Description
Overview:
This Piston Pin 12x8x35 is a Genuine Stihl component designed to connect the piston to the connecting rod in two‐stroke chainsaw engines. Built from high‐strength steel for long service life, it provides a stable, low‐friction pivot to keep the piston moving smoothly and accurately. Sized precisely at 12 x 8 x 35 mm (approx. 0.47 x 0.31 x 1.38 inches), it fits selected Stihl professional saws, including the 046 and 044. It is an exact replacement identified by MPN 1128 034 1501, ensuring correct fit and compatibility without modification. Ideal for routine overhauls or repairs, it helps maintain compression, reduce noise from piston slap, and protect the small‐end bearing under heavy cutting loads.
