Look,you need basically few parts and one small set of parts to complete the switch .I'm going on 51 and am determined to avoid glasses. I get annoyed at even wearing saftey glasses....lol!
Since you mention the thumbwheel, I'm kinda disliking myself. I got to messing around with my 180c last night (hadn't really messed with it before) and that adjuster was bothersome with my sore thumb. I can't imagine what it'd be like to fiddle with it and cold hands in the winter. I haven't the money for a bit to switch both of these Stihls to normal adjusters, so the 180c will just have ride with it for a while.
1) A bar stud OEM or aftermarket .
Here in Greece an aftermarket one costs about 2.5€ ,
while the OEM Stihl costs about double .
OEM Part S/N : 1123 664 2400
Unscrew the Torx bolt ,with its nut
all the way down install the stud in place .
2 ) Bar nut ( get more than one,trust me ...) OEM or AM .
Costs less than the stud .
OEM part S/N : 0000 955 0801
3 ) Side cover ,
AM costs about 15€ here.
O.E.M.# 1123 640 1705
