Honestly I don't know why that seems to happen with the Huskys. Maybe they have tighter tolerances so they bind up easier?

Does it do it on a new drum/needle bearing?

It might just be what you're cutting, which you alluded to, as I've not noticed dust/debris on the shaft of any of my outboards.

 

[davidwyby]

I will have to pull them down and compare carefully

It's probably not the drum/bearing or shaft, but nice to rule it out.

yes, bearing. Cleaning and lubing it, or just dripping oil down into it frees it up.

Are the needles all there and in good shape/position? Metal looking worn on the edges of the cage itself?

Dave, I'm not expert by any means. But I think a rim sprocket with radial ports on the one side would help out in your situation on the Jonsered. The sprocket side with open ports should face outward. It would use centrifugal force to throw out chips and dust and prevent packing material into the clutch drum bearing. Your powermate may have these oval ports. Can you turn your rim over to see? I would look at this first. If not get a Powermate with radial ports on one side and mount them outward. Hope this helps. Worth a try sir.

This is a radial ported rim. The ports would face outward against your washer.

I’ve cut a lot of Euch…back in Cali…both green and dry like your stuff. The older red gum is the worse. When green it cuts like butter…5yrs dry, not so much. The problem is the high oil content in the wood. It can seize up bar tips just like clutch bearings. I always wondered about carrying a CO2 tank to blow saws out when in the field to keep the dust down during a full day of cutting.
Good luck

Crappy Husky air filters I tell You...

Dust getting in everywhere.

 

[davidwyby]

I think the answer is the closer fitting stihl washer and the plastic bearing cage acting like a seal.

I wonder if Stihl makes a bearing that would fit the Husky. Fewer needles makes more sense to me to keep things cleaner.

I use a 3/8 air ratchet. It won't over torque it. My saw shop here I watch them do it one year and learned that, became my method too. .404 is my preference, if my saws were not mostly setup for 3/8 and the cost to switch over. I would exclusively run .404.. I always liked the external clutch.. Only downfall a timber faller.friend taught me, if it gets hung up on a tree it's a bugger to pull the powered. I told him I never had an issue, then a week later I git my 395 hung up, had to pull the powerhead and saw what he meant. I still think they are a great design and like you said disperse heat well.

That's wild. How many hours of cutting before this happens?

 

[qurotro]

But I really hate the Stihl's very tight and thick washer. I've come across 2 that binded up with the clutch drum and the crank slot that fit the E clip would wear out eventually cause the crank E clip slot nolonger holding a E clip anymore.

Not many at all. Couple big oaks with the 2188
