OLIFANT Starter Motor for Honda FourTrax TRX300 TRX300FW (1988–2000) — 12V PMDD, CCW 10-Spline High-Torque

Compact 12V replacement starter motor engineered to restore reliable cranking for Honda FourTrax/TRX300 and compatible 1987–2000 off-road models.

This OLIFANT starter motor is a direct-fit, high-torque PMDD unit designed for Honda FourTrax 300 models (TRX300, TRX300FW) from 1988 through 2000, plus compatibility with certain 1987 ATC/TRX 246cc models. Built with reinforced internal components and a reduction-gear drive, it provides steady cranking performance while minimizing battery draw. The unit matches OEM mounting and electrical interfaces and lists multiple part numbers for cross-reference to simplify selection and fitment.

How does this starter improve cold or slow cranking?

The OLIFANT starter uses a permanent magnet direct drive (PMDD) design with robust internal motor windings and reduction gearing to deliver consistent torque without excessive current demand. That steadier torque profile helps the engine spin over more reliably under low-temperature or low-charge conditions. It’s engineered to balance power and efficiency so your battery isn’t taxed by repeated attempts.

• 12V system compatibility for common Honda ATVs
• Reduction gears increase output torque while reducing stall current
• Durable internal motor construction for longer service life
• CCW rotation and 10-tooth, 10-spline drive shaft to match OEM

Will this starter fit my Honda model and which part numbers does it replace?

This unit is made to fit Honda FourTrax 300 TRX300 and TRX300FW models from 1988 to 2000 and is also compatible with select 1987 246cc machines such as TRX250, ATC250SX, and ATC250ES. It replaces multiple OEM references, making it easy to verify compatibility with your current part number. Always check mounting holes, electrical connectors, and shaft specifications before installation.

• Compatible models: FourTrax/TRX300 (1988–2000), TRX250/ATC250SX/ATC250ES (1987)
• OEM cross-reference: 31200-HA0-773, 31200-HA0-774
• Additional part numbers: 31200-HC4-003, 31200-HC4-013, 31200-HC4-023
• Confirm CCW rotation and 10-spline, 10-tooth shaft for proper fit

What are the electrical and mechanical specifications I should know?

The starter is specified for a 12-volt electrical system and is built with a counterclockwise (CCW) rotation output. It includes a 10-tooth pinion on a 10-spline shaft to mesh with OEM ring gear teeth. The PMDD starter type provides reliable torque delivery while drawing less current compared with some older designs.

• Voltage: 12V to match typical ATV electrical systems
• Rotation: CCW (counterclockwise)
• Drive: 10 teeth on a 10-spline shaft for OEM compatibility
• Starter type: PMDD with reduction gearing for improved torque

How difficult is installation and what should I check before ordering?

Installation is similar to most motorcycle/ATV starter replacements and typically requires basic hand tools, safe battery disconnection, and access to the starter mounting area. Verify the starter mounting flange, electrical terminal type, and pinion dimensions against your existing unit to ensure a direct replacement. If you’re not confident working on the starter circuit, a professional mechanic can complete the swap quickly.

• Disconnect battery negative before removal
• Compare mounting pattern and electrical connectors to your old starter
• Use appropriate torque on mounting bolts to prevent leaks or misalignment
• Test cranking after installation and before full reassembly

Who is this for: Riders and mechanics who need a dependable, OEM-compatible starter replacement for late‑80s to late‑90s Honda FourTrax/TRX300 machines or for compatible 1987 ATC/TRX 246cc models. It’s aimed at owners who want a high-quality PMDD starter that balances strong cranking performance with controlled current draw and straightforward bolt-on fitment.
