The Komatsu D135A-2 is a powerful and durable crawler dozer commonly used in construction and mining operations. Known for its robust performance, the D135A-2 is equipped with high-quality components designed for heavy-duty work. However, like any piece of machinery, parts can wear out over time, particularly components that are under continuous strain, such as the sprockets. In this article, we will explore the process of finding and replacing sprockets for the Komatsu D135A-2, as well as provide insights on how to maintain this vital component for optimal machine performance.
Understanding the Role of Sprockets in the Komatsu D135A-2
Sprockets are integral to the movement of tracked machines like the Komatsu D135A-2. These toothed wheels engage with the track's metal links, enabling the dozer to move efficiently across rugged terrain. The sprockets undergo substantial wear and tear due to the constant friction, pressure, and movement involved in the machine's operation. Over time, they can become worn, leading to reduced efficiency, misalignment, or even complete failure if not replaced.
Given their importance in the machine’s drivetrain, timely sprocket replacement is essential for maintaining the machine's optimal performance and avoiding unnecessary downtime.
Signs that Sprockets Need Replacement
Before diving into where to find sprockets, it’s essential to understand how to identify when they need to be replaced. Here are common signs that your Komatsu D135A-2’s sprockets might be worn or damaged:
Once you’ve identified the need for sprocket replacement, the next step is finding the correct replacement parts. There are several options available for sourcing sprockets for the Komatsu D135A-2:
1. Komatsu Dealerships and Authorized Dealers
One of the most reliable ways to find genuine sprockets for the Komatsu D135A-2 is through an authorized Komatsu dealership or dealer network. These dealerships typically carry OEM (Original Equipment Manufacturer) parts, ensuring that the sprockets will match the specifications and performance standards set by Komatsu.
If you're looking for a more budget-friendly option, aftermarket suppliers offer sprockets that are designed to fit the Komatsu D135A-2. These parts are made by third-party manufacturers and are often priced lower than OEM parts. While aftermarket parts can be a good option, it’s important to ensure that they meet the necessary quality standards.
Some popular aftermarket suppliers include:
For cost-conscious buyers, purchasing used or refurbished sprockets can be a viable option. Many heavy equipment salvage yards specialize in selling used parts, including sprockets, at a fraction of the cost of new parts. While used parts can offer substantial savings, it's essential to inspect them thoroughly for wear, cracks, or other signs of damage.
Websites like eBay, Amazon, and Alibaba often have listings for sprockets for the Komatsu D135A-2. These platforms can connect you with both OEM and aftermarket suppliers. However, purchasing through these channels comes with the risk of receiving counterfeit or low-quality parts, so it's essential to read reviews and confirm the seller’s reputation.
Replacing the sprockets on your Komatsu D135A-2 is a moderately involved process that requires specific tools and mechanical expertise. Below are the general steps involved in the sprocket replacement procedure:
1. Prepare the Equipment and Workspace
Before starting, ensure the machine is on a flat, stable surface. Use jack stands or other proper supports to lift the dozer and relieve tension on the tracks.
2. Remove the Track
To replace the sprockets, the track must first be removed. This typically involves loosening the track tension and detaching the track from the sprockets. Using a track puller tool can make this step easier.
3. Remove the Old Sprockets
Once the track is removed, use appropriate wrenches and tools to detach the old sprockets from the track drive assembly. Take note of the way the sprockets are attached, as you will need to reassemble the new ones in the same configuration.
4. Install the New Sprockets
Position the new sprockets onto the track drive assembly, ensuring they fit properly into place. Secure the sprockets by tightening the bolts or fasteners. Make sure the sprockets are aligned correctly to avoid any issues with the track movement.
5. Reinstall the Track
Once the new sprockets are in place, reinstall the track, ensuring it is properly aligned with the sprockets. Adjust the track tension to the manufacturer’s specifications.
6. Test the Dozer
Before putting the Komatsu D135A-2 back into full service, perform a test run to ensure that the tracks are engaging correctly with the sprockets and that the machine is operating smoothly without issues.
Conclusion
Replacing sprockets on the Komatsu D135A-2 is an essential maintenance task that can prevent further damage to the undercarriage and maintain the machine’s efficiency. By carefully monitoring for signs of wear and seeking out the right replacement parts, you can ensure that your dozer continues to perform at its best.
When searching for new or replacement sprockets, you can choose from various sources, including authorized dealerships, aftermarket suppliers, salvage yards, and online platforms. While cost is an important consideration, it's also crucial to prioritize quality and compatibility to avoid costly repairs in the future.
As with any major repair, following the correct procedure and using the right tools will ensure the smooth and efficient operation of your Komatsu D135A-2 for years to come.

Signs that Sprockets Need Replacement
Before diving into where to find sprockets, it’s essential to understand how to identify when they need to be replaced. Here are common signs that your Komatsu D135A-2’s sprockets might be worn or damaged:
- Visible Wear on Teeth: The teeth of the sprockets can become rounded or chipped after extended use, reducing their ability to engage properly with the track links. If the teeth look worn down, it’s time for a replacement.
- Track Slippage: If you notice the track slipping or the dozer having difficulty moving under load, this could indicate that the sprockets are not making proper contact with the track, requiring replacement.
- Uneven Track Wear: Uneven wear on the track links, such as one side being more worn than the other, can be a sign of sprocket misalignment or damage.
- Noisy Operation: Excessive noise while operating the machine, especially when the tracks are engaged, can indicate worn sprockets that need attention.
