The Multiquip 1668355320 Governor Gear is a genuine OEM component designed for KD1800, KD1800KD6, and KD6 series core drills. As a direct factory replacement, this gear delivers the exact tooth profile and dimensional tolerances required to keep the governor system operating as intended. Sourced directly from Multiquip, part 1668355320 ensures you are installing the same component the machine was built with. If your core drill is surging, hunting, or failing to hold a steady speed under load, a worn or damaged governor gear is a common culprit worth inspecting first.
Key Features
- OEM Gear Precision — Manufactured to the exact tooth count and profile spec required for correct governor engagement, not a generalized approximation.
- Direct Drop-In Replacement — Matches the original mounting configuration and gear interface on KD1800 and KD6 core drills for a straightforward swap during service.
- Confirmed Fitment — Verified for KD1800, KD1800KD6, and KD6 Multiquip core drill models.
- Steady Engine Speed Under Load — A correctly functioning governor gear allows the engine to maintain consistent RPM as drilling resistance changes, protecting both the engine and the core bit.
- Genuine Multiquip OEM Part — Backed by Multiquip's manufacturing standards, giving you confidence that the replacement will perform and wear at the same rate as the original component.
The governor gear is a critical link in the engine's speed-regulation system. It transfers rotational input from the engine to the governor mechanism, which responds to changes in load by adjusting the throttle to maintain a set RPM. When this gear wears, chips, or loses tooth engagement, the governor loses its ability to react accurately — causing the engine to surge, lug, or over-rev depending on conditions. Replacing a damaged governor gear restores the closed-loop speed control the engine relies on for consistent, controlled drilling performance.
