Product Usage and Applicable Models
The Carrier Assembly, also known as the upper roller assembly or top roller assembly, plays a crucial role in the undercarriage system of a bulldozer. Its primary function is to support the weight of the track chain and prevent it from sagging between the front idler and the rear sprocket. This ensures smooth and efficient movement of the bulldozer, especially on uneven terrain.
This specific Carrier Assembly 113-15-42311 is precisely engineered for the following Komatsu bulldozer models:

Frequently Asked Questions
Q1: How often should I replace the carrier rollers on my bulldozer?A1: The lifespan of carrier rollers depends on various factors, including operating conditions and maintenance practices. Generally, inspect them regularly for wear and tear and replace them when you notice significant damage or decreased performance. Refer to your machine's manual for specific recommendations.
Q2: What are the signs of a failing carrier roller?A2: Common signs include unusual noises (squeaking or grinding), excessive vibration in the tracks, uneven track movement, and visible wear or damage to the roller or its seals.
Q3: Can I replace just one carrier roller, or should I replace them in pairs or as a set?A3: While you can replace a single damaged carrier roller, it's often recommended to replace them in pairs or as a set to ensure even wear and optimal performance of the undercarriage system. Consider the age and condition of the other rollers.
Troubleshooting and Maintenance Tips
Troubleshooting: If you notice uneven track movement or excessive noise, inspect the carrier rollers for damage, looseness, or lack of lubrication.
Maintenance Tip: Regularly lubricate the carrier rollers according to the manufacturer's recommendations. Keep the undercarriage clean from debris to prevent premature wear on all components, including the carrier assembly. Ensure proper track tension to avoid undue stress on the rollers.
