8T Rom spline on a 026

[kfons]

I have been trying to put a 8 tooth Rim drive sprocket on my Stihl 026 which currently has a 7 tooth. I purchased the small ID 3/4" but it seems my splines are even smaller than 3/4" Do I need to change the drive / clutch cover to go to a larger spine? I was told by a arborist friend I could just buy the sprocket and swap it out but it doesn't seem to be working for me.

You just need the rim sprocket. part number 0000 642 1234 for .325; 0000 642 1241 for 3/8 picco.

That is what I thought I had but the id is too large - the part number on the drive is 1121-160-2900. I think it may be the mini spile if there is such a thing. I cannot find this part number though anywhere online.
Is there a way to go to a larger RIM to use the Oregon small Rim Sprockets? I have two of those.

the normal Stihl 026 clutch drum takes a mini size sprocket, the Oregon and GB aftermarket takes the larger "Small" spline and has a larger selection of sprockets.

The part number I gave you for the rim is correct... The drum number is not a valid ordering number as the drum is only sold as a kit including the rim washer and clip.

You cannot use the larger internal size sprockets on the Stihl 026 drum.
