What do you need to know about timing belts?
Downloadable/printable Timing Belt Tooth Profiles and Pitches (.pdf) Note the shape of the timing belt pulley teeth (tooth profile); if the valley between the teeth is curved than it is an HTD style timing belt. If the valley between the teeth is flat than it is and PolyChain GT style timing belt.
How do you measure a timing belt pulley?
There should be two (2) measurements for this since the majority of timing belt drives has a means in place for tensioning the belts. The two distances required will have one of the shafts in the all the way forward position and the other in the all the way backward position. Count the number of teeth on both timing belt pulleys.
What is the difference between rubber and polyurethane timing belts?
Note the construction of the timing belt. Rubber construction is extremely flexible while a polyurethane construction is plastic like and has little flexibility Measure the pitch (see diagram). This is the distance in millimeters (mm) and/or inches between the center of the crown of one tooth and the center of the crown of the tooth adjacent to it.
How to identify a polychain GT style timing belt?
If the valley between the teeth is flat than it is and PolyChain GT style timing belt. You should also look for identifying numbers and/or letters on the pulleys themselves to help in the timing belt tooth profile identification.
Why do people talk about the timing belt?
Most car owners who know something about cars have heard about the timing belt. It is probably the car part which is most talked about. This is probably because of the expensive replacement cost and the disaster which happens if it snaps off.
How long does it take to replace timing belt?
