The Multiquip 13101Z5T800 is a genuine OEM Standard Piston designed for GA6HB, GA6HEB, GAW180HE, GAW180HE1, GAW180HEA, MC12PH, and MRH800GS series equipment. As a direct OEM component sourced through Multiquip's authorized parts supply chain, this piston meets the precise tolerances required for reliable engine operation across the full range of compatible machines. Verify your model code against the fitment list before ordering to confirm this is the correct standard-bore specification for your engine. DHS Equipment stocks genuine Multiquip parts so you can get the right component the first time.
Key Features
- OEM Bore Tolerancing — Manufactured to the exact standard bore diameter and crown geometry specified for the original Honda-powered engine, ensuring correct compression and ring seal.
- Drop-In Engine Replacement — Engineered to locate on the connecting rod and seat within the cylinder bore using the same pin and ring configuration as the factory piston.
- Broad Model Compatibility — Fits GA6HB and GA6HEB generators, GAW180HE-series arc welders, MC12PH concrete mixer, and MRH800GS roller — one part number across multiple equipment families.
- Compression Integrity — A correctly fitted piston maintains the combustion chamber seal that the engine depends on for rated power output; a worn or scored piston causes oil consumption, loss of compression, and hard starting.
- Standard Specification — Supplied at standard (STD.) bore size, making this the correct choice for engines with an unworn or freshly honed cylinder that does not require an oversize piston.
The piston is the reciprocating component at the heart of the combustion engine. It travels up and down inside the cylinder bore, compressing the air-fuel mixture on the upstroke and transferring the force of combustion downward through the connecting rod to turn the crankshaft. Piston rings fitted around the piston create a seal that maintains compression and prevents combustion gases from entering the crankcase. When a piston becomes worn, scored, or cracked — whether from heat, lack of lubrication, or extended hours — compression drops, oil consumption increases, and the engine loses the power it needs to drive the generator, welder, mixer, or roller it is installed in. Replacing the piston with a genuine OEM part restores that combustion seal and brings engine output back to specification.
