TIMING BELT DIAGRAM HOW TO

If your timing belt is made of polyurethane, it will likely appear smooth and slick. Neoprene is usually black and bends easily. If your timing belt is made of neoprene, it will feel rubbery, flexible, and may flake apart with overuse. Your timing belt is most likely made of neoprene or polyurethane. You will also need to know the material of your timing belt. If you have been able to measure the pitch and ridge profile of your timing belt, you’ll be able to use these numbers to identify it based on its timing belt standard size. You may need a special tool to measure the pitch. It’s not always easy to measure this small of a distance. Ridges commonly come in many different shapes, or “profiles,” including 3mm, 5mm, 8mm, and 14mm pitches. In short, the timing belt’s pitch is the length from the top of one ridge to the top of the next ridge.

How to measure a timing belt’s pitch: The pitch is defined as the distance, in inches and/or millimeters (mm) from the center of the top of one of the ridges or teeth of the timing belt and the center of the top of the nearest ridge or tooth. You will need to take measurements of the timing belt’s width, length, and pitch to identify it if you don’t have a printed manufacturer name or letter and number combination. If there has not been a manufacturer name, nor a number or number and letter combination printed on the timing belt, you may be able to identify the timing belt manually through the following method: Measuring the Timing Belt’s Width, Length, and Pitch: Manually Identify the Timing Belt Through Another Method: (More information on what to do with this number and letter combination, if you have it, further down in this article!) 3. Some manufacturers will mark the pulley rather than the timing belt itself. If you didn’t see a complete or legible marking, or any marking at all, on your timing belt, check the timing pulley. The number and letter combination will look generally like “640-8MX-12,” for example, although your letters and numbers may differ. The number is key to identifying your belt’s specifics. While a letter/number combination is not easy to reference, the numbers and/or letters represent a standard trade size. Sometimes, manufacturers will leave behind a combination of numbers and letters that only they would be able to easily identify. Identify the Timing Belt by its Letter and Number Combination: Below is a list of common manufacturers you may see on your timing belt:Ģ.

However, in certain circumstances, you may find the print is no longer legible, or that printing its name on the timing belt was not the standard practice of the manufacturer. The manufacturer’s name should ideally be printed on the timing belt. Often, the timing belt you are seeking to identify will feature both A) a part number, and B) the name of the timing belt manufacturer. Identify the Timing Belt by Manufacturer Name:
