How to choose the right timing belt drive?

TÐ146 SECTION 24 TIMING BELT DRIVE SELECTION PROCEDURE Step 1 Determination of design load Drives consist of a driver and a driven pulley. In general, both pulleys are not of the same size; therefore, a speed reduction or increase occurs. Both convey the same power; however, the torque on each pulley is different.

What happens when my timing belt fails while driving?

So, if you have an interference engine and the timing belt fails, the camshaft is not turning, and the valves will not open. The piston will still rise into the cylinder and then it will collide with the closed valve. This could damage the cam heads, the valves, the pistons, and essentially destroy your entire engine.

Why is the timing belt made of rubber?

The timing belt allows the valves to be opened and closed once every other revolution of the crankshaft. The belt is made of rubber and has fiber strands in it that provide it with extra strength. It is also lined with teeth to help prevent it from slipping.

How often should a Honda Pilot timing belt be replaced?

In spite of that, the datalogger shows that the average speed driven is about 30 MPH. It gets a belt and all the related wear parts every 7 years or 50-60k mines. The ones that come out look new except for a little buffing on the back where the tensioner and rollers contact it. They –look– new.

What happens when your car’s timing belt breaks?

It depends. Some cars, like Subaru, have non-interference engines, which means that if the timing belt breaks while you are driving, there is no damage to the internal parts of the engine. Other cars do not have this sort of engine and damage results.

How many miles should a timing belt last?

A timing belt should last at least 50K miles, so maybe the belt just came off. Still, damage could occur.

What should I do if my timing belt snaps?

At this point, the camshaft sprockets will align with the marks on engine, and the crank sprocket will align with the marks on the engine. Some engines, like GM interference DOHC V6s, will require special tools keep the cams from moving, so consult with a factory service manual if you can.

What happens if the timing belt snaps on an interference engine?

While it is possible that no damage could occur from a snapped belt on an interference engine, such a case is unlikely. In a non-interference engine, the pistons and valves don’t occupy the same space, so if the timing belt snaps, no valve or cylinder damage occurs.
