The Multiquip 21948 Air Intake Hose is a genuine OEM component designed for HTX44Y4 and HTX44Y5 heavy-duty hydrostatic ride-on power trowels. As a direct OEM replacement, this hose is manufactured to the same specifications as the original part, ensuring proper airflow routing to the engine with no fitment compromises. Sourced directly through authorized Multiquip channels, part 21948 is the correct replacement for HTX44 series machines running Yanmar diesel engines. DHS Equipment stocks this part ready to ship so you can get your trowel back in service fast.
Key Features
- Genuine OEM Construction — Manufactured to original Multiquip specifications, delivering the same intake hose material grade and dimensional tolerancing as the factory-installed component.
- Correct Routing and Connection Geometry — Designed to follow the exact intake path on HTX44 series trowels, connecting cleanly to the air intake system without trimming or adapting.
- Confirmed HTX44 Series Fitment — Verified for HTX44Y4 and HTX44Y5 hydrostatic ride-on power trowels equipped with Yanmar diesel engines.
- Protects Engine Air Supply — A properly sealed intake hose maintains consistent, unobstructed airflow to the engine; a cracked or collapsed hose allows unfiltered air in, accelerating internal engine wear.
- Fuel System and Engine Safety — Maintaining an intact air intake path is critical to correct air-fuel mixture and combustion efficiency — a deteriorated hose can cause rough running, power loss, or engine damage over time.
The air intake hose channels filtered air from the air cleaner assembly to the engine's intake, forming a sealed pathway that keeps dust, debris, and moisture out of the combustion system. On a ride-on power trowel operating in concrete finishing environments, where fine particulate is constantly present, a compromised intake hose allows abrasive material to bypass the filter and enter the engine directly. Over time this causes premature cylinder and piston wear, reduced engine output, and ultimately engine failure — making timely replacement of a cracked or deteriorated hose essential to protecting the machine.
