Briggs & Stratton Governor Gear 793338 OEM replacement for 401000/405000/406000 engines, restores stable RPM

If your Briggs & Stratton engine is showing irregular throttle behavior, hunting, or inconsistent RPM, the governor gear can be a common wear item. The 793338 governor gear is a factory-made component that replaces old part numbers 698231, 696376, and 394348 and installs directly into many 401000, 405000, and 406000 series engines. Choosing a genuine Briggs & Stratton part helps maintain original tolerances and long-term compatibility.

How will this governor gear affect engine performance?

Replacing a worn governor gear restores the mechanical link that controls engine speed under load. That helps stabilize RPMs, reduces throttle hunting, and protects the engine from overspeed conditions when the throttle linkage is engaged.

• Restores correct governor-to-throttle engagement for steady RPM
• Reduces engine hunting and erratic speed changes under load
• Helps maintain safe maximum engine speed by improving control

Which Briggs & Stratton models and old parts does 793338 fit?

This is an OEM part made to fit many small Briggs & Stratton models, especially from the 401000, 405000, and 406000 engine families. It replaces previous Briggs part numbers 698231, 696376, and 394348, so you can use those legacy numbers to confirm compatibility.

• Direct replacement for Briggs #698231, #696376, and #394348
• Commonly used in 401000, 405000, and 406000 model engines

What should I know before installing this governor gear?

Installation requires basic engine disassembly around the governor assembly and careful reassembly to maintain alignment and clearances. Use the factory service manual or follow torque and timing procedures; improper installation can affect governor response or throttle linkage operation.

• Inspect mating parts (shafts, linkage) for wear before install
• Follow Briggs & Stratton torque specs and timing recommendations
• Replace related fasteners or clips if damaged during removal

How durable is this replacement and what materials are used?
