did the rim sprocket come apart or the clutch?

good call, here is the photo

i've got the saw set very rich. i put the tach on it and it was still 4-stroking over 11,500 no load. i didn't try to go farther than that. i backed it off to 11,800 no load and made about 10 cuts before the video. so, i don't think high rpm's was the factor in destroying the clutch. who knows?

 

[homelitejim]

best way to find out is strap another clutch on there and give it hell.

or have an arm jerked out of the socket.

I've sharpened a few chains that I couldn't cut with without re doing them. They were too grabby and would just bog if you didn't hold the saw back. I sharpened the chain on the 125 and it would really pull itself into the wood and I didn't touch the rakers at all. One of my buddies thought you should push on it real hard since it was big. With a good chain setup it will pull you into the wood or pull the wood to you.

Been there,

The IPL shows one or two thin washers (shims) under that center assembly. If it is missing you will tighten it down too far on the taper, CRRack!

The clutch doesn't tighten against any washers.
Just the taper. Iv'e had this happen on a restored
Homelite 3100. My heart dropped but it was an
easy fix.

I dunno,

I broke two on a 7-10, put the spacer in and all is good?????

are you talking about number 23 in the IPL?

I believe that washer is there simply to protect the seal, the clutch drum will still have a little float even with the washer in place so it isn't really limiting the movement of the clutch spider.

I've broken a clutch or two as well, usually from overtightening with an impact wrench.

yup, i like my saws/chain to do the work, . when you have got it right you don't need to leen into it . it's a great thing when you have it right.

Yeah I try to have all my chains do that both round and square filed. The round filed hook makes a big difference in how hard it bites. Maybe when I get time i'll take some pictures and videos of how different chain setups do.

Any idea what model this is? A friend sent me these pics and didn't get the block numbers.

the hub should be beefier if that is happening. like mark said too much, tightening torque streatches it out. impacts can't feel the taper as it snugs up and seats.

Maybe a 44

I did use a impact gun, this is my first broken like this. I bet over tightening is the problem.

Different recoil and fan cover.

 

[cpr]

Definitely not a D-44. Most likely a Super 44A.

 

[heimannm]

Super 44A or Super 55A, only machines I have seen with the hockey mask over the fan cover.

Others have said some Super 44 and the same, I've never seen one like that.

Someone has changed out the original round muffler to the stack.
