Description
Overview:
This tension spring is a genuine Stihl OEM component for small petrol chainsaws, supplied under MPN 1146 162 7900. It is a compact, coiled spring made from tempered spring steel with a protective finish, designed to provide consistent pulling force in the relevant mechanism specified by Stihl for these models. The spring helps maintain correct tension so controls and linked parts return reliably after operation, supporting smooth running and safe function. Its precise dimensions and formed eyelets ensure a clean, repeatable fit in the intended mounting points. Suitable for light professional and domestic saws, including the Stihl MS 150 C and MS 150 TC, it is an ideal replacement when the original spring has weakened, deformed, or been lost during servicing.
