MS261 chain break stalling engine

[Stubby]

the work one has loads of new new bearings and a new clutch drum but has worn the crank beyond use. not great for a saw thats about a year old. repair shop said it will be about 400 euro to fit a new crank!!!

 

Not fit for purpose . Contest it . You are one in thousands bud .

Mine was like this. Just out of warranty and Stihl agreed to the rebuild with new crank etc at no cost to me, as it is a known problem.

 

I've got another 261 starting to do the same thing.

 

Get your repair shop to contact stihl.

If the saws are spending most of their life idling with the chain break on sitting beside Chippers or hanging from a harness then this will be the cause of most of the problems imo.

If a saw has a forest life it will rarely get this type of treatment.

id say more to do with a faulty batch of 261,s rather than the type of usage as no other saw that ive used needs a new needle bearing every 2 weeks, obviously the less you use the brake or leave it idling will help but thats not the point.

My 261 is two months old now. Will be checking needle bearings regularly.

Bit worried

Do you use your other saws in the same applications as the 261?

Now that I've changed my ways I don't get the above problems .

This makes some sense in that the saw rarely idles in forestry for long periods. It's only when idling that the needle bearing moves relative to the crank.

 

The bit about the chain brake is intriguing in that it probably exerts an off centre load on the clutch drum which is transmitted to the bearing. I'm afraid I'm from the generation that doesn't apply the chain brake routinely whilst working.

 

 

Also full load stalls will heat up the clutch and potentially melt the bearing plastic cage.

 

We had several MS261s but I only had to deal with 2 with this bearing problem, one was rebuilt under warranty and the other didn't damage the crank but the rim was changed to a sprocket (or vice versa I cannot remember)

[Stephen Blair]

I've always been a die hard chain breaker!

Also since my reduction is staff over the years I do all the chipping with a 26 parked beside me chattering around the ground.

Thanks to Arbtalk I found out my stalling saws were the damaged bearing.

I used to just buy new saws lol

some of the saws would be used in the same way including an ancient ms260 that is on its original needle bearing.

got two echo 501,s now and they seem fine.
