What does a go no go feeler gauge do?

Go/no-go feeler gauges are designed to simplify the interpretation of the clearance or gap value by reducing the need to rely on the user’s “feel” of the gauge, instead bracketing the clearance or gap value with a greater than/less than tolerance window.

What happens when the feeler gauge is too wide?

If the gap or clearance is too wide, combustion gases may escape during compression, reducing the engine performance. To make certain that gaps and clearances are within specified limits, engineers, mechanics, and machine operators rely on the use of measuring devices such as a feeler gauge.

When to use a feeler gauge in a Mating Machine?

Feeler gauges find application wherever there is a need to accurately establish the size of the clearance or gap between two mating machine elements or surfaces and where other measuring devices, such as calipers or a steel rule, are not able to be employed.

How to feel a feeler Guage on an adventure rider?

Some of the newer multi valve motors with the ti valves have such light pressure from the valve springs that you can easily push bigger gauges through, which makes feeling drag very difficult. I n those cases when I think I’m close I also try to spin the bucket with the gauge in place. Click to expand…

What’s the difference between a head and feeler gauge?

The clearance measurement itself is essentially the same as a head with rockers, except that you slide the blade of a feeler gauge between the cam lobe and the tappet instead of the rocker and the top of the valve stem. Stepped or so-called “go, no-go” feeler gauges are incredibly useful for valve adjustment.

What’s the best way to feel a Guage?

This can almost be practiced by holding a piece of paper between your thumb and index finger and with the other hand using the same fingers pull the paper and adjust the pressure with the fingers to feel the difference between a light drag and a tighter drag/squeeze.
