I think I know what’s been happening. You’ve been using a 660/661 with standard 3/8 chain for years. That’s a medium torque power head with a strong chain. You’ve upgraded to a high torque (881) power head, and downgraded the strength of your chain (3/8LP) Gone from 36” to 48”, Used the wrong file size And you’re using a winch which massively reduces feedback. Then you mill like you have done for years... And it goes horribly wrong... Sprockets pop and chain snaps. And you’re 100% certain it’s the kit?

60” stihl bar? Nice rig [emoji108][emoji108][emoji108]

A stihl msa200 or similar [emoji106][emoji106][emoji106]

Mill it and post some photos [emoji106]

Any close ups of the chain and rim sprocket? [emoji106]
-
Lots of photos of the damaged kit would help diagnose the issue as well[emoji106]

Ah shame it’s such small pieces. That’s pretty worthless I’m afraid.

Not at all. The guy who runs Chainsawbars is one of the most experienced millers in the UK.

What diameter? Any photos? Very large MP is saleable. [emoji106]

Didn’t want to give it back...[emoji22] [emoji106]

Testing the pre production Stihl ms881. Got it mid March for a couple of weeks...... Handed it back end of July. Thank you Boris. [emoji106]

That only pays wages.

Milling is really tough on all your kit. Also it’s a balance between the slightest of pressure and wrestling a mechanical lightsaber. Stihl only recommend .404 on the 8 series. Might be fir a reason. [emoji106]

That’s a log goblin! 🤣[emoji106]

Can you see the butterfly wing in 5th? [emoji106]

I’ve destroyed 2 x 56” .404 chains and a rim sprocket in the last fortnight. And melted the 880 engine recently. All user errors. (And inclusions). Just saying. [emoji106]

Few more pics [emoji106]

And this is it ripping through 36”-50” olive ash. It’s was very bitey🤣[emoji106]

Chain testing with the stihl ms881 today. With the big mill, 80” panther horizon, 84” GB bar. And today’s chain is the Oregon semi chisel FULL COMP .404 [emoji106]

Interesting. Personally I only use .404 with 880&881 and 3/8 on the 661 and 461 Never broken a chain, and I push them hard. Not used 3/8LP , but if you’re having issues like chains snapping, I would take my kit apart and have a serious look as to why. Do you have any photos of where the chain has failed? Blowing noses is often due to excessive grit/sand etc, or when the chain is hot and gets retensioned then left to cool. The rivets stretch. This causes excessive play in the links and grinds away. Do you use one file size? The height of the cutting teeth diminishes over the length. I drop a file size halfway down the tooth to avoid excessive wear to the tops of the drive links. How’s the sprocket looking? [emoji106]

What’s been your experience? [emoji106]

You’ve got a 42” max cut, You could just trim each side a little? [emoji106]

Fair play mate, looks legit to me [emoji108] 🤣🤣🤣🤣[emoji106]

You’ve got a milling license? Got a photo? [emoji6][emoji106]
