The Multiquip X430440142 Fuel Cap is a genuine OEM replacement designed for JH55C, JH90C, and JS60C Whiteman walk-behind power trowels. As a direct OEM component, it is manufactured to the same specification as the original part, ensuring a correct seal and proper venting on your machine's fuel system. This cap is confirmed for use across the JH55C, JH90C, and JS60C trowel models, making it a straightforward swap during routine maintenance or after damage to the original.
Key Features
- OEM Sealing Integrity — Engineered to the original compression and thread specification, delivering a fuel-tight seal that prevents leaks and contamination during operation.
- Direct-Fit Installation — Matches the original tank filler neck thread pattern on Whiteman walk-behind trowels for a straightforward, tool-free swap.
- Confirmed Trowel Fitment — Verified for JH55C, JH90C, and JS60C walk-behind power trowel models.
- Fuel System Protection — A properly functioning fuel cap keeps debris, moisture, and contaminants out of the tank, protecting the carburetor and fuel delivery components from premature wear.
- Fuel Venting Compliance — Correct OEM venting behavior prevents fuel starvation and vacuum lock that can cause engine hesitation or hard starting on the trowel.
The fuel cap seals the opening of the fuel tank to prevent fuel spills, vapor escape, and contamination from dirt or moisture entering the system. Most OEM caps also incorporate a small vent that allows air to replace fuel as it is consumed, preventing a vacuum from forming that would restrict fuel flow to the engine. A cracked, missing, or poorly seating cap can introduce debris into the fuel system, cause fuel to leak during operation, or starve the engine of fuel through vacuum lock — any of which will interrupt work and may cause downstream damage to the carburetor or fuel lines.
