8. LUBRICATE BEARING SURFACES : Lubricate all bearing surfaces and rear lip seal with clean engine oil. We do not recommend the use of greases for this purpose. 9. CRANKSHAFT INSTALLATION: Gently and squarely place the crankshaft onto the main bearings. Care should be taken to prevent damage to the bearing flange thrust surfaces. Main caps and bearings must then be installed in proper positions. 10. TORQUE MAIN BEARING BOLTS: All bolt threads must be cleaned and lightly lubricated to obtain correct torque readings. Final tightening of all bolts must be in accordance with engine manufacturer's specifications. Crankshaft should rotate freely after tightening procedure. Check for proper oil clearance prior to final assembly of main bearings. 11. CONNECTING ROD INSTALLATION: Before installing piston and rod assemblies, rod bolt threads must be covered to prevent damage to crankshaft journals. 12. ROD CAP INSTALLATION: Match rod caps in accordance with cylinder numbers on connecting rods. Check for proper oil clearance prior to final assembly of the rod bearings. Torque rod bolts or nuts to manufacturer's specifications. 13. CHECK PROPER END CLEARANCE: By using a feeler gauge, check for proper end clearance between crankshaft thrust and bearing flange to manufacturer's recommendations. 14. PRIME ENGINE OILING SYSTEM: Before starting engine, oiling system must be primed to prevent dry start and damage to bearing surfaces |

1. IDENTIFY MATCHING PARTS: Before engine disassembly, all connecting rods and matching caps should be numbered according to cylinder location. Each main bearing cap should be numbered according to it's location in the block. 2. CHECK CONNECTING ROD HOUSING BORES: Connecting rod housing abores must be checked for roundness and size using bore gauges or inside micrometers. If the housing bore does not meet specifications, it should be reconditioned by a qualified machine shop. 3. CHECK MAIN BEARING BORES: With the engine block inverted, main bearing bores must be checked for alignment and size. If necessary, engine block should be reconditioned by a qualified machine shop before reuse. 4. CLEAN OIL PASSAGES IN CRANKSHAFT: Ensure that oil ways and holes are cleaned using a brush and compressed air. When using compressed air, be careful not to blow dirt onto previously cleaned surfaces 5. CLEAN OIL PASSAGES IN ENGINE: Thoroughly clean oil ways using compressed air and a brush. Be careful not to blow dirt onto previously cleaned surfaces 6. CLEAN MAIN BEARINGS AND BORES: Bearings and main bearing bores must be cleaned and dry. 7. CHECK OIL HOLE ALIGNMENT: Ensure bearing locating tang lines up exactly with recess in block and that oil feed hole lines up with hole or slot in bearing to ensure proper oil flow. |
