Why Choose This Coupling Flange

The coupling flange is a critical component of your Caterpillar machine’s driveline system — it securely joins rotating driveline shafts and transfers full engine torque to the axles, tracks, or working attachments under demanding load cycles. A worn or damaged coupling flange causes driveline vibration, power loss, excessive noise, and potential driveshaft failure, leading to costly downtime and unsafe machine operation. This replacement unit delivers:

• Precise torque transfer – Engineered to maintain correct driveline alignment and coupling integrity for Caterpillar TH210, TH215, 933C, 939C, 914G2, M313C, and CP11 powertrain systems
• Exact-fit installation – Direct replacement with correct bolt pattern, spline specification, and flange diameter
• Durable construction – Built to withstand the high-torque demands and continuous duty cycles of heavy construction and compaction equipment operation
• Cost-effective solution – Aftermarket quality at a fraction of dealer pricing
