Chainsaw Repair

Uses 1.2mm rings like the 660.  Also can see it beside a meteor 066 piston pin to pin.  66 just a hair taller but skirts just a hair shorter. Plus the pin bosses on 66 narrower and need opened.

Weights of both bare, 2 ring and 1 ring

Roger you can see how off that 52mm that was sold for 475 2077 is off. Pin bosses were right though as in wider as they should be for use.   I am betting they modeled that piston off a 046 460 which is just a miss.  They should have used the stihl 064 650 piston for the 475 2077 2083II 52mm
