HITY MOTOR Starter & Relay Solenoid for Yamaha ATV — 12V PMDD 9‑Tooth CCW, Fits Warrior/Moto‑4/Kodiak/Terra Pro/Big Bear

Hity Motor Starter & Relay Solenoid is a direct-fit 12V PMDD starter and matching relay designed to replace worn units on many Yamaha ATV models from the late 1980s through the 1990s.

This kit pairs a 12-volt, PMDD-type starter motor (9 teeth, CCW rotation) with a matching relay solenoid to restore reliable engine cranking for a range of Yamaha four-wheelers. Built to match common OEM dimensions and electrical characteristics, the assembly fits a variety of models including Kodiak, Moto-4, Terra Pro, Warrior and Big Bear machines. The package ships with both the starter motor and the relay solenoid so you can replace the drive and switching components together.

Which Yamaha ATVs will this starter and solenoid work with?

This Hity Motor assembly is engineered to fit specific Yamaha model years where the PMDD-type starter and relay were used. Confirm compatibility by matching model and year, and checking that your machine uses a 9-tooth, CCW rotation starter.

• Kodiak 400 YFM400 (1993–1998)
• Moto-4 350 YFM350 (1987–1995)
• Terra Pro 350 YFP350U (1988)
• Warrior 350 YFM350 (1987–2004)
• Big Bear 350 YFM350U 2x4 (1996–1999)

How does this starter unit match original equipment specifications?

The starter motor uses a permanent magnet direct-drive (PMDD) design with nine teeth and counterclockwise rotation to mirror the OEM units used on these Yamaha ATVs. It is a 12V starter built to engage factory flywheels and meshes with standard starter drives and mounting points.

• Starter type: PMDD (permanent magnet direct drive)
• Voltage: 12V, suitable for stock electrical systems
• Rotation: CCW (counterclockwise) and 9-tooth pinion
• Includes relay solenoid engineered for compatible electrical switching

What steps should I take before installing this replacement?

Before installing, compare part dimensions, mounting bolt pattern and electrical connectors to the unit removed from your ATV. Disconnect the battery, label any wiring, and verify tooth count and rotation; incorrect matches can prevent proper engagement or cause damage.

• Confirm OEM part numbers or compare physical dimensions
• Disconnect battery and safely remove the old starter and solenoid
• Ensure wiring connectors and bolt locations match the replacement
• Test wiring and battery voltage before final reassembly

Can this starter replace multiple OEM part numbers?

Yes — the Hity Motor assembly is intended as a replacement for a range of OEM references commonly found on the listed Yamaha models. Check your old part number or consult a parts diagram to confirm exact interchangeability.

• Compatible with many OEM numbers often listed for these ATVs
• Supplied as a starter motor plus relay solenoid for a complete swap
• Ideal when both the drive motor and switching relay show wear

Who is this for: This product is aimed at ATV owners, independent mechanics and restoration projects needing a reliable, cost-effective replacement starter and relay for older Yamaha four-wheelers. If you own one of the listed models and your stock starter shows slow cranking, clicking, or electrical faults, this kit provides a direct-fit option to get your machine turning over again. Always verify fit with your machine’s model year and part details before purchasing.
