The primary functions of an engine mount are to attach an engine to machinery and to withstand any vibrations and shocks that occur while the machinery is in use. An engine mount’s anti-vibration properties are critical for stopping engine problems and increasing operator comfort (where applicable). But what happens when the motor mounts need to be replaced? And how do you know when it’s time to replace them? In this article, we will answer both of these questions.
What Would Happen If I Don’t Replace My Engine / Motor Mounts?
Motor mounts, regardless of quality, begin to wear down after use and must eventually be replaced. Failure to replace an engine mount that has reached the end of its useful life can cause engine harm, operator discomfort, and, if the engine is not protected, a safety risk.
How long will motor mounts be expected to last?
Motor mounts can typically last at least 5-7 years, based on the application but we suggest having them checked over on a regular basis when the vehicle is serviced, or some other work is performed.
When should engine / motor mounts be replaced?
Being mindful of the following symptoms of a worn engine mount will assist you in determining when they need to be replaced:
If you start your car and hear it makes more noise than normal, or if you feel more noises than usual, this is a symptom of a deteriorated engine mount that needs to be replaced. The anti-vibration characteristics of an engine mount deteriorate when it is damaged. A rise in vibrations causes the engine to make more noise than normal, which can be highly harmful to an engine if it lasts for an extended period of time.
When you start a vehicle, you can find an abnormal lurch which does not feel or sound good. This is a typical symptom of a defective or broken engine mount. This lurch sometimes settles into a steady vibration, but you can often feel a lurch when switching off the ignition.
A More Difficult Ride
Usually, Engine mounts that need to be replaced will frequently trigger a jolt when shifting gears on an attached transmission. This jolt or thump is often apparent at higher speeds due to the engine trying harder. If your machine isn’t as smooth as it used to be, it may be due to a broken engine mount.
A worn engine mount will frequently cause ‘clunking noises’ and ‘bangs’ in its surroundings/engine hold. This is due to the engine shifting around more than usual and coming into contact with other parts, which can result in audible impact vibrations.
The metal portion of an engine mount changes appearance with use. However, if you notice any substantial corrosion, cracks, or warps in the component, the rest of the mount will most likely be subjected to excessive wear. If you find any cracks or flaking on the rubber component of an engine mount, depending on the extent of the cracks and the route cause, this may potentially restrict its efficiency. Motor mounts’ effectiveness is dependent on their type and shape; any changes to these can be harmful to the engine. If you experience any of these symptoms, you can replace the motor mounts as soon as possible.
