841-036210S Air Cleaner Cover - Fits MTD/Craftsman (WS405/WS4200)/Troy-Bilt (TB304CEC/TB304H/TB304S) Replacement Part (1 Pack)

This 841-036210S Air Cleaner Cover is a dedicated protective part for outdoor power equipment, compatible with Craftsman models (WS405, WS4200) and Troy-Bilt models (TB304CEC, TB304H, TB304S). It is designed to protect the engine's air filter, preventing dust, grass clippings, and other impurities from entering the engine intake system, which ensures stable engine operation and extends service life.​ Made of high-impact plastic, it can withstand accidental collisions and drops during equipment use, avoiding cracks or damage. The snap-in closure design allows quick disassembly—no tools are needed to open the cover when replacing the air filter, improving maintenance efficiency. The precision edge sealing fits tightly with the air filter housing, eliminating gaps that may allow unfiltered air to bypass the filter and enter the engine, ensuring the filtering effect.​ With standard dimensions (length 5.2IN, width 3.8IN, height 2.1IN) and 2.5IN mounting hole spacing, it perfectly matches the original air cleaner housing of compatible equipment. Installation only requires aligning the cover with the housing and pressing the into place—no drilling or modification is needed. The dust-resistant surface is easy to clean; simply wipe with a dry cloth to remove attached dust, keeping the cover in good condition.​ It solves problems caused by damaged air cleaner covers (such as unfiltered air entering the engine, increased fuel consumption, reduced engine power) and restores the protective function of the air filter system, suitable for long-term use in lawn mowing and garden maintenance scenarios.
