The Multiquip 13101ZM5030 Piston HC- GX22/31SA DSGPU is a genuine OEM piston designed for GX22 engine-equipped Multiquip equipment. As a direct OEM replacement, this piston is manufactured to the same tolerances and specifications as the original component, ensuring proper fit within the cylinder bore. Sourced directly through authorized Multiquip supply channels, this part is the correct choice when rebuilding or servicing a GX22-powered unit. Confirm your engine model and part number against your machine's parts manual before ordering to ensure full compatibility.
Key Features
- OEM-Grade Dimensional Accuracy — Manufactured to the same bore diameter, ring groove dimensions, and pin bore tolerances as the original, ensuring correct compression and piston-to-wall clearance in GX22 and 31SA DSGPU engine applications.
- Drop-In Engine Replacement — Designed to install directly into the cylinder bore without machining or modification, accepting the original piston pin and ring set for a straightforward engine rebuild.
- GX22 Engine Fitment — Confirmed fitment for GX22 engine configurations as referenced by model code GX22, commonly found across Multiquip equipment platforms utilizing this small-displacement Honda-type powerhead.
- Restored Compression and Power Output — A worn or scored piston causes loss of compression, excessive oil consumption, and reduced power; replacing it with a correctly spec'd OEM piston restores engine performance to original operating levels.
- Genuine OEM Part — Supplied as an authentic Multiquip OEM component under part number 13101ZM5030, backed by the same quality standards applied to original production units.
The piston is the reciprocating component inside the engine cylinder that converts the force of combustion into rotational crankshaft movement. It must maintain a precise fit within the cylinder bore to seal combustion pressure above it while allowing oil to lubricate the cylinder walls below. Over time, heat cycles and friction can cause a piston to wear, score, or crack — resulting in lost compression, increased blow-by, oil burning, and ultimately engine failure. Replacing a damaged piston with a correctly dimensioned OEM part is a fundamental step in any engine rebuild and directly determines whether the engine returns to full operating power after service.
