Atlas Copco Engine Cylinder B Class - OEM Number: 9234001419

The Atlas Copco Engine Cylinder B Class (OEM 9234001419) is a replacement engine cylinder designed for compatible Atlas Copco Cobra petrol breakers and related equipment. It forms the main cylinder within the engine assembly, providing the bore in which the engine piston travels during operation and containing the combustion forces required to generate mechanical power. Atlas Copco parts information lists 9234001419 specifically as the Engine Cylinder B Class.

The cylinder works as part of the Cobra engine assembly alongside the matching A-class piston, piston rings, crankshaft and associated components. It is designed for the high temperatures, pressures and repeated reciprocating movement encountered during operation, providing a replacement solution where the original cylinder is worn or damaged. Atlas Copco parts listings show the component used in Cobra TT and related Cobra petrol breaker assemblies.

IMPORTANT INFORMATION

The B-class designation is important when matching this cylinder to the corresponding piston and engine assembly. The associated 9234001420 A-class piston is listed alongside the cylinder in the applicable Atlas Copco parts information, so the existing piston and cylinder classification should be checked before ordering.

Always confirm the breaker model and serial number before fitting, as cylinder and piston arrangements can vary between engine versions. Inspect the piston rings, piston pin, crankshaft and cylinder gasket at the same time, particularly where cylinder wear or damage has led to an engine rebuild.
