How Long Do the Timing Gears Last?

The timing gears work with the timing belt and chains in the engine to ensure your vehicle runs smoothly. The gears are connected to the crankshaft at one end and the camshaft at the other end. They have small increments around it, which correspond to the degrees of timing. The marks help the mechanic who is tuning up the engine to ensure the correct timing of the parts and ultimately the best timing of the camshaft and engine.

The purpose of the timing gears is to control how much fuel and air enter the cylinder. They do this by firing the spark plugs, closing the valve, and release exhaust fumes all at the correct timing according to how the belt moves. The gears are durable as they are made from aluminum or steel materials. While they do last a long time, they normally do not last the lifetime of your vehicle.

Over time, the gears can become chipped, damage, or fail because they work hard on a regular basis. Every time you turn your vehicle on, the timing gears are engaged and work until your vehicle is turned off. They are an important part to your engine running smoothly, so if you suspect an issue with your timing gears, contact a professional mechanic to have the timing gears replaced.

If the gears are off when the engine is assembled or after the timing gears are replaced, the vehicle will not run well. If the timing is off by as little as two teeth, the engine may not run at all.

Since this part can go bad and fail over time, it is important to recognize the symptoms that indicate it needs to be looked at by a mechanic soon.

Signs that point toward your timing gears need to be replaced include:

  • The engine starts but the vehicle runs poorly after it is started

  • Noise from the engine or front of the vehicle

  • The engine does not turn on at all

  • The engine backfires on a regular basis

The timing gears are an essential part of your engine, therefore, this repair should be completed as soon as you start noticing symptoms.

Omari arrived on time and introduced himself, he was ready to get started to work. He checked the car over and began the task of replacing the PCV valve and hose' Omari was efficient and got the job done. He was pleasant and informed me of other items that will soon need attention he even wrote me a quote right away. I have not driven the car since the repair but will do so in the next day or two.

Richard was very professional and able to come to our house on a Sunday as well. We scheduled for 4 brakes and rotors and he told us that we actually didn’t need it to be worked on. If we would of gone to a shop or a dealer they would probably have changed it for us if we didn’t even need it. We are thankful for that Richard saved us money with that Information we are looking forward to working with him again on our other cars.
