded. Journal sizes are marked on the rear of the crankshaft.
The thickness grade of all main bearing shells are to be selected to give a total running clearance of not less than 0.046mm or not greater than 0.067mm.
The main bearing shells in the cylinder block have a central hole and an internal groove to allow for main journal lubrication. The bearing shells in the main bearing caps are plain with no grooves.
Special tools are required to ensure the correct alignment of the upper and lower main bearing shells.
