LAHDEK 48mm Piston Kit for Husqvarna 61

This LAHDEK kit supplies a complete piston assembly for the Husqvarna 61 chainsaw. It replaces OEM references 503 53 90 02 and 503539002. The package includes piston, pin, ring, circlips, cylinder gasket, crank bearings and oil seals. It is intended for owners servicing a 48mm single-cylinder two-stroke petrol engine.

Verify piston diameter and pin size before ordering

Confirm the cylinder bore measures 48mm and the wrist pin outside diameter is 12mm. Cross-reference the original part numbers 503 53 90 02 or 503539002 on your existing component. This kit suits the Husqvarna 61 model only and will not fit saws with different bore or pin dimensions.

Kit contents cover top-end and lower-end seals

The set provides the cylinder gasket, two crank bearings and two oil seals alongside the piston components. Installing the kit refreshes both compression and crankcase sealing in one operation. No additional gaskets or bearings are included for other engine sections such as the clutch or ignition side.
