The Multiquip 14721Z6L000 Exhaust Valve is a genuine OEM component designed for JWN24HTCSL Whiteman ride-on power trowels and AR14H asphalt rollers. As a direct OEM replacement, this valve is manufactured to the same specification as the original, ensuring a correct seat fit and proper sealing within the engine's cylinder head. Sourced directly through authorized Multiquip supply channels, 14721Z6L000 is the confirmed part number for compatible equipment and is stocked by DHS Equipment for fast order fulfillment.
Key Features
- OEM-Grade Valve Material — Manufactured to original specification with the correct alloy composition and head geometry to withstand high exhaust-side heat and combustion pressure cycles.
- Correct Stem Diameter and Seat Profile — Drops into the existing valve guide and seats against the cylinder head without recutting or shimming, maintaining the original valve-to-seat contact angle.
- Confirmed Fitment — Verified for JWN24HTCSL Whiteman ride-on power trowels and AR14H asphalt rollers; cross-reference part number 14721Z6L000 before ordering.
- Full Combustion Seal Restored — A correctly functioning exhaust valve seals combustion gases on the power stroke and opens precisely on the exhaust stroke, maintaining compression and engine output. A worn or burned valve causes misfires, power loss, and excessive blowby.
- Fuel System and Emissions Integrity — A properly seating exhaust valve prevents raw combustion gases from contaminating the intake or crankcase, keeping fuel consumption and exhaust output within normal operating range.
The exhaust valve is a critical engine component that opens and closes in precise timing with the crankshaft to release burned combustion gases from the cylinder. It must form a gas-tight seal against its seat when closed to preserve compression pressure — without this seal, the engine loses power, runs rough, and can suffer accelerated wear to surrounding components. When an exhaust valve burns, warps, or wears at the stem, compression drops noticeably and combustion efficiency deteriorates, making timely replacement essential to restoring full engine performance.
