The Caterpillar 375 is a large excavator, and its track rollers are crucial for smooth operation and longevity of the undercarriage. Here’s what you need to know about Cat 375 track rollers:

Cat 375 Track Roller Specifications:

• Type: Bottom rollers (load-carrying)

• Quantity: Typically 7–9 per side (varies by configuration)

• Material: Hardened steel with sealed bearings

• Lubrication: Grease-filled or oil-bath (depends on model)

• Compatibility: Must match OEM or high-quality aftermarket specs

Common Part Numbers (Check Serial Number for Exact Match):

• OEM Cat Part Numbers:

  • Standard Roller: 6y1824 (older models)

  • Updated Roller: CR6378 (newer versions)

  • Sealed Roller Assembly: 395-6116 (varies by SN)

• Aftermarket Alternatives: CQC, DPW,  and others offer compatible rollers.

Signs of a Failing Track Roller on a Cat 375:

• Uneven track wear or excessive sag

• Grinding noises from the undercarriage

• Leaking grease (damaged seals)

• Flat spots or cracks on the roller surface

Replacement Tips:

1. Check Serial Number – Verify exact roller specs using the machine’s S/N on the Cat Parts Catalog.

2. Inspect Adjacent Components – Replace worn sprockets, idlers, or bushings at the same time if needed.

3. Torque Properly – Follow Cat’s bolt tightening specs to avoid undercarriage misalignment.

4. Consider Aftermarket – High-quality aftermarket rollers (like Berco) can be cost-effective if OEM is too expensive.
