Im finally getting together a list of parts I need for my husky 444se. I need a new piston for sure and ideally a new cylinder would be a fantastic find but we will see how it goes. Right now I haven't had any luck in finding parts so far. I was looking through the parts manuals I have and have a few questions about the piston part numbers. In the IPL it lists 3 different piston numbers and only one cylinder. i lists them as follows:
501 66 21-02(A-B)
501 6621-03(C)
501 66 21-04(D-E)
My 444 is a 1979 model and the year specific IPL doesnt explain what these letters mean. Later I cleaned the top of the original piston and found a B stamped on top. I think this means to use 501 66 21-02 piston. Any knowledge or advice on this would be greatly appreciated along with any leads as to where I might find 444 parts. I will post some pics shortly.
