44 mm Piston Rings for Husqvarna Chainsaws

These six piston rings are manufactured by LAHDEK as direct replacements for Husqvarna chainsaw engines. Each ring measures 44 mm by 1.5 mm and matches the original equipment part number 503289010. The set covers a wide range of models including 49, 42, 51, 55, 246, 351, 353, 350, 345, 340 and 346 as well as Jonsered 2150 CS2150 saws.

Suited to owners servicing listed two-stroke

The rings fit the specific Husqvarna and Jonsered models named above and are intended for standard engine rebuilds on those units. They are not suitable for saws with a different bore diameter or for four-stroke engines. Buyers needing rings for other displacements or for diesel power equipment should look elsewhere.

44 mm bore with 1.5 mm ring width

This single dimension determines whether the parts will seal correctly in the cylinder. Verify that the engine being repaired calls for a 44 mm piston and a 1.5 mm ring groove before ordering.

Questions about this item

Does this 44 mm piston-ring set include the piston itself or only the rings?

The package contains six 44 mm piston rings measuring 44 mm by 1.5 mm; the piston is not included.

Will these rings fit a Husqvarna 346 chainsaw that still has its original 503289010 cylinder?

Yes, the rings replace OEM part 503289010 and are listed for the Husqvarna 346 among other models.

After installing the rings, how can I confirm they are sealing correctly on the 44 mm bore?

Perform a compression test on the 2-stroke petrol engine; readings within the saw's specified range indicate a proper seal.
