Description

The Bobcat 328G Final Drive is a complete hydraulic travel motor and reduction gearbox assembly designed to deliver reliable track movement for compatible Bobcat 328G mini excavators. The final drive is a critical component of the excavator’s travel system, converting hydraulic power from the machine into controlled movement through the tracks.

When a final drive becomes worn or damaged, operators may experience reduced travel performance, weak tracking power, uneven movement or difficulty steering. Replacing the affected unit with a correctly matched Bobcat final drive can help restore smooth operation, improve machine control and reduce unnecessary downtime.

The Bobcat 328G is commonly used in construction, landscaping, earthmoving, trenching, utility work and general excavation applications where compact size and precise movement are essential. A reliable excavator travel motor helps ensure the machine can move confidently across uneven surfaces, confined areas and demanding job sites.

Designed for Compact Excavator Performance

The Bobcat 328G Final Drive combines a hydraulic motor and planetary reduction gearbox to provide the torque required to move the excavator tracks. The internal components are designed to handle the constant loads generated during travelling, turning and positioning operations.

A properly functioning final drive supports:

• Smooth forward and reverse travel
• Improved tracking control
• Consistent pushing and grading performance
• Better manoeuvrability on uneven terrain
• Reduced stress on other travel system components

Common signs that your Bobcat 328G final drive may require replacement include:

• One track moving slower than the other
• Reduced travel strength when climbing or pushing
• Grinding, knocking or unusual operating noises
• Hydraulic oil leaks around the drive unit
• Track movement stopping under load
• Excessive vibration during operation
• Poor steering response while travelling

These symptoms may also be caused by hydraulic system issues, undercarriage wear or control valve problems. A complete inspection is recommended before replacing the final drive.

Correct Fitment Confirmation

Bobcat excavators can have different configurations depending on manufacturing year, machine specifications and original equipment setup. Final drive compatibility may vary according to mounting design, hydraulic connections, motor configuration and operating requirements.

To ensure the correct replacement unit is supplied, provide:

• Excavator model details
• Machine serial number
• Photos of the existing final drive
• Hydraulic connection images
• Mounting and sprocket details if required

Arena Hydraulic and Machinery can review your machine information and assist with identifying the correct replacement Bobcat 328G Final Drive for your excavator.

Reliable Travel Power and Machine Control

A quality Bobcat 328G Final Drive helps maintain efficient hydraulic power transfer between the excavator and tracks. This allows operators to perform digging, trenching, loading, grading and positioning tasks with improved control and confidence.

A worn travel motor can affect productivity by reducing movement speed and making the excavator harder to operate. Installing a suitable replacement final drive helps return the machine closer to its expected operating performance while reducing interruptions on site.

Aftermarket and Reconditioned Final Drive Options

Arena Hydraulic and Machinery supplies quality aftermarket hydraulic solutions for excavators, including replacement and reconditioned final drive options where available.

Each available unit is selected to provide dependable performance and value for businesses looking to repair or maintain their Bobcat machinery without unnecessary equipment downtime.

Whether replacing a failed travel motor or preparing your excavator for continued operation, the correct final drive solution can help extend machine service life and improve overall efficiency.

Installation and Maintenance Advice

Professional installation is recommended when replacing a Bobcat 328G Final Drive. Before fitting a replacement unit, the hydraulic system should be inspected to identify possible causes of failure, including contamination, damaged hoses, incorrect oil levels or excessive undercarriage wear.

To maximise final drive service life:

• Maintain clean hydraulic oil
• Check gearbox oil levels regularly
• Inspect hydraulic hoses and fittings
• Maintain correct track tension
• Remove dirt and debris from the undercarriage
• Address unusual noises or performance changes early

Regular maintenance helps protect the travel motor and supports reliable excavator operation.
