Used, inspected Taylor-Dunn industrial vehicle parts are carried by Sun Coast Cycle Sports at our Odessa, Florida salvage facility. Components are removed from donor units, photographed individually, assigned dedicated SKUs, and shipped free throughout the lower 48 states. Taylor-Dunn manufactures electric and gas-powered burden carriers, personnel carriers, stockchasers, and tow tractors used in warehouses, manufacturing plants, airports, military bases, and large commercial facilities. These are not recreational vehicles but rather industrial-grade machines designed for constant low-speed operation in commercial environments. Because Taylor-Dunn vehicles often remain in service for decades, replacement parts for older models can be difficult to source through OEM channels, and salvage components provide a cost-effective alternative.
Taylor-Dunn model overview
Taylor-Dunn was founded in 1949 in Anaheim, California, and remains one of the oldest continuously operating electric vehicle manufacturers in the United States. The company was acquired by Polaris Industries in 2016, placing it under the same corporate umbrella as GEM (Global Electric Motorcars) and Polaris commercial vehicles. Taylor-Dunn's core product lines include the B-Series burden carriers (flatbed and stake-side utility vehicles), the R-Series personnel carriers (shuttle vehicles), the SC-Series stockchasers (compact warehouse vehicles for order picking), and the GT-Series tow tractors (designed for towing trailers in industrial and airport environments).
Taylor-Dunn vehicles are built for longevity. Many facilities operate B-Series burden carriers for 20-30 years with periodic motor, controller, and battery replacements. The company uses standardized electric drive systems across multiple platforms: 36V, 48V, or 72V battery configurations with GE, AMD, or Sepex motors and Curtis controllers. Gas-powered models use Kohler or similar industrial engines. For parts sourcing, the key compatibility factor is the drive system voltage and motor type rather than the vehicle model name, as Taylor-Dunn has used similar drivetrain architectures across multiple product lines over the decades.
Models and year compatibility guide
| Model | Configuration | Drivetrain | Platform notes |
|---|
| B-Series (B0, B2-48, B-248, etc.) | Burden carrier / flatbed utility | 36V, 48V, or 72V electric; or gas (Kohler) | Taylor-Dunn's core product. Multiple configurations with varying bed sizes and payload ratings. Electric models use Curtis controllers and GE or AMD motors. The B-Series has been in production for decades with incremental updates, and many older components remain dimensionally compatible with newer production runs. |
| R-Series (R3-80, R-380, etc.) | Personnel carrier / shuttle | 48V or 72V electric | Multi-passenger shuttle vehicles (3-row and 4-row seating configurations). Shares drivetrain components (motors, controllers, chargers) with B-Series vehicles of the same voltage. Frame and body are R-Series-specific. |
| SC-Series (SC-100, SC-175, etc.) | Stockchaser / order picker | 24V or 36V electric | Compact warehouse vehicles designed for indoor use on smooth floors. Lower voltage systems than the B and R Series. Standing or sit-down operator position depending on model. Small footprint for navigating warehouse aisles. |
| GT-Series (GT-320, GT-371, etc.) | Tow tractor | 36V or 48V electric; or gas | Designed for towing trailer trains in airports, manufacturing plants, and distribution centers. Heavy-duty axles and tow hitches. Drivetrain components (motor, controller) may interchange with B-Series of the same voltage and motor type. |
| Bigfoot | Heavy-duty burden carrier | 48V or gas | Higher payload capacity than standard B-Series. Reinforced frame and suspension. Upgraded brake system. Some drivetrain components shared with the standard B-Series. |
Common failure points and frequently replaced components
Electric drive systems (all models): Battery pack degradation is the most common and expensive maintenance item on Taylor-Dunn electric vehicles. Lead-acid battery packs (the standard on most models) typically last 3-5 years in heavy commercial use with proper watering and equalization charging. Neglected batteries (low water levels, sulfation from undercharging) fail sooner. Curtis controllers can develop fault codes related to thermal overload, particularly in hot environments or during sustained uphill operation. Motor brush wear requires periodic inspection and replacement, typically every 1-3 years depending on duty cycle. Solenoid failures cause no-start or no-drive conditions and are a frequent diagnostic starting point.
Mechanical systems: Steering components (tie rod ends, king pins, steering boxes) wear under the constant low-speed turning typical of warehouse and campus use. Brake shoes and drums require regular adjustment and periodic replacement. Rear axle bearings and seals can leak or fail on high-mileage units. Leaf springs and suspension bushings deteriorate on vehicles used outdoors on rough surfaces. Charger failures (both onboard and external) are common on older units, often caused by corroded AC input connections or capacitor degradation inside the charger housing.
Gas models: Kohler engine carburetor issues (particularly in vehicles stored for extended periods), ignition coil failures, and exhaust system corrosion are the primary gas-specific concerns. Fuel system components degrade when vehicles sit idle with ethanol-blended fuel.

Frequently asked questions
Q: Are Taylor-Dunn parts compatible with Polaris GEM vehicles?
While both brands are owned by Polaris, Taylor-Dunn and GEM vehicles are completely different platforms with separate engineering origins. Drivetrain components, controllers, motors, and frames are not interchangeable between them. Parts must be sourced specifically for the Taylor-Dunn model you own.
Q: Can I upgrade a 36V Taylor-Dunn to 48V?
Voltage conversions require replacing the entire electrical drivetrain: motor, controller, charger, wiring harness, and battery pack. It is not a simple battery swap. Sourcing a complete 48V drivetrain from a 48V donor vehicle is the most practical approach for this type of upgrade, as the components are designed to work together.
Q: Why are OEM Taylor-Dunn parts expensive?
Taylor-Dunn vehicles are commercial/industrial equipment with relatively low production volumes compared to consumer golf carts. OEM parts are priced for the commercial market where vehicles are fleet-maintained with allocated budgets. Salvage parts from decommissioned units provide a cost-effective alternative, particularly for older models where OEM availability has become limited.
Q: How do I identify my Taylor-Dunn model and serial number?
The serial number plate is typically located on the left (driver) side of the frame, near the dashboard or under the seat. The serial number encodes the model designation, production sequence, and year. Taylor-Dunn's customer service department can decode the serial number to identify exact specifications, drivetrain voltage, and original equipment.
