How are timing belts connected to the crankshaft?
By definition a timing belt is a toothed belt that connects the camshaft or shafts to the crankshaft thus “timing”the top and bottom of the engine. The camshafts turn at exactly ½ of the speed of the crankshaft to time the valve operation to the piston operation.
When did the first timing belt come out?
Originally made of a band with metal clips this proved to be expensive and noisy, in 1945 Singer in conjunction with Uniroyal which is now Gates Inc. developed the timing belt. Now to all you guys from the 50’s and 60’s typically every engine had a timing chain.
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.
How much does it cost to replace timing belt on Nissan Xterra?

Where is the timing belt on a transverse 4 cylinder engine?
On most transverse four-cylinder engines, you’ll have to remove the passenger-side motor mount in order to gain access to the timing belt. This means the entire powertrain needs to be supported in that area while you’re working. And finally, getting to the lower portion of multipiece timing belt covers usually requires underbody access.
How long do timing belts last on econobox?
How we test gear. Timing belts last 60,000 to 100,000 miles. check your owner’s manual for the manufacturer’s replacement interval. Your six-year-old econobox is starting to show a bit of wear and tear, but everything mechanical still works fine. Until it doesn’t. Specifically, the engine suddenly goes dead silent one fine day.
