TB110 Air Filter Cover Base Assembly Kits for Troy Bilt TB110 TB115 TB200 TB230 TB330 TB370 Walk Behind Lawn Mower

What It Is

This is a replacement air filter cover base assembly for Troy-Bilt TB110, TB115, TB200, TB230, TB330, and TB370 walk-behind lawn mowers. It houses and secures the air filter, sealing the intake system against debris and ensuring proper airflow to the engine.

Fitment & Compatibility

• Models: Fits Troy-Bilt TB110, TB115, TB200, TB230, TB330, and TB370. Not compatible with other brands or non-Troy-Bilt engines.
• Check your deck size: These models typically use 21” or 22” steel decks, but the cover base is engine-specific—verify your mower’s engine model (e.g., Briggs & Stratton or Troy-Bilt branded).
• OEM vs aftermarket: This is an aftermarket kit. Measure the existing cover base width and screw hole spacing (typically ~3.5” wide with two mounting holes ~2.5” apart). Compare to photos.
• Part number cross-reference: Look for OEM part numbers like 753-06108 or 753-06108A on your old base to confirm fit.

Key Things to Know

• Quality: Plastic construction is adequate but less rigid than OEM. Avoid overtightening screws to prevent cracking.
• Installation: Easy—remove old cover, swap the base, reinstall filter and cover. No special tools required.
• Common gotcha: The included screws may not match your mower’s thread pattern. Keep your original screws if possible.
• Filter fit: Ensure your air filter (typically a foam or paper rectangle) fits snugly inside the new base. Some aftermarket bases are slightly loose.

Should You Buy It

If your original cover base is cracked, missing, or warped and you need a quick, affordable fix for a TB110–TB370 mower, this kit works. It’s not as durable as OEM but gets the job done for the price. Skip it if you want a perfect fit or have a different model.
