Description
Overview:
Piston Pin with Needle Bearing Set for Stihl MS 400 C-M series chainsaws. This genuine Stihl OEM assembly replaces the small-end gudgeon pin and needle cage to restore correct fit and smooth rotation between the piston and connecting rod. The piston pin is made from hardened, ground steel for wear resistance, while the precision needle bearing supports low-friction movement to minimise heat and reduce small-end knock. Ideal when fitting a new piston and rings or refreshing a high-hour saw, this set keeps the piston accurately located and helps protect the cylinder and crank assembly. Supplied to Stihl specification under OEM No. 1140 034 1501, it offers a direct fit on compatible MS 400 C‑M variants. This is a Genuine Stihl OEM part.
Key Features:
- Genuine Stihl OEM small-end set for assured fit and reliability
- Includes matched hardened-steel piston pin and precision needle bearing
- Direct replacement to OEM specification; no modification required
- Helps prevent excessive small-end play and reduces vibration and noise
- Low-friction needle rollers for smoother running and better heat control
- Supports piston alignment to protect cylinder, rings, and crankshaft
- Suitable for routine top-end refreshes, rebuilds, or post-overheating repairs
- Built for durability in professional and heavy DIY use
Typical Applications:
Used during piston and ring replacement, full top-end rebuilds, or when diagnosing small-end wear, knock, or scuffing. Recommended after overheating or seizure events where the pin and bearing may be stressed, and as preventative maintenance on high-hour MS 400 C‑M saws to maintain smooth operation and service life.
