Description
Overview:
The Crankseal Driver is a genuine Husqvarna service tool designed to install crankshaft oil seals accurately and without damage on selected Husqvarna chainsaws, including the 181 and 288. Made from precision‐machined steel, it provides a stable, square driving surface so the seal seats evenly in the crankcase. This maintains correct alignment and sealing performance, helping to prevent air leaks and premature wear. Engineered for the tolerances of the listed saws, the tool supports routine maintenance, rebuilds, and professional workshop use. Identified as Husqvarna No. 502 50 82 01 (MPN 502508201), it is suitable for users who want a reliable, repeatable way to fit crank seals on compatible machines.

- Genuine Husqvarna OEM tool for assured fit on specified models

- Protects the seal's outer case, lip, and spring during installation

- Husqvarna part reference: 502 50 82 01 (502508201)
