Description
Overview:
This Piston Ring 47 x 1.5 mm is a genuine Stihl OEM part designed to restore and maintain engine compression in Stihl cut-off saws and other small two-stroke machinery. Built to Stihl's factory specifications, it fits a 47 mm bore (approximately 1.85 in) with a 1.5 mm thickness (approximately 0.06 in). Correct compression is vital for easy starting, steady idle, and full cutting power, especially under load. Suitable for disc cutters such as the TS08 and TS08S, it replaces worn or damaged rings to prevent power loss and excess fuel consumption. Supplied under Manufacturer Part Number (MPN) 1108 034 3001, this ring is manufactured to match the original fit and clearances, helping extend engine life when installed as part of routine top-end maintenance.
Key Features:
- Genuine Stihl OEM part for assured compatibility and performance
- Dimensions: 47 mm bore x 1.5 mm thick (1.85 in x 0.06 in) for the correct cylinder size
- Helps restore sealing and compression for reliable starting and strong cutting power
- Supports fuel efficiency and smoother running by limiting blow-by
- Precision-made to OEM tolerances for proper end gap and ring seating
- Durable construction for long service life in harsh, dusty cutting environments
- Direct replacement; fits the original piston and cylinder without modification
- Suitable for routine rebuilds and preventative maintenance on ageing engines

- Supplied under MPN 1108 034 3001 for easy identification
Typical Applications:
Used during top-end overhauls or scheduled maintenance of Stihl disc cutters and similar small engines to recover lost compression, improve throttle response, and stabilise idle. Ideal when engines are hard to start, down on power, smoking, or have high hours in concrete, masonry, or roadwork cutting tasks.
