6. FAQ

Q1: What is the difference between this item and a complete final drive?

A: This is travel motor head only (without reduction gearbox); complete final drive includes motor + planetary reduction gearbox integrated together. This motor is used for repairing existing gearbox assemblies.

Q2: Are 706-8J-01411 and 706-8J-01421 interchangeable?

A: Yes, they are superseded updated OEM part numbers for identical travel motor unit, fully interchangeable for replacement on all listed excavator models.

Q3: What is the difference between Rebuilt and Genuine New travel motor?

A: Rebuilt motor replaces all worn internal consumable parts (piston, valve plate, friction plates, oil seals), bench-calibrated to OEM performance standard with competitive price; Genuine New is original factory brand-new motor complying with full factory specification.
