5200 Cylinder and Piston Kit 45mm for Generic 52cc Chainsaws – Winzor PRO

Description

This 5200 cylinder and piston kit is a Winzor PRO replacement engine assembly for compatible generic Chinese and Polish 5200 chainsaws. It features a 45mm cylinder bore and a coated 45mm piston for rebuilding a worn or damaged two-stroke engine.

The kit replaces damaged components that cause low compression, difficult starting, weak performance or excessive piston and cylinder noise.

5200 Cylinder and Piston Kit Compatibility

Designed for compatible 5200 and 52cc chainsaws sold under various importer brands, including:

• BIZON
• HARDER
• NAC
• STEEL
• VICTUS
• Generic CS5200, PN5200 and YD5200 chainsaws
• Other 52cc two-stroke chainsaws using the same 45mm cylinder design

Generic chainsaws can use different cylinder versions despite having similar model names. Therefore, compare the cylinder bore, mounting holes, intake port, exhaust port and transfer-port layout with the original part before ordering.

Kit Contents

The Winzor PRO kit contains:

• 45mm cylinder
• Coated 45mm piston
• Two piston rings
• Piston pin
• Two piston-pin circlips
• Cylinder gasket
• Spark plug
• Engine sealant

Product Details

• Product type: cylinder and piston assembly kit
• Brand: Winzor
• Product reference: SCSET-03PRO
• Cylinder bore: 45mm
• Application: generic 5200 chainsaw

The coated piston reduces friction during initial operation and provides additional protection to the piston skirt. Meanwhile, the matched cylinder and piston restore the engine’s compression chamber when fitted correctly.

Important Size Information

This kit uses a 45mm bore. Do not confuse it with:

• Generic 4500 cylinders with a 43mm bore
• Generic 5800 cylinders with a 45.2mm bore
• Other 5200 cylinder designs with different ports or mounting points

Before assembly, clean the crankcase mating surface and inspect the crankshaft, connecting rod and small-end bearing. Lubricate the piston, rings and cylinder with two-stroke oil during installation. Afterwards, check the assembled engine for intake and crankcase air leaks before operation.
