Multiquip 1629221115 Piston Kubota V105

The Multiquip 1629221115 is a genuine OEM Piston Kubota V105 designed for the HTH44T hydrostatic ride-on trowel. Sourced directly from Multiquip, this piston is manufactured to the same tolerances and material specifications as the original component installed at the factory. Correct fitment is confirmed for the HTH44T, so you can install with confidence and get your machine back to work without guesswork. As a genuine OEM part, it carries the full backing of Multiquip's parts program and integrates seamlessly with the Kubota V105 engine assembly.

Key Features

• Genuine OEM Piston Tolerancing — Machined to the exact bore diameter and compression height specs of the Kubota V105 engine, ensuring proper ring seal and combustion chamber geometry.
• Direct Engine Replacement — Drops into the Kubota V105 cylinder bore without modification, aligning with existing wrist pin, rings, and connecting rod hardware.
• Confirmed HTH44T Fitment — Engineered specifically for the HTH44T hydrostatic ride-on trowel; no cross-referencing or adaptation needed.
• Combustion Efficiency Restored — A worn or scored piston causes compression loss, oil burning, and uneven engine power; replacing with this part restores proper compression and smooth engine output.
• Long-Cycle Durability — Cast to OEM material standards so the piston withstands the thermal and mechanical stress of continuous troweling operations on the jobsite.

The piston is a core reciprocating component inside the Kubota V105 engine's cylinder bore. It transfers the force of combustion downward through the connecting rod to the crankshaft, converting fuel energy into the rotational power that drives the HTH44T's hydraulic system and blade control. When a piston wears, develops scoring, or cracks, compression drops sharply — leading to hard starting, excessive oil consumption, loss of blade speed, and ultimately engine failure. Replacing a damaged piston with the correct OEM part restores proper compression ratio and combustion efficiency, keeping the trowel performing at full capacity.
