The Ultimate Guide: How to Change Gear Oil Aerox 155 Like a Pro

The Aerox 155 is a popular and powerful scooter, known for its performance and agility. Just like any other vehicle, it requires regular maintenance to ensure smooth operation and longevity. One crucial aspect of this maintenance is changing the gear oil.

This guide will walk you through the process of changing gear oil on your Aerox 155, providing a detailed explanation of each step. Whether you’re a seasoned mechanic or a first-time DIY enthusiast, this comprehensive guide will equip you with the knowledge and confidence to tackle this essential maintenance task.

Why Change Gear Oil?

Gear oil plays a vital role in the smooth functioning of your scooter’s transmission. It lubricates the moving parts, reducing friction and wear, and dissipates heat generated during operation. Over time, gear oil degrades due to heat, contamination, and mileage. This leads to increased friction, reduced performance, and potential damage to the transmission.

Here are some telltale signs that your Aerox 155’s gear oil needs changing:

• Rough shifting: If you experience difficulty shifting gears or notice a grinding sound, it’s a clear indication that the gear oil has lost its viscosity and is no longer effectively lubricating the gears.
• Metallic noise: A metallic clunking or rattling sound coming from the transmission area is a sign of increased wear and tear due to insufficient lubrication.
• Dark or cloudy oil: When you check the gear oil level, if it appears dark or cloudy, it’s a sign of contamination and degradation.
• Excessive wear and tear: If you notice excessive wear on the gears or other transmission components, it’s a sign of neglected gear oil changes.

Preparing for the Gear Oil Change

Before you begin the gear oil change, ensure you have the following materials and tools:

• New gear oil: Use the recommended gear oil for your Aerox 155. Refer to your owner’s manual for the correct viscosity and type.
• Drain pan: A suitable container to collect the old gear oil.
• Torque wrench: To tighten the drain plug and fill plug to the specified torque.
• Wrench: To loosen and tighten the drain plug and fill plug.
• Gloves: To protect your hands from the hot oil.
• Rag: To clean up any spills.
• Funnel: To pour the new gear oil into the transmission.

Step-by-Step Guide to Changing Gear Oil

Now that you have all the necessary materials, let’s get started with the gear oil change:

1. Warm up the engine: Start your scooter and let it run for a few minutes to warm up the gear oil. This will make it easier to drain.
2. Locate the drain plug: The drain plug is typically located on the bottom of the transmission case. It may be a hexagonal or square-shaped plug.
3. Loosen the drain plug: Using a wrench, carefully loosen the drain plug. Be cautious as the oil will be hot.
4. Drain the old oil: Once the drain plug is fully removed, allow the old oil to drain completely into the drain pan.
5. Clean the drain plug: Use a rag to clean the drain plug and the surrounding area to remove any debris or oil residue.
6. Replace the drain plug: Reinstall the drain plug and tighten it to the specified torque using a torque wrench.
7. Locate the fill plug: The fill plug is usually located on the side of the transmission case. It may be a hexagonal or square-shaped plug.
8. Remove the fill plug: Use a wrench to remove the fill plug.
9. Fill with new gear oil: Using the funnel, slowly pour the new gear oil into the transmission until it reaches the level of the fill plug hole.
10. Replace the fill plug: Reinstall the fill plug and tighten it to the specified torque using a torque wrench.
11. Check the oil level: Start the scooter and let it run for a few minutes to allow the oil to circulate. Then, check the oil level again. If it’s low, add more oil until it reaches the level of the fill plug hole.
12. Wipe up any spills: Clean up any oil spills with a rag.

Maintaining Your Scooter’s Transmission

Changing your Aerox 155’s gear oil regularly is crucial for maintaining the health of your scooter’s transmission. Here are some additional tips to keep your transmission running smoothly:

• Check the oil level regularly: It’s a good practice to check the gear oil level every few rides, especially after long journeys.
• Use the correct gear oil: Always use the type and viscosity of gear oil recommended by the manufacturer.
• Avoid overfilling: Overfilling the transmission can lead to excessive pressure and damage to the seals.
• Avoid harsh shifts: Shifting gears smoothly and avoiding abrupt movements can help minimize wear and tear on the transmission.
• Don’t neglect maintenance: Regularly check and maintain other transmission components like the clutch and belt to ensure optimal performance.

Beyond Gear Oil: Other Essential Maintenance Tasks

While gear oil is a vital aspect of your Aerox 155’s maintenance, there are other essential tasks that you should perform regularly to keep your scooter running smoothly. These include:

• Engine oil change: Just like gear oil, engine oil needs to be changed regularly to lubricate the engine and prevent wear and tear.
• Air filter cleaning or replacement: A clean air filter ensures optimal airflow to the engine, improving performance and fuel efficiency.
• Spark plug inspection and replacement: A worn-out spark plug can affect your scooter’s starting and performance.
• Tire pressure check: Maintaining the correct tire pressure ensures optimal grip and handling.
• Brake pad inspection and replacement: Worn-out brake pads can compromise your braking performance and safety.

The Importance of Regular Maintenance

Regular maintenance is essential for extending the life of your Aerox 155 and ensuring a smooth and enjoyable riding experience. By adhering to a routine maintenance schedule, you can prevent potential problems, minimize repairs, and maximize the performance and reliability of your scooter.

Final Thoughts: Your Aerox 155’s Longevity Starts with You

Changing gear oil on your Aerox 155 is a simple yet crucial maintenance task that can significantly impact the longevity and performance of your scooter. By following the steps outlined in this guide, you can confidently perform this task yourself and ensure that your scooter’s transmission operates smoothly for miles to come.

Remember, regular maintenance is key to enjoying a trouble-free and enjoyable riding experience. So, make it a habit to check and maintain your Aerox 155 regularly, and you’ll be rewarded with a reliable and high-performing scooter for years to come.
