hey, can someone explain to me what this is and how it works and how its done? im getting a little confused on how your supposed to do this and why its done.
You purchase plastigage at an auto parts store. It comes in a few sizes depending on the clearances you are measuring. If you take your service manual, the parts person will help you find the right size to purchase. The cost is minimal. Plastigage is an impregnated string that squishes when you insert it between the journal and bearing shell and torque the bolts down. The width that it squishes to is measured against a scale on the package to determine your exact clearance. Once you find this value, you can determine how much oversize will be required to bring the clearance back to that required by your manual. To use plastigage, cut a strip wide enough to go across the journal, reassemble the shell and cap with the strip placed across the journal, torque the bolts, and disassemble. You can then measure the surfaces against the package that the plastigage came in. Never turn the crank during this process.hey, can someone explain to me what this is and how it works and how its done? im getting a little confused on how your supposed to do this and why its done.
you plastigauge it with the new bearing, so that there is no wear.how do you know what bearing to put in there? the old one? on my last engine build i just used "green" or standards, on my next build should i get these and use that on the plastigauge to get proper bearing size?
