Description
This 44mm brushcutter cylinder kit provides the main components needed to repair the top end of compatible 52cc two-stroke brushcutters and strimmers. Winzor produces the kit as an aftermarket replacement for common Chinese-manufactured engines that use a 44mm cylinder.
44mm brushcutter cylinder kit compatibility
The kit fits engines and machines marked:
- TL52
- CG520
- BC520
- 1E44F-5
- 44F-5
- Generic 52cc brushcutters with a 44mm cylinder
Manufacturers often sell these engines under different brand and model names. Therefore, compare the cylinder bore, mounting-hole positions, intake port and exhaust port with the original cylinder before ordering.
Complete repair package
The package includes:
- 44mm cylinder
- Piston
- Piston rings
- Piston pin and retaining clips
- Piston needle bearing
- Cylinder and exhaust gaskets
- Cylinder mounting bolts
- Spark plug
- Engine sealant
Because the kit includes the main fitting components, it supports a cleaner and more complete top-end repair. Additionally, new gaskets help seal the cylinder, intake and exhaust connections without reusing compressed parts.
Before installation, inspect the crankshaft bearings, connecting rod, carburettor connection, air filter and cooling fins. Also check the carburettor adjustment and fuel mixture. A lean mixture or intake leak can quickly damage the new cylinder and piston.
During assembly, coat the piston, rings, needle bearing and cylinder wall with clean two-stroke oil. After installation, rotate the crankshaft by hand and confirm that the engine moves freely.
