The Necessity of Motorcycle Wheel Balancing

When comes to motorcycle tyre replacement, many individuals just mount the tyre on the wheel hub and use it immediately. They refuse to go to the balancing machine to perform any motorcycle wheel balancing tests. This article will explain why it is necessary to balance motorcycle wheels.

One possible explanation for this is that they are unaware of how crucial two-wheeler wheel balancing is. However, the whole scenario is rather easy due to the lack of equipment, and balancing two-wheeler wheels is not possible.

What then is wheel balancing on a motorcycle? Do motorcycle tyres require dynamic balancing? The definition and significance of motorcycle wheel balancing are explained in this article.

What is Motorcycle Wheel Balancing?

The process of counterweighting so that the wheel adjusts the balance of each edge component is known as motorcycle wheel balancing. Counterweight = wheel balance

There is some degree of mass variation in the tyre and rim mass distribution because of the manufacturing process used to make motorcycle tyres. There are also little lead bumps on the new vehicle wheels because the static balance can still be adjusted at this time.

As a matter of fact, throughout the manufacturing process of tyres and wheels, there will be a weight imbalance that, while not immediately apparent at moderate speeds, will result in vibrations in the handlebars and shaking wheels at high speeds. To prevent this, we must add lead to the hub to modify the wheel counterweight. Dynamic balancing is the process of determining equilibrium on a rolling wheel.

Does wheel balance for motorcycles have to be done?

Vehicles tend to have more balancing, and many individuals learn how important it is only after they have an accident while driving. In actuality, dynamic balance tests are also required for motorcycles.

Additionally, individuals frequently overlook the issue of motorcycle wheel balancing. Motorcycle tyre specifications such as tyre pattern, tyre pressure, wear level, etc. are the main focus. At high speeds, motorcycles with unbalanced wheels will feel as though they are floating in midair.

In extreme circumstances, when cornering, the back wheels will wobble and slide sideways. Uneven tyre wear is caused by the continuous cycling of motorcycle tyres while driving, which involves abrupt acceleration and braking.

When is motorcycle wheel balance necessary?

The front and rear tyres are slanted to one side after mounting or repairing them after a motorcycle crash.

When driving, the handlebars sway and tremble or are excessively heavy.

The motorcycle veers left or right when traveling straight. While there is no such thing as a condition of this kind, it is advised that the new motorcycle be driven for three months, and then every six months or two thousand kilometers for maintenance purposes.

The risk of failing to do the motorcycle wheel balancing

At high speeds, the vehicle will vibrate excessively. The motorcycle shock absorber and the rider’s various body parts absorb the impact force produced by the tyres hitting the ground.

Frequent vibrations can shorten component life by producing wear and slack in bearings and suspension systems. They can even break and cause wheels to come off.

If there is no dynamic balance support for fast motorcycles, the shaking will be noticeable when driving at high speeds and will impair control. The vehicle body feels as though it is floating in midair, and if a tyre is not spherical, the wear on its outside and inside will differ.

It will slip sideways when turning, and at the end, unanticipated mishaps might happen. However, these risks can be avoided if lead is applied to the wheel (to balance the motorcycle’s wheel), even though it only adds a few grams or a dozen grams of weight.

The advantages of completing the motorcycle’s wheel balancing

Make driving more comfortable

Use less fuel.

Prolong the lifespan of your tyres

Verify that the vehicle is stable when traveling straight ahead.

Lessens abrasion on the chassis suspension components

Boost traffic safety

At least once a month, vehicle owners should check the pressure in all of the tyres, and when inflating tyres, they should compare the results to the recommended tyre pressure. Wheel imbalance can also be caused by anomalous tyre wear, which can be accelerated by either too high or too low tyre pressure.

Safety measures to take when doing wheel balancing on a motorcycle

When balancing the wheels of a motorcycle, there are a few general considerations to consider:

For dynamic balance, use new tyres—ideally, ones with a low flatness rate.

Avoid switching to old tyres and collisions after balancing.

The dynamic balance test for motorcycles is only suitable for tyres that are mounted on alloy wheels.

Why don’t some motorcycles balance properly?

Motorcycles that have a displacement of less than 150 and a design speed of less than 100 km/h are referred to as certain motorcycles. When I changed the tyre, I neglected to conduct the balancing.

Actually, you can make the tyre counterweight depart very little within the design speed as long as you switch to ordinary tyres. It’s not that you don’t want to do it.

There is no installation of a counterbalance and some tiny repair shops do not utilize original tyres. Therefore, after traveling at 60 km/h, there will be a noticeable vibration throughout the entire vehicle, which is also a sign that the tyre is not performing dynamic balancing.

The idea is to replace the original tyres and install the tyres strictly in compliance with the standards, which can practically create the dynamic balancing effect even if this kind of vehicle cannot be dynamically balanced.

Conclusion

Motorcycle wheel balancing is a maintenance task that needs to be completed whenever a tyre is reassembled, but many people are unaware of its significance or the need to find the solution. Unbalanced wheels lead to uneven tyre wear, etc., and riding comfort can be significantly impacted by not adjusting wheel balance.

From Scrap to Metal

Aluminium is one of the most sought-after metals and is used in high volumes across multiple industries, including defence, transport, construction, food & beverages, and electronics. But extraction of pure aluminium from the bauxite ore is quite expensive and hence shoots up the manufacturing cost of the end products. Additionally, cheap imports of aluminium products from the foreign markets put pressure on India's domestic rolled products industry. With India’s annual aluminium consumption projected to double by 2023 to 7.2 million tons, there is a dire need for an alternative to this.

Solution: Secondary Aluminium!

The large-scale demand and usage of aluminium, generates massive amounts of scrap. This scrap serves as the source for the secondary aluminium! It comprises around 30% of India's total aluminium consumption of 3.3 million tons annually. Recycling aluminium is environmentally friendly, as the process consumes 95% less energy than generating primary aluminium. And since the atomic structure of aluminium remains unaltered upon melting, it enables the usage of the molten metal for various applications. It has been observed that the demand for secondary aluminium has grown faster than primary aluminium due to better cost economics, especially in the price-sensitive automotive castings sector. 

Our customer who is India's largest producer of aluminium and zinc die-casting alloys, has been tapping the potential of India's aluminium recycling industry.  From setting up its first plant in Tatarpur, near New Delhi, our customer’s expanse has grown to 12 plants across the country. These plants have a combined annual capacity of approximately 310,700 MT, making it the Rank One nationally in aluminium and zinc die-casting alloy production!

The plants have collection, segregation, processing, recycling, and treatment facilities for all types of secondary metal raw materials. The group also has joint ventures with renowned Japanese companies such as Toyota Tsusho Corporation and Nikkei MC Aluminium. Its most recent joint venture is for a plant in Gujarat, where the recycling of end-of-life vehicles (ELVs) is conducted through dismantling, shredding, and sorting.

Generating value for customers is the focus of the business, and there is constant attention to improving quality, controlling costs, and streamlining delivery. To ensure compliance with industry norms, the group has acquired ISO 14001, TS16949, 45001, and OHSAS 18001 certifications, along with other research and development certifications.

Our customer has a technology-focused approach in all its processes, making business activities more cost-effective and environmental-friendly.

Following are the steps involved in converting scrap metal into molten metal:

Manufacturing

Various steps are deployed to improve metal recovery rates while saving fuel costs. High-pressure hot air is used to vaporize ink from the surface, regenerative burners heat the metal, de-coaters remove the scales to reduce dross, and furnace circulation maintains temperature.

Segregation

Segregation is a critical step that ensures no impurities or contaminants enter the furnace. The process is mechanized using floatation systems, induction-based sorting systems, colour sorters, rotary sieves, eddy current separators, gravimetric separators, and shredders. Combining these pieces of equipment helps maintain the quality of the recycled aluminium.

Delivery

The molten metal obtained at the end of the process meets industry standards and is ready for delivery. However, specially designed ladles and trucks are used for transportation, as it is necessary to maintain the temperature of the molten metal during transit. Anti-pollution control mechanisms and baghouses are also used to reduce harmful emissions.

The Stumbling Block

Despite the smart energy-saving techniques, our customer’s non-ferrous recycling plants needed high-quality air processors to ensure that each shred of aluminium was free from contaminants and decorations before being added to the furnace. This was critical because the foreign particles could disrupt the quality of the aluminium recycled and would also increase fuel costs.

So, the challenge was to deploy an air system that could provide the highest quality of hot air as it would directly impact the product quality and cost.

Compressed air solution by ELGi

Our customer decided to install EG 22, EG 30, EG 37, EG 55, and EG 110 models of ELGi Screw Compressors across all their plants.

Each compressor was enabled with DCS and SCADA remote monitoring to ease operations. Additionally, every compressor met the highest air purity standards as per ISO regulations, maintaining a constant flow of hot air while ensuring the raw material was contaminant-free. In short, ELGi's EG Series Screw Air Compressors ensured that the metal recycling plants processed more shreds of aluminium at a much faster pace and that too with least downtime.

Additionally, ELGi provided installation & maintenance services for all compressors. We also provided preventive maintenance along with it. However, given the robustness of the EG series, no breakdowns were reported at any plant thus resulting in minimal downtime.

The ELGi Advantage:

Decontamination of raw material: High-quality air helped the brand conform to industry standards and deliver the accurate aluminium composition to its customers.

Cost control: Decontaminating raw materials reduced fuel consumption and energy costs.
