096-4319-0964319 Sun Gear 096 4319 — Cat 3116 E200B

This is a precision-engineered sun gear, a critical component within the planetary gear set of a transmission or final drive system. It is manufactured from hardened steel to withstand high torque loads and resist wear, ensuring smooth power transfer, unlike a worn gear with chipped or rounded teeth. Operator-observed symptoms of a failing sun gear include grinding noises during operation, difficulty shifting gears, or a noticeable loss of drive power.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

Early signs of sun gear wear may manifest as a whining or grinding noise that changes with vehicle speed or load. If ignored, the gear teeth can further degrade, leading to rough shifting, loss of drive, or complete transmission failure. A severely damaged sun gear can cause catastrophic internal damage to the entire gear set.

Installation Tip

Ensure all bearing surfaces that support the sun gear are thoroughly cleaned and lubricated before installation. Proper alignment is critical; avoid forcing the gear into place, as this can damage the gear teeth or housing.

Service Note

When replacing a sun gear, always inspect and replace worn bearings, seals, and the lubricant within the transmission or final drive.
