Motor graders like the Galion 118B are vital for road construction, grading, and earthmoving tasks. They are designed to withstand the most demanding conditions, often requiring maintenance and part replacements due to wear and tear. One common maintenance task is removing the rear wheels, whether for tire replacement, repairs, or inspection of the axle and brake components. While this may seem like a straightforward job, the process requires attention to detail to avoid damage to components and ensure safety.
Importance of Regular Maintenance for the Galion 118B
Motor graders are essential pieces of equipment for construction and mining projects. The Galion 118B, specifically, is well-regarded for its durability and reliability. However, just like any heavy machinery, the rear wheels and axles are subject to wear. A failure to address worn-out tires or damaged axle components can lead to decreased machine performance or even operational breakdowns.
Key Considerations for Wheel Removal
Before diving into the process of wheel removal, it's important to consider a few basic factors:
Removing and replacing the rear wheels on a Galion 118B motor grader is a straightforward task if done carefully and methodically. Regular maintenance and careful inspection of the wheels, tires, and axle components will ensure the grader runs efficiently and reliably. While the process requires some mechanical know-how, with the right tools and safety precautions, the job can be completed without major issues. Always remember that the health of your grader’s wheels directly impacts its performance in the field, so paying attention to this maintenance task is critical.

A failure to address worn-out tires or damaged axle components can lead to decreased machine performance or even operational breakdowns.
Key Considerations for Wheel Removal
Before diving into the process of wheel removal, it's important to consider a few basic factors:
- Proper Safety Protocols: Always prioritize safety by using the right equipment and tools. Hydraulic jacks, wheel chocks, and personal protective equipment (PPE) such as gloves and steel-toe boots are essential.
- Tools Needed: A hydraulic jack, axle stands, lug wrench or impact wrench, and a torque wrench are crucial for this task. These tools ensure that the wheels are removed and reinstalled safely and effectively.
- Tire Size and Compatibility: The Galion 118B motor grader uses specific wheel sizes that must be replaced with the same specifications. Ensure the replacement tires match the manufacturer’s guidelines for optimal performance.
- Position the Grader
Before starting, ensure that the grader is on stable, level ground. This will prevent tipping while removing the wheels. Engage the parking brake to keep the grader stationary.
- Lift the Rear of the Grader
Use a hydraulic jack to lift the rear of the grader. Once raised, position axle stands underneath the vehicle for added support. This ensures that the grader remains stable while you work on it.
- Loosen Lug Nuts
Using a lug wrench or an impact wrench, loosen the lug nuts that secure the rear wheels. It is recommended to do this while the vehicle is still on the ground to prevent the wheel from spinning. Loosen all nuts, but do not remove them completely yet.
- Remove the Wheel
After loosening the nuts, carefully remove them completely. Once all nuts are removed, gently pull the wheel off the hub. Depending on the condition of the wheel, it might require some effort to break it free from the hub. If there’s any resistance, gently tap the side of the wheel using a mallet (do not use excessive force to avoid damaging the wheel or axle).
- Inspect the Axle and Hub
After the wheel is removed, inspect the axle and hub for any visible signs of wear, damage, or corrosion. Pay special attention to the brake assembly, as this is another critical part that may need maintenance. Ensure that the axle is in good condition and that no oil or grease has leaked out. If necessary, clean the hub and surrounding areas before reinstalling the wheel.
- Replace the Wheel (If Needed)
If the goal of removing the wheel is to replace the tire, carefully place the new tire onto the hub. Make sure the alignment is correct and that the tire is seated properly. If you're using new tires, make sure they are of the correct size and type for the Galion 118B.
- Reinstall the Lug Nuts
With the new tire in place, reinstall the lug nuts and tighten them by hand. Once all nuts are back in place, use a torque wrench to tighten them to the manufacturer’s specified torque value. It’s important to tighten the nuts in a star pattern to ensure the even distribution of pressure on the wheel.
- Lower the Grader
After the wheel is secured, use the hydraulic jack to carefully lower the grader back to the ground. Once it is safely on the ground, use the torque wrench to ensure the lug nuts are properly torqued. Recheck them after a few hours of operation to ensure they have not loosened.
- Test the Equipment
Before heading back into the field, perform a test drive to ensure the grader is operating correctly. Check for any unusual vibrations, sounds, or issues related to the wheel installation. If any problems arise, it might be necessary to remove the wheel and check the components again.
- Wheel Not Seated Properly
If you notice any vibrations or irregular tire wear after reinstalling the wheel, it could mean the wheel is not seated properly. Recheck the alignment and ensure the wheel is securely mounted on the hub.
- Over-tightened or Under-tightened Lug Nuts
If the lug nuts are not properly torqued, it can cause wheel wobble, overheating of the brake system, or even damage to the axle. Always use a torque wrench to ensure accurate tightening.
- Worn Out Bearings or Axle Damage
During wheel removal, if you notice any unusual wear on the axle or bearings, it is a good idea to replace them immediately. Ignoring this can lead to further damage, affecting the stability and performance of the grader.
- Regular Inspections: Conduct frequent inspections of the wheel, axle, and hub. Checking these components for signs of wear can prevent unexpected failures.
- Proper Lubrication: Regularly lubricate the axles and bearings to reduce friction and wear. This will help extend the life of these components and ensure smoother operation.
- Tire Maintenance: Keep an eye on tire pressures and ensure they are properly inflated. Under-inflated tires can cause uneven wear and may result in poor traction, leading to potential breakdowns.
