MS261 Clutch/Crank

[Rough Hewn]

Gave back the lightly used 2012 MS261 to the owner, explained that the crank hardened coating was shot, showed him the pitting on the shaft with a magnifying glass and then measured the shaft diameter above the circlip, below it and then near the actual clutch showing a nominal 10mm above the circlip and 9.65mm near the clutch - 0.35mm under nominal is well buggered and uneconomical to repair.
 

Yeah the early versions were crap.

Crankshafts were not properly case hardened, once the bearing ran dry of grease, the heat build up destroyed the very thin case hardening, resulting in the chewed up crankshaft. Stihl trying to save money and cutting corners again! I have replaced a few now, in fact I am doing one at the moment!

I think the operative word ' ran dry of grease '  don't see people greasing sprocket bearing-  was drilled into me on my forestry , but never see it happen now. K

My take is that there is an issue with this model of saw during some part of its history which CAN'T be blamed on lack of grease. I have done enough saws to know that most of the previous models had no issues with needle bearings detonating as I have changed almost none on MS200s, MS460/440s, MS260s, MS660s etc and many were minging wrecks where servicing was a stranger!

Steve, try and be gentle on us.

I have some Husqvarna saws were I am ashamed to say I have never greased the needle rollers and there is a port on the end of the crank shaft for just that .  Its not lack of grease on the 261 .
