The Multiquip H001378 Rain Air Cap is a genuine OEM component designed for HTX44Y4 and HTX44Y5 hydrostatic ride-on power trowels. Sourced directly from Multiquip, this part matches the original specification installed at the factory, ensuring a correct, hassle-free installation. Verify your model code against the HTX44Y4 and HTX44Y5 fitment before ordering to confirm compatibility with your machine.
Key Features
- Genuine OEM Construction — Manufactured to the same material and dimensional standards as the original, so the cap seats and seals exactly as intended on the air intake.
- Direct-Fit Replacement — Engineered to drop into the existing mounting point on HTX44Y4 and HTX44Y5 trowels with no rework or adapter hardware needed.
- Confirmed Fitment — Verified for HTX44Y4 and HTX44Y5 Whiteman hydrostatic ride-on power trowels; always cross-reference part number H001378 against your machine's parts diagram.
- Intake Protection — Shields the air intake from rain, debris, and airborne particulate, helping the engine breathe clean air and maintain consistent power output during finishing operations.
- Corrosion-Resistant Design — Built to withstand the outdoor, wet-concrete environment typical of troweling work, maintaining its shape and seal over extended service life.
The rain air cap sits at the top of the engine's air intake stack and acts as the first line of defense against water ingestion and large debris. When the cap is cracked, missing, or improperly seated, rainwater and job-site particulate can bypass the air filter and enter the intake tract, accelerating engine wear and potentially causing a loss of power or unplanned shutdown. Replacing a damaged cap promptly with the correct OEM part keeps the intake system working as designed and protects the engine investment in the trowel.
