Jun 15, 2017 · This evening we are going to cover how to check your main bearing and connecting rod bearing clearances using Plastigage. Checking clearances is critical when building an engine and using new bearings to ensure that you are within tolerances for the bottom end components of the motor.

Plastigauge is highly effective for measuring the clearance in almost any bearing configuration or area that has hidden surfaces. Shaft end-float lends itself to direct measurement by Plastigauge. Flatness and clearance in pipe-flanges and cylinder heads are readily checked and measured with standard Plastigauge.

Plastigauge is extremely effective for measuring the clearance of a wide variety of bearings which include automotive/machine bearings, marine drive shaft bearings, turbine housing bearings, pump and pressure system bearings, as well as shaft end-float dimensions, flatness and clearance in pipe-flanges and cylinder heads.

Use Plastigauge to quickly and accurately measure clearances of rod and main bearings. Plastigauge is a precisely made thread of wax that spreads out to a predictable width as it flattens between your bearing surfaces.

How do I easily check the bearing clearance on the crankshaft and connecting rod? What is the maximum permitted bearing clearance? And what is the minimum bearing clearance? How are measuring strips used? When are oversize engine bearings used? …

Aug 4, 2020 · Every engine has its own bearing clearance specs, but the measuring procedure does not change. There are two main methods used for checking bearing clearance – Plastigage® or gauges. Plastigage® Plastigage® has its place, as it serves a purpose for backing up and verifying your bearing clearances.
