Multiquip 45493 Exhaust MRX

The Multiquip 45493 Exhaust MRX is a genuine OEM exhaust component designed for Whiteman ride-on power trowels, specifically the LD6, LD6SL, and LD60 series. Sourced directly from Multiquip, part 45493 is built to the same specifications as the original unit it replaces, ensuring a correct, hassle-free installation. This is the exact part called out for these machines, so you can order with confidence knowing it will seat and seal properly without modification. Keeping the exhaust system in good condition is essential to safe, compliant machine operation on any flatwork project.

Key Features

• Genuine OEM Construction — Manufactured to Multiquip's original design tolerances, ensuring the correct wall thickness, port dimensions, and material grade for this exhaust application.
• Direct-Fit Replacement — Engineered to bolt directly into the exhaust position on LD6, LD6SL, and LD60 trowels using the original mounting points and hardware.
• Confirmed Fitment — Verified for Whiteman LD6, LD6SL, and LD60 ride-on power trowel models; always cross-reference your model code before ordering.
• Proper Exhaust Flow — A correctly functioning exhaust MRX maintains engine back-pressure within spec, supporting consistent power output and smooth trowel blade operation during finishing passes.
• Emissions and Safety Compliance — As a fuel combustion exhaust component, using the correct OEM part helps maintain proper venting of exhaust gases, supporting operator safety and regulatory compliance on the jobsite.

The exhaust MRX on a ride-on power trowel channels combustion gases away from the engine and directs them safely out of the machine. A damaged or deteriorated exhaust component can cause exhaust gas leakage near the operator area, increased engine noise, and potential overheating from disrupted flow. Replacing a worn exhaust MRX with the correct OEM part restores proper engine venting and keeps the trowel running at full efficiency during concrete finishing operations.
