This replacement unit fits a range of classic Yamaha four-wheelers and is built to the same basic form factor as many OEM starters. It has a permanent magnet direct drive (PMDD) design with counterclockwise rotation and a 9-tooth pinion, and it ships with both the starter motor and the relay solenoid to simplify installation. The listing lists specific year and model compatibility so you can confirm fit before purchase.

Which Yamaha models does this starter fit?

The Hity Motor starter is made to match fitment for several Yamaha ATV models across late 1980s and 1990s production years. Confirm your model and year against the compatibility list to ensure correct fitment, and compare the pinion teeth count and rotation if you are unsure.

What are the technical specifications I need to check?

This unit is specified as a PMDD (permanent magnet direct drive) starter running on 12 volts, with counterclockwise (CCW) rotation and a 9-tooth drive pinion. Those three details—type, voltage and rotation—are the primary mechanical/electrical checks to confirm compatibility with your ATV’s starter ring gear and electrical system.

• Starter unit type: PMDD (permanent magnet direct drive)
• Operating voltage: 12 V
• Rotation direction: Counterclockwise (CCW)
• Pinion teeth: 9

Does it replace OEM part numbers I might have?

Yes — this Hity Motor assembly is listed as a replacement for a variety of OEM part numbers commonly referenced for these Yamaha ATVs. If you have an OEM number, cross-check it with the listed references or compare physical dimensions and electrical connections to be certain of interchangeability.

• Replaces OEM numbers such as 31464-C17-24, 128000-3760, 128000-4240 and many others
• Delivered as a paired starter motor and relay solenoid for an easier swap
• Compare pinion tooth count and rotation when verifying replacement suitability

What comes in the package and what should I prepare for installation?

The package includes one starter motor and one relay solenoid — enough to replace both components in a single service. You should have basic hand tools, a battery with sufficient charge, and a secure working area; follow safe battery-disconnection practices before removing the old starter and solenoid.

• Package contents: 1 starter motor + 1 relay solenoid
• Recommended preparation: disconnect battery and access starter mounting bolts
• Check wiring connections and secure all connectors after installation

Who is this for: This Hity Motor starter and relay solenoid kit is intended for owners, mechanics, or restoration enthusiasts working on compatible Yamaha ATVs from the late 1980s through the 1990s who need a direct-replacement starter assembly. It suits those who prefer receiving both the starter and the relay solenoid together for a straightforward swap and who will verify CCW rotation, 12V supply, and 9-tooth pinion fit before installation.
