The Honda 23411-Z1C-000 Primary Drive Gear (22T) is a genuine OEM component designed for GX340 and GX390 horizontal shaft engines. As a direct Honda OEM replacement, this gear is manufactured to the same specifications as the original, ensuring correct tooth count and mesh characteristics for the drivetrain. Buyers should verify their engine serial number against the fitment table, as Honda introduces part supersessions at serial breaks — the 22-tooth variant is the key identifier that determines whether this is the correct gear for your unit.
Key Features
- Correct Tooth Profile — a 22-tooth primary drive gear must mesh precisely with its mating components; this genuine OEM part delivers the tooth geometry Honda engineered for the GX340 and GX390 drivetrain
- Genuine Honda OEM — sourced directly from Honda, manufactured to the same standards as the part that came in your engine, with no guesswork on dimensions or fit
- Confirmed Fitment — designed specifically for GX340 and GX390 horizontal shaft engines; check your serial number against the fitment table to confirm this is the right gear for your serial range
- Drivetrain Integrity — a worn or damaged primary drive gear causes slipping, noise, and loss of power transfer; replacing it with the correct OEM part restores smooth, consistent power delivery to the driven load
The primary drive gear is a core component of the engine's power transmission system. When this gear wears or its teeth become damaged, the result is rough engagement, audible gear noise, or a complete loss of power transmission; fitting the correct 22-tooth OEM replacement restores the engagement the engine was designed to deliver.
