For small excavators to maintain long-term stable operation of their track systems, key components must not be overlooked! Today, we recommend this 146-6064 top roller – a high-spec aftermarket replacement part designed to solve track support challenges. With excellent compatibility and durability, it ensures your equipment operates with greater peace of mind.
✅ Full Coverage of Compatible Models, Precise Fit:
Not only does it perfectly fit popular models like Caterpillar 302.5, 302.5C, and 303.5, but it also works with Mitsubishi MM35. Special note: All models with serial numbers 4AZ1 and above can be used with confidence, no need to worry about compatibility issues.
✨ Reasonable Structural Design, Uncompromised Core Function:
Each machine is equipped with one roller on each side, installed in the central position at the top of the undercarriage – like adding a “stable bracket” to the track. It firmly supports the track, effectively preventing it from sagging due to gravity or collapsing into the track frame. This reduces friction and wear between the track and other components, fundamentally lowering the risk of failures and extending the equipment’s service life.
�� Alternate Part Number Matches the Original: 146-6064, consistent with Caterpillar dealer part numbers. No extra verification is needed during replacement, making the process hassle-free and efficient.
�� Friendly Reminder: Although the compatibility range is clear, specific conditions of each machine may vary. Please recheck your equipment’s model and serial number before placing an order to ensure everything goes smoothly!
Whether for daily maintenance or component replacement, the 146-6064 top roller is an ideal choice for models like the CAT302.5. With solid quality and easy installation, it keeps your small excavator in optimal working condition, effortlessly handling various operating environments!
