If you need to identify your chain then you need to know the following information.
Chain gauge is the drive link's thickness where it fits into the guide-bar groove. The gauge of the chain and the gauge of the guide bar must match. OREGON® has several gauges - such as .050", .063", etc.
Chain pitch is the distance between any three consecutive rivets divided by two. Pitch defines the size of the chain. OREGON® chain is made in several pitches - 1/4" is the smallest, 3/8" is the most popular. Other parts of the cutting elements are pitch-related. The drive sprocket must be the same pitch as the chain, and so must the nose sprocket in sprocket-nose bars.
Number of Links:
The number of drive links need to be counted. These are the teeth on the back of the chain shown below.
