Note: Ensure that the main bearings are installed so that bearing tabs (3) fit into the notch in the cylinder block and in the main bearing caps.
Install new crankshaft main bearings in the main bearing caps.

The engine is inverted on 4C-9832 Engine Rollover Stand .Note: When the bearing clearance is checked and the engine is in an upright position or on a side position, the crankshaft must be supported against the upper halves of the main bearings. This is done in order to get a correct measurement with Tool (B). If the crankshaft is not supported, the weight of the crankshaft will cause an incorrect reading. If the engine is inverted it is not necessary to hold the crankshaft upward. Do not rotate the crankshaft when Tool (B) is installed.Note: Refer to Special Publication, SEBD0531, "Engine Bearings and Crankshafts" for complete details concerning measuring of bearing clearances.
Check the bearing clearances with Tool (B). Put Tool (B) on the bearing surfaces.

Note: Ensure that the numbers on the main bearing caps match the numbers on the cylinder block. The arrows (4) on the main bearing caps are toward the front of the cylinder block.Note: Install the thrust plates with the identification "Block Side" toward the cylinder block.
Install the main bearing caps for No. 2 through No. 6 main bearings. Put clean engine oil on the bolts. Install the bolts in the main bearing caps.
