261 clutch drum bearing.

[Stubby]

took it back to the dealers and got the needle bearing fixed, they said that was the problem, hopefully it will start behaving itself .

thanks for your help.

Yea but you got to baby it . Grease it every day . I got a Husky 372 that's 10 years old and never greased it at all !

everyday god! not even a proper grease point on it like on the huskyies.

Yeh we grease ours every 2 days and it still keeps happening. Stilh do replace ours though when they do go as its a common problem.

 

Hopefully it won't be a problem for too long though as we've just got a 550 and 560!

Make sure it has a spur sprocket not a rim, its the rim type that can cause the trouble

Guess Stihl expect us to take the C clip and clutch off for maintenance all the time..never understood why they don't put a grease hole in the shaft like Husqvarna !!

Can you elaborate on the Rim V spur issue ?

[stihlmadasever]

Is this needle bearing issue on the newer saws,ive got a 2012 261,with a spur sprocket and never had any problems

[carlos]

ours is 2015 and has a rim sprocket and the needle bearing has gone in next to no time,

The cause of the bearing failures is generally down to an egg shaped centre hole in a few sprockets. If the operator carries on using the saw without spotting the bearing failure , the crank will become scored and need replacing as it will continue to chew up bearings. The egg shaped hole was only found in rim sprockets so we replace all rim sprockets with spur sprockets , even from new, spurs havent been known to cause any issues. This only applies to the MS261
