LAHDEK 38 mm piston rings for STIHL 018 MS180

This four-piece set replaces OEM part 1130 034 3002 on STIHL 018 MS180 MS 180 chainsaws. Each ring is sized at 38 mm for the two-stroke petrol engine. The kit suits owners performing a top-end rebuild or routine ring replacement. It is not for saws with a different bore or for four-stroke engines.

Sustained compression retention in two-stroke use

The rings maintain cylinder seal during extended cutting sessions where heat builds steadily. They resist the gradual loss of compression that degrades power on long jobs. The pack provides enough rings for a full piston refresh or for spares during a season. They do not address wear on the cylinder bore itself.

Simple press-on fit with standard tools

Installation follows the usual piston-ring procedure: expand each ring just enough to slide over the piston into its groove. No special fixtures are required beyond basic hand tools. The main risk is snapping a ring by over-expanding it or seating a ring upside-down, which breaks the seal. Builders who need a complete piston assembly will need additional parts.

Questions about this item

Will the 38 mm piston rings keep the Stihl 018 MS 180 running cool during long cutting sessions?

The rings are made to the original 38 mm bore size so they seal the cylinder properly and maintain normal engine temperature under load.

What other parts do I need to install these 1130 034 3002 rings on my MS 180?

You will need a piston that matches the 38 mm bore, a wrist pin, circlips and fresh two-stroke fuel mix to complete the rebuild.

Can I use these rings on an older Stihl 018 that still has the original cylinder?

Yes, they are direct replacements for part 1130 034 3002 and fit the 38 mm cylinder used on both the 018 and MS 180 models.
