HOW TO IDENTIFY A TIMING BELT
There are several ways that a timing belt can be identified. Many times the timing belt part number and the name of the timing belt manufacturer will be printed on the timing belt and will still be legible. While this is the ideal situation, there are many times when the timing belt part number is either incomplete, vague, or from a belt manufacturing company that is either out of business or has a timing belt numbering system that isn't easily cross referenced. If the timing belt isn't marked adequately, there are times when the timing pulleys are marked adequately to determine the pitch and profile of the timing belt. The pitch of the timing belt is the distance from the center of one tooth to the center of the next tooth. The problem is that there are several different tooth profiles or shapes for 3mm, 5mm, 8mm and 14mm pitches not easily discernible without proper tooling. These include the Conti AT5/T5, HTD/ STD, Power Grip HTD/ Power Grip GT2 and Poly Chain prof
