Cylinder and Piston Kit for STIHL 018 / MS 180 – 38 mm – GEKO G81113
A complete cylinder and piston kit designed for rebuilding STIHL 018 and MS 180 petrol chainsaws. An aftermarket replacement for the original piston and cylinder assembly, with a chrome-plated 38 mm bore.
Piston and Cylinder Assembly Features
Chrome-plated cylinder bore
The chrome plating increases wear resistance and gives the piston rings better sliding properties. The chrome layer protects the cylinder from scoring and extends engine life.
Complete fitting kit
Contains every component needed for replacement: cylinder, piston, two piston rings, gudgeon pin and circlip. No additional parts need to be purchased.
38 mm bore
Matches the original specification of the STIHL 018 and MS 180 models. The cylinder bore determines engine displacement and chainsaw power – in this case approximately 31.8 cm³.
Replacement for the factory assembly
An aftermarket alternative to original STIHL parts. It retains the original dimensions and fitting parameters, so it can be fitted directly without modification.

Applications
The kit is designed for rebuilding the following STIHL chainsaw models:
- STIHL 018 – older petrol chainsaw model
- STIHL MS 180 – popular chainsaw with approximately 1.5 hp
- Replacement after cylinder wear (scoring, loss of compression)
- Repair after engine seizure
- Engine rebuild after long-term use
How to check compatibility
Before purchase, verify the chainsaw model on the rating plate or in the instruction manual. Make sure the original cylinder bore is 38 mm. If in doubt, measure the diameter of the old piston or cylinder.
Fitting and Maintenance
Replacing the piston and cylinder assembly requires basic mechanical tools and knowledge of how a two-stroke engine is put together. During fitting, the following steps should be observed:
- Thoroughly clean the ports and openings in the engine crankcase
- Lubricate the gudgeon pin before seating it in the piston
- Check the piston ring clearance in the ring grooves
- Position the ring end gaps so that they are staggered (120° apart)
- Coat the cylinder bore with engine oil before the first start-up
- Run in the engine in accordance with the chainsaw manufacturer's recommendations
Running in a new cylinder
After fitting a new piston and cylinder assembly, a running-in period is recommended – the first 3–5 hours of operation at reduced engine speed, avoiding full load. This allows the rings and the cylinder surface to bed in optimally.
