To determine the pitch (chain size), you'll need to measure the distance between any three consecutive rivets, then divide the result by 2. The rivets are the small, round pegs/studs that hold the chain segments together. Measure from the first to the third, then divide that number in half to get your chain pitch.

Also question is, how do you read a chainsaw chain?

A chain is secured on a chainsaw by drive links which fit into the tool's guide bar. You'll find the drive links on the bottom of the chain, opposite the cutting teeth. The gauge of your chain is simply how thick the drive links are.

Furthermore, can you put a chainsaw chain on backwards? Unfortunately the chain will go on either way, but if you put it on backwards, it will not cut.

In this way, how do you measure the bar and chain on a chainsaw?

Measure the distance from the tip of the chainsaw bar to the point where the bar first emerges from the saw's casing. A tape measure will provide that information. Round the measurement up to the nearest even number if the figure was uneven or fractional. The resulting number is the bar measurement.

Do drive links matter on chainsaw?

Number of individual drive links must be counted. No exceptions. Simple length measurements (like "a 2 foot chain) are not helpful for correctly matching chains. Chain length is determined by a combination of distance between links (pitch) and the number of links.

What angle do you sharpen a chainsaw?
