48 mm Piston Kit for Husqvarna 61 and Jonsered 630

This new LAHDEK kit supplies a complete 48 mm piston assembly for Husqvarna 61 and Jonsered 630 chainsaws. It replaces OEM references 503517401 and 503260204. The package includes the piston, wrist pin, piston ring, two circlips, two oil seals and a needle bearing. It is intended for two-stroke petrol engines requiring a 48 mm bore.

Suits owners rebuilding a 48 mm two-stroke

The kit fits the specific 48 mm bore and 12 mm pin diameter used on the listed models. It is not for saws with a different bore size or a different pin diameter. Buyers who need a complete cylinder assembly or a different displacement should look elsewhere. The parts are sold as a replacement spare-part set only.

48 mm piston diameter and 12 mm pin OD

These two dimensions decide whether the kit matches your engine. Verify the original piston measures 48 mm across the skirt and that the wrist pin measures 12 mm outside diameter before ordering. The included needle bearing and oil seals are sized to those exact figures.

Questions about this item

Does the kit contain the piston, pin, ring, circlips, oil seals and needle bearing, or must any of those be ordered separately?

The package includes one piston, one pin, one ring, two circlips, two oil seals and one needle bearing, so no extra parts are needed for a complete rebuild.

How do I confirm this 48 mm kit fits my Husqvarna 61 or Jonsered 630 chainsaw?

Match the 48 mm piston diameter and 12 mm pin OD to your cylinder, and cross-reference OEM numbers 503517401 and 503260204 stamped on the original parts.

What does the 48 mm piston diameter mean once the kit is installed in the saw?

It restores the original 48 mm bore size on the two-stroke engine, matching the factory compression and displacement for Husqvarna 61 and Jonsered 630 models.
