• Q: What is the Role of Rod Bearing in Measuring Crankshaft Bearing Clearances with Plastigage on 2007 Chrysler PT Cruiser?

  A: It is important to measure engine crankshaft bearing clearances using Plastigage or its equivalent. Before checking the precision, make sure the oil film on the surface is removed, since Plastigage is dissolved by oil. Next, put some Plastigage at the center's edge of both bearing shells in the cap, 6.35 mm (1/4 in.) off center and beyond the oil holes; repeated checks can be done on suspected surfaces. Place the bearing cap/bed plate bolts into the correct torque settings. Once the bearing cap is off, line up the flattened Plastigage with the scale on the package and find the matching band to learn the clearance in thousandths of a millimeter. If the diameter at the ends is different, it reflects the degree of taper, so make note of it and keep all your notes clear. Verify that the clearance in the engine is compatible with the numbers given in the engine manuals. You will usually find both inches and metric scales printed on Plastigage. There are different clearance ranges, so pick the one that lines up with your checklist. After that, add the correct crankshaft bearings to achieve the correct clearance specified by the engines' guidelines.
