LAHDEK 44 mm piston kit for Husqvarna 450 and 450E

This LAHDEK piston kit replaces OEM part 544088903 on Husqvarna 450 and 450E chainsaws. The package contains one piston, one pin, one ring and two circlips. It is a new replacement part for two-stroke single-cylinder petrol engines.

Suits owners repairing a 450 or 450E saw.

The kit fits Husqvarna 450 and 450E chainsaws that use a 44 mm piston with a 10 mm pin. Owners of different Husqvarna models or other brands should look for a kit matched to their specific engine. Builders needing a complete cylinder assembly will need additional parts.

44 mm piston diameter with 10 mm pin OD

The critical specification is the 44 mm piston diameter combined with a 10 mm pin outside diameter. These dimensions must match the original engine exactly for correct fit and compression.

Questions about this item

Will the 44 mm piston fit my Husqvarna 450 cylinder bore?

Yes — the piston is manufactured at 44 mm diameter to match the original bore on the Husqvarna 450 and 450E chainsaws.

Which circlip goes in first when I assemble the pin?

Install one circlip in the piston groove first, slide the 10 mm pin through the connecting rod, then seat the second circlip to lock the pin in place.

How often should I replace the piston ring on this 450 saw?

Inspect the ring at every top-end service; replace it when the end gap exceeds the service limit or if compression drops noticeably.
