The travel motor is the heart of an excavator final drive — it converts hydraulic flow into the torque that moves the tracks. Most final drives are built around proven travel motor platforms, and knowing which brand you have makes sourcing replacement parts far easier.
This guide covers the travel motor brands most commonly found in excavator final drives — KYB, Nabtesco, NACHI, and Rexroth — and where to source aftermarket replacements.
KYB (Kayaba) is one of the world's largest hydraulic component makers and a major supplier of travel motors for excavators, particularly Japanese and Korean brands. KYB travel motors are common in mini and mid-size machines. BN Gears stocks aftermarket KYB travel motors and components.
Nabtesco (formerly Teijin Seiki) supplies travel motors widely used across Japanese excavator brands and many others worldwide. Nabtesco units are known for reliability in high-cycle applications. BN Gears stocks aftermarket Nabtesco travel motors and components.

Bosch Rexroth is the leading European hydraulic supplier; its GFT and MCR series travel motors and gearboxes are found in many European and Chinese-brand excavators. BN Gears stocks aftermarket Rexroth travel motors and components.

Find the brand name cast or stamped on the motor housing
Record the model/part number (e.g., KPM, GFT, MCR series designations)
Check the number of ports and the port thread sizes
Note whether you need the motor alone or a complete final drive assembly
If the gearbox section is healthy, replacing only the travel motor is the economical route. If the planetary gears, bearings, or seals are also worn — noise, leaks, and weak travel together — a complete final drive assembly is the better investment.
