The Multiquip 45423 Heat Shield MRX is a genuine OEM component designed for LD6, LD6SL, and LD60 series ride-on power trowels. As a direct OEM replacement, part 45423 is manufactured to the same specifications as the original, ensuring a correct fit without guesswork or rework. DHS Equipment sources this part directly through authorized Multiquip supply channels, so you can order with confidence knowing you're receiving the authentic component. Verify your model against the LD6, LD6SL, or LD60 fitment list before ordering to confirm compatibility.
Key Features
- Genuine OEM Heat Management: — Manufactured to Multiquip's original material and dimensional specs, ensuring the shield properly deflects and contains heat away from adjacent components on LD6-series trowels.
- Direct-Fit Replacement: — Engineered to mount in the original installation position, matching existing fastener locations and clearances on LD6, LD6SL, and LD60 machines.
- Confirmed Fitment: — Verified for use on Whiteman ride-on power trowel models LD6, LD6SL, and LD60.
- Thermal Protection for Engine-Adjacent Parts: — A functioning heat shield keeps surrounding components — hoses, wiring, and structural members — within safe operating temperatures during extended troweling runs.
- Fire and Burn Hazard Mitigation: — Heat shields are a safety-critical component; running a trowel with a damaged or missing shield exposes fuel lines and hydraulic hoses to radiant heat that can cause premature deterioration or ignition risk.
A heat shield is a protective barrier positioned between a high-temperature source — typically the engine exhaust system — and surrounding machine components. Its job is to redirect and dissipate radiant heat so that nearby hoses, wiring, hydraulic lines, and structural parts stay within their designed temperature range during operation. When a heat shield is cracked, warped, or missing entirely, those adjacent components are exposed to sustained radiant heat that accelerates wear, causes seal and hose failure, and can create a fire hazard on the jobsite. Replacing a damaged shield promptly is one of the simplest ways to protect the long-term integrity of the surrounding drivetrain and hydraulic system.
