8 tooth 2186

[Tony Snyder]

If you've ever wondered how well a stock 2186/385 will pull an eight tooth rim in hardwood, I tried it today. The answer is, not worth a hoot. It pulls it totally out of its power band and it falls on its face. Amazing what one tooth will do.
(14 % higher gearing)

That's interesting. Was this saw modified at all? I feel the 046 runs better with an 8 tooth in hardwood.

I picked up my 046 yesterday and before I left asked the owner of the shop his opinion about putting an 8 tooth sprocket on it. He told me to leave it alone. Any time I ask him any questions about adding/modifying parts, he stresses to leave it alone. Could that be so he's not liable for my mistakes, or maybe so I don't void my factory warranty?

By adding another tooth, what is the benefit? More torque? More speed?

I would reason a larger sprocket would tend to decrease the torque(powerhead torque would be the same but diminish quicker with increased fps chain drag)but increase chain speed.

Perhaps a shorter bar and/or smaller kerf chain would be beneficial,if it does not defeat the owners intended use for the saw.

What is the depth guide/ raker clearance on the chain you are using. Unless you are coming down hard on it I would think a saw tha size should swing an 8 tooth judging by my 365 Husky.

I run my MS460 with an 8 tooth and a 20'' bar and it cuts ALOT better that way in hardwood.

Thats the first thing i do when i get a new saw, put an 8 tooth on. been using them on my saws for 24 years and aint complaining yet.

I ran my newest Shindaiwa 757 the other day. The saw has an 8 tooth sprocket, and a 24" bar running full comp./full chisel chain. I had a hard time stopping this saw nose buried in hardwood. This saw for sure isn't a speed demon but the bottom end torque more than makes up for it.

 

[Tony Snyder]

I have tried 8 tooth sprockets in the past also, some times it helped a little sometimes it didn't. It didn't work in this case.

It was new Windsor chain cutting a one year off the stump Ash log with a 24" bar.

Hello Tony
Lighting strikes the same place twice.Has that hardwood been sitting in front of the saw shop for 3 years. We had 2 demonstrator 2186's in March/April after the 2 460's pistons failed. I mostly buck at the yard or landings(only because the fallers think I am a crazy falker with a 044HB that will rock their new 066's). I love the 2186 and so do the lead guys with a 7 at the stump but 8 at the yard. But in Wisconsin a 28" bar is long. Seth

 

[Tony Snyder]

Not 3 years, but ya, its a hard one. The 2186 just fell on its face with the 8 tooth. I put the 7 back on and it straightened right up. The saw had had the back handle / tank unit smashed and repaired by me. It is also possible there is another factor that I have not learned of as yet. I am waiting for feedback from the owner. He has other 2186s, so I'm sure there will be some side by side trials.

I run an 8T with 24" 3/8" on my 111S with no sweat, but then again, I could probably run a 10T.

Hi Tony, I`m also a little curious to know how this saw stacks up against the guy`s other 2186s. The 2186/385 doesn`t seem to be the strongest saw in it`s class in stock form, but you are describing weaker performance than I have seen.

Remember, how the chain is sharpened, hook angle and raker height, will affect how much power it takes to pull.

Not that I'm comparing apples to apples, but...

When I switched to an 8 tooth sproket on my 385 G, I noticed that the raker depth made a big diiference. I've been running an 8 with a 32 "bar lately and I can't complain. I think if I went bigger, I'd switch back to the 7. The 8 with a 20" bar cuts like a beaver on crack.

 

[Tony Snyder]

This is a hard Ash log. There may also be some as yet undiscovered issues from the damage; That is I may not have found everything. If it does not measure up to its sister 2186s, I will hear about it.

 

[Stumper]

Interesting. I just dug up this thread while doing a search. I'm surprised that a 2186 would stumble over an 8 pin. I'm running an 8 on a Husky 268 w/24 inch bar-nooo problem! I do run skip chain on everything 20" and over.

 

[sawyer40]

I'm going to experiment with a 9 tooth .325 sprocket that is the same size circumference as the 8 tooth 3/8 drive sprocket using a 16" bar on an 044 i'm setting it up to cut pine 8x8. Here we go any comments or opinions?

 

[Jacob J.]

<p>Hi Sawyer<p/>
<p>I run a 9-tooth .325 on a hopped-up 044 with a 24" bar no problem. I even run standard sequence Stihl 23RS chain and it just keeps pulling and pulling.<p/>

 

[Tony Snyder]

Some of the differences that are getting mixed in here pertain to the hardness of the wood being cut. Just look at the addresses.

All I claimed in my original post was that in my particular circumstance an 8 tooth pulled the saw out of its comfortable power band. New chain, about year old Ash.

Also keep in mind that a loggers expectation of performance is different from most amatures.
