Spur v Rim for 261

[thetoolnut]

I have a 261 (2013) with a rim sprocket and a 241 (2014) with a spur sprocket. Given all the trouble lads have had with their 261's which seem to be attributed to rim sprockets, would it make sense to head off any future problems by swapping the drive sprockets around? What do ye think lads?

Better change to rim o the 241 as well, when it is time for a change (wear).

 

I highly doubt the MS261 troubles have anything to do with the type of drum/sprocket!

The troubles with rapid wear on MS261 crankshafts have all been attributed (as far as I am aware) to the clutch drums with rim sprockets. Spur sprocket drums appear not to have any issues that I have heard of.

Not surprising, as a spur sprocket on a 261 would be a rarity.

We had two 261's , I think it was about 2010 . Both had various bearings , clutch drums and one had a new crank . The dealer converted both to spur sprockets in the end .

We didn't keep them too long after but both were still going trouble free when we sold them.

Mine both got changed to spur sprockets from stihl dealer and they aren't any better

I think from memory ours ended up on Oregon bearings ? Steel cage type . Maybe that made a difference .

More than probable, the glass fibre ones degrade very quickly!

Thanks for the input lads, i might be robbing Peter to pay Paul so. I'm fairly anal about greasing up the needle bearings every second Day or so. I use Oregon red liquid grease, it's great stuff.

Never greased a needle bearing in all my life! Never had a problem
