45 mm × 1.2 mm piston ring kit

This 10-piece set supplies replacement piston rings sized 45 mm by 1.2 mm for Husqvarna 353 and 350 chainsaws. It matches OEM part number 537253002 and is built for two-stroke, single-cylinder petrol engines. The pack contains exactly ten rings for a full rebuild.

Replaces worn original rings on 353 and 350 models

Swap the rings when compression drops or the saw smokes under load. The upgrade is worth it if the cylinder bore is still within specification and the piston shows no deep scoring. It is not for engines with oversize bores or for models outside the 353 and 350 range.

Simple press-on fit with basic tools

Remove the cylinder, slide the old rings off the piston groove and press the new rings into place, taking care not to over-expand them. The most common error is twisting a ring until it snaps or installing a ring with the end gap facing the wrong port. Clean the groove thoroughly before assembly.

Questions about this item

What bore size and ring thickness do these 45mm x 1.2mm piston rings suit on a Husqvarna 353 or 350 chainsaw?

The rings are manufactured to 45mm bore diameter and 1.2mm thickness, matching the OEM 537253002 specification for the Husqvarna 353 and 350 single-cylinder two-stroke engines.

How do I install the 10 piston rings on the Husqvarna 353 and 350 without damaging the ring lands?

Clean the groove thoroughly, expand each ring just enough to clear the piston, seat it with the marking facing up, and ensure the end gaps are staggered around the piston circumference.

When should the 45mm x 1.2mm piston rings on my Husqvarna 353 or 350 be replaced again?

Replace the set when compression drops below specification, the ring end gap exceeds the service limit, or during any top-end rebuild after prolonged two-stroke petrol operation.
