Why Regular Engine Mount Maintenance is Necessary In The Defence Industry
Engine mounts play a crucial role in the smooth operation of all vehicle engines. These often-overlooked components are designed to secure the engine to the chassis, reducing vibrations, noise, and movement. However, like all vehicle components, engine mounts are subject to wear and tear over time. Ignoring the warning signs of a failing engine mount can lead to a range of problems, including reduced performance, increased cost for repair, and even safety risks. Delaying replacement can lead to engine misalignment, damage to other components, or even complete mount failure. Recognising the symptoms early and replacing worn mounts promptly prevents potential costly repairs which can be easily avoided.
At GMT Rubber, we supply crucial replacement parts for military vehicles including engine mounts. Anti-vibration products are essential for vehicles that are regularly exposed to extreme conditions. Engineers across the industry depend on a reliable supply and our products ensure crucial service vehicles have quality parts to keep engines running smoothly.
What is GMT Rubber’s role in the Defence Industry
Engine mounts might not demand attention as frequently as tyres or oil changes, but their role in vehicle performance and safety is undeniable. We have become a well-established supplier for the defence industry in the UK, equipping the British Army, Navy and Royal Airforce with crucial rubber parts for large machinery and military vehicles. High quality parts are essential in such a vital industry, ensuring safety and security for heavy-duty vehicles in active service.
How Often Do Engine Mounts Need Replacing?
The lifespan of an engine mount varies depending on factors such as driving conditions, the type of vehicle, and the quality of the mounts. Generally, engine mounts should be inspected regularly and replaced every 60,000 to 100,000 miles. For military vehicles that are often exposed to extreme terrains, tow heavy loads, or drive in extreme temperatures, this interval may be shorter. Regular vehicle maintenance is the best way to monitor the condition of engine mounts and address potential issues before they escalate.
10 Signs That An Engine Mount Needs Replacing
Engineers responsible on the ground for looking after military service vehicles will have a keen eye and ear for signs of a faulty engine mount. However, all vehicles make use of an engine mount including the car on your drive. Here are some signs to look out for.
1. Excessive Noise
If you hear clunking, banging, or knocking sounds when accelerating, braking, or driving over bumps, your engine mount may be failing. These noises occur when the engine shifts more than it should, indicating that the mount is no longer securely holding it in place. Ignoring these sounds can lead to more severe damage to the engine and other components.
2. Excessive Vibration
Engine mounts are designed to isolate vibrations and provide a smoother ride. When they wear out, their ability to dampen these vibrations diminishes. This leads to noticeable shaking in the cabin, especially at idle or low speeds. This is one of the most common and uncomfortable signs of a failing engine mount, and addressing it promptly can restore a smoother driving experience.
3. Start-Up and Shut-Down Movement
During engine start-up or shut-down, you may notice a dramatic lurch or excessive movement from the engine. This happens when a weakened or broken engine mount can no longer stabilise the engine properly. Start-up and shut-down forces are particularly hard on worn mounts, and replacing them is crucial to avoid further strain on the engine.
4. Engine Misalignment
A misaligned engine can cause a host of problems, including uneven wear on drivetrain components and reduced fuel efficiency. When engine mounts deteriorate, they lose their ability to hold the engine in its proper position. Misalignment often manifests as poor handling or unusual noises, making it a key sign that replacement is needed.
5. Rough Gear Shifting
If your vehicle’s gear shifts feel rough, clunky, or unresponsive, the problem could be related to failing engine mounts. A misaligned engine or excessive movement caused by worn mounts can disrupt the smooth operation of the transmission, particularly in vehicles with manual gearboxes. Addressing this issue through an engine motor mount replacement can restore normal gear-shifting performance.
6. Excessive Engine Movement
Excessive movement of the engine, visible under the bonnet, is a tell-tale sign of a failing mount. You might notice this during acceleration, braking, or cornering. This additional movement can place stress on connections, hoses, and wiring, leading to more significant damage if left unchecked.
7. A Rough Ride
A rough or unstable ride, even on relatively smooth roads, can point to failing engine mounts. Without functional mounts to isolate the vibrations and shocks generated by the engine, these forces are transferred to the chassis and felt throughout the vehicle. Replacing the mounts can greatly improve ride comfort.
8. Visual Wear and Tear on Engine Mounts
Sometimes, the best way to determine whether your engine mounts need replacing is by inspecting them. Visible cracks, corrosion, or deteriorating rubber are clear indicators that the mounts are no longer capable of performing their job effectively. Regular visual checks during routine maintenance can help catch these issues early.
9. Fluid Leaks
Many modern vehicles use hydraulic engine mounts that incorporate a fluid-filled chamber to improve vibration isolation. When these mounts wear out, the fluid can leak, reducing their effectiveness. If you notice fluid around the engine mounts, it’s a clear sign that they need to be replaced.
What Happens During Engine Mount Replacement?
As you can expect, replacing an engine mount isn’t something that can be done easily. Mechanics need to hoist the engine from the chassis in order to remove the faulty mount and replace the part. The engine mount replacement time typically ranges from 2 to 4 hours, depending on the vehicle’s design and the number of mounts being replaced. Usually, mechanics will use the opportunity to service the engine and look for any other anti-vibration parts that could do with replacement.
Why Do Engine Mounts Need Timely Replacement?
Delaying engine mount replacement can lead to more significant issues down the road, including damage to the transmission, exhaust system, or chassis. Worn mounts can also compromise vehicle safety, as excessive engine movement increases the risk of dislodging vital components. Addressing the problem promptly ensures the service vehicle continues to operate safely and efficiently, reducing the likelihood of costly repairs in the future.
FAQs
Common signs include excessive vibrations, clunking noises, visible wear, fluid leaks, and rough gear shifting. Addressing these issues early can prevent more severe damage.
Engine mounts typically last between 60,000 and 100,000 miles, but factors such as driving conditions and vehicle usage can influence this interval.
Commercially, the price to replace engine mounts ranges from £150 to £500, with labour costs being a significant factor. Hydraulic and transmission mounts may cost more.
The complexity of the engine layout, the accessibility of the mounts, and the number of mounts being replaced all impact the replacement time, which usually takes 2 to 4 hours.
In the automotive industry, transmission mount replacement costs are often higher due to additional labour and complexity, with prices ranging from £300 to £700 on average.
Cracked or deteriorated rubber significantly reduces a mount’s ability to absorb vibrations, increasing engine movement and the risk of damage to other components.
