The Multiquip 1629221050 Piston Ring Assembly is a genuine OEM component designed for the HTH44T hydrostatic ride-on trowel. Sourced directly from Multiquip, this assembly carries the same specifications as the original part installed at the factory, ensuring a direct, compatible installation in HTH44T machines. When replacing worn or damaged piston rings, using the correct OEM assembly helps restore proper compression and engine performance to your trowel.
Key Features
- OEM-Grade Compression Tolerancing — Each ring in the assembly is manufactured to the same dimensional specifications as the original, maintaining proper cylinder seal and compression pressure.
- Direct-Install Compatibility — Engineered as a drop-in replacement for the HTH44T, the assembly aligns with the original ring grooves and bore dimensions without fitment guesswork.
- Confirmed HTH44T Fitment — Verified for use on the Multiquip HTH44T hydrostatic ride-on trowel series, so you can order with confidence.
- Restores Full Engine Output — A correctly seated piston ring assembly re-establishes the combustion seal needed for the engine to deliver full power to the trowel's hydraulic drive system.
- Prevents Oil Consumption and Blowby — Worn rings allow combustion gases and oil to bypass the piston, leading to smoke, oil loss, and progressive engine damage — a fresh OEM assembly stops this at the source.
The piston ring assembly forms a dynamic seal between the piston and the cylinder wall inside the engine. Its primary role is to contain combustion pressure above the piston, which converts fuel energy into the mechanical power that drives the machine. The rings also regulate oil by preventing excessive amounts from entering the combustion chamber. When piston rings wear, lose tension, or break, the engine loses compression, consumes oil, and produces noticeably less power — conditions that will quickly degrade the performance of a ride-on trowel that depends on consistent hydraulic output to finish concrete effectively.
