Description
Overview:
This Piston Assembly 40mm is a non-genuine replacement for selected Stihl top-handle chainsaws, including the 020T and MS200T. It is designed to restore compression and reliable running in a 40 mm cylinder. The piston is typically made from lightweight aluminium alloy for good heat transfer and durability, with steel piston rings and a hardened steel gudgeon pin to withstand high loads. Supplied as a complete kit with rings, circlips, and gudgeon pin, it supports an efficient top-end refresh when the original piston is worn or damaged. Built to match the critical dimensions of the OEM part, it offers a straightforward refit and dependable sealing so your saw can start easily, idle cleanly, and pull strongly under load. MPN: 350 027.
Key Features:
- Non Genuine Part compatible with selected Stihl 40 mm top-end setups
- 40 mm piston sized for correct fit and reliable compression in the cylinder
- Aluminium alloy piston for strength-to-weight efficiency and heat dissipation
- Steel piston rings for durable sealing and consistent performance
- Hardened steel gudgeon pin and circlips included for a complete installation
- Supplied as a ready-to-fit kit: piston, rings, circlips, and gudgeon pin
- Helps restore power, throttle response, and fuel efficiency after wear
- Direct replacement design to reduce downtime and complexity during rebuilds
- Suitable for routine maintenance or top-end repair after scoring or seizure
- Cost-effective solution when a full cylinder kit is not required
Typical Applications:
Used during top-end rebuilds on professional and domestic chainsaws to recover compression and smooth running. Ideal after ring wear, piston scoring, or minor seizure, and as preventative maintenance on high-hour saws. Supports reliable cutting performance for arborists, ground workers, landscapers, and property maintenance when processing timber, pruning, or general felling work.
