Remove the engine oil pump.
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat® products.Dispose of all fluids according to local regulations and mandates.

Check main bearing caps (1) for identification marks for the location. The main bearing cap (1) has an arrow on the cap which points to the front of the cylinder block. Each main bearing cap (1) has a number on the cap for the location.
The removal of the main bearing caps for the 3408 and 3412 engines
For the 3412 engine, remove No. 2 through No. 6 main bearing caps (1) from the engine. Remove the lower bearings from the caps.
Repeat the process in order to remove No. 1 and No. 7 main bearing caps (1).
Remove the thrust plates from each side of the No. 4 main bearing.
For the 3408 engine, remove No. 2 through No. 4 main bearing caps (1) from the engine. Remove the lower bearings from the caps.
Repeat the process in order to remove No. 1 and No. 5 main bearing caps (1).
Remove the thrust plates from each side of the No. 3 main bearing.

If the crankshaft is turned in the wrong direction, the tab of bearing will be pushed between the crankshaft and the cylinder block. Doing so will damage to the crankshaft and block.
Turn the crankshaft until Tooling (A) can be installed in oil hole (2). Turn the crankshaft in the direction which will remove the upper main bearing. Installation Procedure

Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Illustration 3 g00503404Note: Ensure that the main bearings are installed so bearing tabs (3) fit into the notch in the cylinder block and in the main bearing caps.Note: Install the main bearings without lubricant when the check for the crankshaft main bearing clearance is made. Put clean engine oil on the crankshaft main bearings for final assembly.

Install the upper halves of the main bearings in the cylinder block with Tooling (A).
Install the lower bearings in the bearing cap.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. Doing so well get a correct measurement with Tooling (B). If the crankshaft is not supported, the weight of the crankshaft will cause an incorrect reading. If the engine is inverted then it is not necessary to hold the crankshaft upward. Do not rotate the crankshaft when Tooling (B) is installed.Note: Refer to Guideline For Reusable Parts, SEBV0544, "Engine Bearings and Crankshafts" for complete details concerning measuring of bearing clearances.
Use Tooling (B) to check the crankshaft main bearing clearances. Follow Steps 5 and 6 for the correct installation procedures and tightening procedures for the main bearing caps when the clearance check is performed. Refer to Disassembly and Assembly, "Bearing Clearance - Check".Bearing clearance (new bearings) ... 0.091 to 0.186 mm (0.0036 to 0.0073 inch)Maximum permissible bearing clearance (used bearings) ... 0.25 mm (0.010 inch)
