Multiquip 13101ZJ1000 Piston STD

The Multiquip 13101ZJ1000 is a genuine OEM standard piston designed for a wide range of Multiquip and STOW equipment, including SP2, SP2S, CC8CE13H20, CS8CE13H20, SGW-250SS, and GA-9.7 series machines. As a factory-sourced component, this piston is manufactured to the exact tolerances required by the original engine specification, ensuring proper compression, ring seal, and power delivery. Verified fitment spans Stow pavement saws, Street Pro flat saws, portable generators, and arc welders — making 13101ZJ1000 a widely applicable OEM engine component across the Multiquip portfolio.

Key Features

• OEM Compression Tolerance: — Manufactured to the original engine bore specification, maintaining correct compression ratio and combustion efficiency across all fitted models.
• Direct Engine Drop-In: — Matches the original piston crown geometry and pin bore dimensions for installation without additional machining or fitting work.
• Broad Equipment Fitment: — Compatible with SP2, SP2S, CC8CE13H20, CS8CE13H20, CS813H20, CS820H20, SGW-250SS, GA-9.7, and additional STOW pavement saw and flat saw models.
• Sustained Engine Output: — A correctly fitted piston maintains ring seal and combustion pressure, preserving the full horsepower output your saw, welder, or generator depends on under load.
• Fuel System Integrity: — Proper piston-to-wall clearance prevents blow-by, protecting the oil supply and reducing the risk of contamination in fuel-sensitive applications like portable generators and welders.

The piston is the core reciprocating component inside the engine cylinder, converting combustion pressure into the mechanical force that drives the crankshaft. It works in direct partnership with the piston rings and cylinder wall to seal the combustion chamber and transfer energy efficiently. When a piston wears beyond spec — or sustains damage from overheating or detonation — compression drops, oil consumption rises, and the engine loses the power and consistency needed to drive a saw blade, generate stable current, or sustain welding output.
