I have a Stihl ms261 C-M (mTronic) that is just plain stock with an 18" Rollomatic E bar and green labeled chain (I believe that is RM3). So the current specs are:
Bar type: Rollomatic E
Bar length: 18"
Bar pitch: 0.325"
Nose sprocket: 11 tooth
Bar groove: 1.6mm / 0.063"
Chain pitch: 0.325"
Chain type: RM3
Chain drive link gauge: 1.6mm / 0.063"
Chain drive sprocket: 7-tooth, 0.325" rim sprocket
I want to swap out for a Light 04 bar which I believe uses a 1.3mm gauge chain.
If I get a Light 04 and 1.3mm gauge 0.325" pitch chain, do I need to change anything else? Will my drive sprocket be compatible with the new bar & chain? I want to stay with 18" length, if anyone could confirm part numbers for the new bar and chain that would be greatly appreciated.
