Briggs Stratton 790842 Air Cleaner Knob

Product Description

The BRIGGS STRATTON 790842 is a replacement air cleaner knob designed for use on small gasoline engines. This knob secures the air cleaner assembly to the carburetor or air cleaner housing, keeping the filter element properly seated during operation. A secure air cleaner connection is critical for preventing unfiltered air from entering the engine, which can accelerate internal wear. This is an OEM-specification replacement part intended for installation by small engine technicians or experienced equipment service professionals familiar with Briggs and Stratton engine maintenance procedures.

This air cleaner knob is used on walk-behind lawn mowers, riding tractors, and other outdoor power equipment powered by Briggs and Stratton engines. It is a common service item replaced during routine air filter maintenance or after the original knob becomes damaged, stripped, or lost. Compatible equipment is found in both residential and light commercial lawn and garden applications.

Key Features

• OEM replacement part for the original air cleaner knob
• Secures the air cleaner housing or filter cover to prevent unfiltered air ingestion
• Direct-fit design for straightforward service without modification
• Suitable for use on Briggs and Stratton small engine platforms used in lawn and garden equipment

Compatibility

Designed as an OEM-style replacement air cleaner knob for Briggs and Stratton small engines used in lawn and garden power equipment. Refer to your equipment's parts manual or the Briggs and Stratton parts lookup tool using the engine model and code numbers to confirm fitment before installation.

Installation Notes

Installation should be performed by a qualified small engine technician or a knowledgeable equipment owner. Before servicing the air cleaner assembly, disconnect the spark plug wire to prevent accidental engine start. Thread the knob by hand to avoid cross-threading, and tighten only to snug — do not overtighten, as the housing threads can strip. Ensure the air filter element is properly seated before reinstalling the knob.
