I'm doing some bearing replacement while I have my oil pan off (replacing oil pump). Original '92 C1500 5.7 with 162k. I'm in the process of removing the bearings, and checking the crank journals. The 1st main bearings and journal are worn and have some scoring. The other mains look ok, but I'll still replace the bearings. Have only removed #1 & #2 rod caps, those have some scoring, but I was able to tidy up the journal quite well. At this time, I am not interested in pulling the engine, or replacing it, just a basic repair.
Here is what I want to know. For an older crankshaft with nominal wear, what size bearings should I go for? Regular, undersize, or what? Any suggestion for measuring tools that will work with engine in place?
