The Husqvarna 577998901 Air Cleaner Canister Cap is a genuine OEM component designed for the FS513, FS520, and FS524 floor saws. As a direct Husqvarna OEM part, it is manufactured to the exact dimensions and specifications of the original, ensuring a secure, airtight fit on the air cleaner canister assembly. This cap is the correct replacement for FS513, FS520, and FS524 operators looking to restore the air filtration system to full working order. DHS Equipment supplies this part to help keep your equipment running at peak performance.
Key Features
- OEM-Matched Seal Integrity — Manufactured to Husqvarna's exact tolerances, this cap maintains a consistent, airtight closure on the air cleaner canister, preventing unfiltered air from bypassing the filtration system.
- Drop-In Replacement Fit — Engineered to match the original mounting points and canister profile on the FS513, FS520, and FS524, so installation is straightforward with no reworking of surrounding components.
- Correct Fitment for FS513, FS520, and FS524 Floor Saws — Verified for these three Husqvarna floor saw models; cross-reference 577998901 against your parts diagram to confirm application before ordering.
- Protects Engine Air Supply — A properly seated cap keeps the air cleaner canister sealed against concrete dust and debris — critical in the high-particulate environments where floor saws operate.
- Genuine Husqvarna OEM Part — Sourced directly from Husqvarna's construction equipment parts program, ensuring the material grade and dimensional accuracy match the component it replaces.
The Air Cleaner Canister Cap seals the top of the engine's air filtration canister, keeping the filter element properly contained and the intake path closed to contaminants. In floor saw applications, where operators are cutting through concrete and masonry, maintaining a secure cap is essential — a cracked, missing, or ill-fitting cap allows fine silica dust to enter the air intake and reach the engine, accelerating wear on internal components. Replacing a damaged cap with the correct OEM part restores the integrity of the air filtration system and helps protect the engine from premature failure.
