Piston Rings Kit 48 mm x 15 mm

This kit contains four piston rings sized at 48 mm bore and 15 mm width. It is a new replacement part for petrol chainsaws. The components are built for two-stroke engines used in forestry and garden maintenance.

Fits Husqvarna and Jonsered models listed

The rings suit Husqvarna models 61, 365, 261, 262, 162, 165 and 265 plus Jonsered 625 and 630 saws. They replace original part number 503289015. Owners of other brands or unlisted models should verify dimensions before ordering.

Bore 48 mm and width 15 mm

The critical specification is the 48 mm bore diameter combined with a 15 mm ring width. If the cylinder bore or ring groove differs from these figures the kit will not seal correctly.

Questions about this item

How do I install the 48mm piston rings on a Husqvarna 365 and avoid the common mistake?

Use a ring compressor to squeeze each ring, stagger the end gaps evenly around the piston, then slide the assembly into the cylinder; forcing rings in without a compressor usually bends or snaps them.

What maintenance will the 48mm x 15mm rings need after installation on a Husqvarna 262?

No routine maintenance is required; the rings wear gradually and are replaced during a full engine rebuild when compression drops or the piston is removed for other work.

What limit appears first when running a Husqvarna 61 hard with these 15mm wide rings?

The thin 15mm ring cross-section transfers heat quickly, so sustained high-rpm cutting raises ring temperature until the oil film breaks down and blow-by increases.
