What tool is used to check bearing clearance on small engines?

The tool used to check bearing clearance on small engines is the Plasti Gauge. This material is a thin plastic strip that can be placed between the bearing and the journal surface. When the engine is operated, the Plasti Gauge compresses, allowing the technician to measure the clearance by using a chart that correlates the width of the compressed strip to the measurement of the gap.

Plasti Gauge is especially advantageous because it provides a straightforward means of measuring bearing clearance without the need for disassembling the engine or having highly calibrated tools. It is a simple yet effective method for ensuring proper engine assembly and function. Its design specifically caters to the requirements of measuring small clearances in a precise manner, which is crucial for the longevity and performance of small engines.
