Multiquip 366345980 Air Filter Cover Knob

The Multiquip 366345980 Air Filter Cover Knob is a genuine OEM component designed for MTX-series rammers including the MTX50HD, MTX60HD, MTX60HF, MTX70HD, MTX70HF, MTX70HDR, and MTX80HDR. As a direct OEM replacement sourced from Multiquip, this knob matches the original part exactly — no fitting, modification, or guesswork required. It is the correct specification for maintaining proper air filter cover retention on these tampers. If you are servicing or rebuilding a Multiquip MTX rammer, using part number 366345980 ensures you are installing the component the machine was built with.

Key Features

• Genuine OEM Construction — Manufactured to the same specification as the original knob, ensuring correct thread engagement and secure cover retention on the air filter housing.
• Direct Drop-In Replacement — Designed to thread directly onto the air filter cover post on MTX-series rammers with no rework or adaptation needed.
• Broad MTX-Series Fitment — Compatible with MTX50HD, MTX60HD, MTX60HF, MTX70HD, MTX70HF, MTX70HDR, and MTX80HDR rammers.
• Keeps the Air Filter Sealed and Secured — A properly functioning cover knob holds the air filter housing closed, preventing dust and debris from bypassing the filter and entering the engine.
• Small Part, Big Consequence — A missing or damaged knob leaves the air filter cover unsecured, exposing the engine to contaminant ingestion that accelerates wear and causes performance loss.

The air filter cover knob secures the air filter housing cover on the rammer, keeping it firmly closed during operation. Without it, the cover can loosen or detach, allowing unfiltered air — carrying dust, dirt, and debris from the compaction site — to reach the engine intake. Over time, this leads to accelerated cylinder and piston wear, loss of compression, and engine damage. Replacing a worn, stripped, or missing knob with the correct Multiquip 366345980 is a low-cost step that protects a much more expensive engine.
