Fitment and Purpose

This set of six piston rings is manufactured for STIHL 018, MS180 and MS 180 chainsaws. It replaces OEM part number 1130 034 3002 and suits two-stroke petrol engines requiring a 38mm bore with a 1.2mm ring thickness. Homeowners and professionals servicing these specific models will find the correct dimensions in one pack.

What the Pack Changes

Six rings are supplied so a complete engine rebuild or multiple future services are covered without reordering. Each ring matches the original 38mm x 1.2mm specification, restoring compression and oil control to factory levels. The quantity eliminates the need to source individual rings from separate listings.

Build and Daily Implications

The rings are produced to the stated 38mm x 1.2mm size for direct installation into the cylinder bore. No additional gaskets, tools or software are included in the package. Buyers needing a different bore diameter, ring thickness or a complete piston assembly should look elsewhere.

Questions about this item

When will the 38 mm x 1.2 mm rings need replacement?

Replace them whenever the piston is serviced or compression drops below specification for the STIHL 018 MS180 MS 180.

What fails first during extended cutting sessions?

Heat buildup in the two-stroke cylinder can reduce ring tension before other components show wear.

How hot and loud does the saw run with these rings fitted all day?

The rings themselves add no noise or heat; the petrol two-stroke engine determines temperature and sound levels.
