    Bearing Clearance check By Using Plactic Gauge

    Greeting everyone. What happens if we use wrong class of plastic gauge. For example, the clearance given 0.175mm to 0.25mm, but we use different class of plastic gauge such as type c. Is the result from upper bearing housing compression will be different if use different plastic gauge? Sorry...
