Premium Final Drive Assemblies for Heavy Equipment
Whether you operate excavators, loaders, tractors, or skid-steers, the final drive assembly is one of the most critical components of your machine's undercarriage system. At Fab Heavy Parts, we supply engineering-grade final drive motors and travel motors designed for reliable performance, precise fitment, and extended service life.
What is a Final Drive Assembly?
A final drive assembly (also called a travel motor or travel drive) is the hydraulic motor and gearbox system that converts hydraulic power into rotational force to drive your machine's tracks or wheels. Key components include:
- Hydraulic Motor: Converts hydraulic pressure into mechanical rotation
- Planetary Gearbox: Reduces speed and multiplies torque for optimal track or wheel drive
- Carrier Assembly: Houses the planetary gears and bearings
- Seals & Bearings: Protect internal components from contamination and ensure smooth operation
- Output Shaft: Transfers power to the sprocket or wheel hub
Final drives are subject to extreme loads, contamination, and wear. Selecting the correct assembly and maintaining it properly is essential for machine uptime and operational efficiency.
How to Order the Correct Final Drive Assembly
Ordering the right final drive requires precise fitment validation. Follow these steps to ensure compatibility:
- Identify Your Machine: Note the make, model, and serial number of your equipment (e.g., Caterpillar 320D, Kubota KX080, Bobcat S650)
- Check OEM Part Numbers: Reference your machine's parts manual or existing final drive for the manufacturer part number
- Verify Specifications: Confirm mounting bolt patterns, shaft dimensions, displacement (cc/rev), and gear ratios
- Cross-Reference: Use our product listings to match OEM numbers with our premium aftermarket assemblies
- Request Technical Support: If you're unsure about fitment, our team can validate compatibility using your machine data
