6-82 Marine/Industrial 4.3L Engine 188015 Micrometer Method for Connecting Rod Bearings Notice: Do not shim, scrape or file bearing inserts. Do not touch the bearing surface of the insert with bare fingers. Skin oil and acids will etch the bearing surface. 1. Measure the crankpin diameter with a micrometer in several places, approximately 90 degrees apart, and then average the measurements. 2. Determine the taper and the out-of-round. Refer to Engine Mechanical Specifications. 3. Install the connecting rod bearings into the connecting rod cap and the connecting rod. Notice: Refer to Fastener Notice in Cautions and Notices. 4. Install the connecting rod caps and the nuts. Tighten 4.1. Tighten the connecting rod nuts on the first pass, evenly to 27 N•m (20 lb ft). 4.2. Tighten the connecting rod nuts on the final pass an additional 70 degrees using the J 36660. 5. Measure the connecting rod bearing inside diameter (ID) at the top and the bottom using an inside micrometer. 6. Compare the connecting rod bearing clearance to the specifications. Refer to Engine Mechanical Specifications. 7. If the connecting rod bearing clearance is within specifications, the connecting rod bearing is satisfactory. • Replace the connecting rod bearing if the clearance is not within specifications. • Always replace both the upper and the lower connecting rod bearings as an assembly. 8. A standard or undersize connecting rod bearing combination may result in the proper clearance. If the proper connecting rod bearing clearance cannot be achieved using the standard or the undersize connecting rod bearings, it will be necessary to replace or repair the crankshaft. 2000 Marine/Industrial
