Bar binding in cut.

I want a second chain. I gotta pit in an order somewhere just not now. I will toss it on the grinder and see what I get.

 

This is a saw I rarely use. I only have one chain. I can hand file but choose not to.

I have maybe 10 loops for 20" as that is what I use most on the 372,390,650. I take 2 of those saws and about 4 loops when I go to woods. I just swap them out. I grind at the house. I get uses chains usually from logger buddies after their guys file them 3 times or so there so jacked up they take im off. I grind them back to specs and take the rakers down and run till their triangles. I usually run 3 tanks of fuel or so before I swap loops.

 

Unless I am seeing the picture wrong, the rakers look too low on some cutters ............. and those cutters do look dull.

Is looks like it could be too grabby and stopping due to the low rakers - any way of getting a picture of the whole chain on the bar from the side so the rakers are clear ?

 

Yea I will get a whole pic.

But of the raker were too low and it were grabby the chain would be STOPPING in the cut...its not..the forward progression STOPs and the chain KEEPS SPINNING but not cutting.

I will get more pics. But it may be a few days tilliI can sharpen and retest unless I stop by a saw shop on my way if I have to go into town.

 

Ok since were all so involved...here I am grind I chains at almost 10pm!!

For those who asked the rakers are close enough to .030 for government work. But seriously they are just below the .030 mark on my gauge.

A pic of the chain as it came off the saw tonight.

I will blow the saw off as well and get all the crud out of it.

 

I looked around. Couldnt find a file small enough to hand sharpen. I had one bit not sure where it went??

I did grind it. And I can tell it helped it hopefully thats the problem??

Although I will say this...I hate to admit but I have cut plenty with chains way way duller than this years ago. And I never had anything g like this happen. But this is really the first saw I have uses much under 60cc so maybe its a small saw thing??

And I looked in my stash. The only other 14" chain I have is a 52dl chain in oregon vlx or whatever out is...for the earthquake. Stihl 14" on this bar takes 51dl.




A terrible pic but I worked to get this one. Of the ground cutters

 

I will try and remember to take the saw both bars the fresh ground chain and some feul and oil with me to work tomorrow and stop by a log at one of my logging jobs and make some cuts in say 12" stuff and 8" stuff and see what I have.

If I have too I might have to do what I said I wouldnt do and stop by the sorry excuse for a saw shop in the close town and see if they have a chain. I got mad at that place when they took over 2 weeks to order a carb kit. Should of just got it somewhere else....live n learn.

 

If the problem is a dull chain, it's not the fact that it's extremely dull, It's that it is dull on one side. That makes it cut crooked (circles) to the point that the bar can't follow the kerf, this causes the the bar to bind in the wood which tries to force the chain off the side of the bar. The side of the chain is trying to cut. And the drive links to bind in the groove. Makes for lots of heat/smoke/wear. Think of starting with a straight cut then trying to turn hard half way through the log, same concept.

Tall teeth on one side of the chain or uneven bar wear can do the same thing.

 

Yea I know trying to cut circles will bind it up. But I have some chains that I have all out of whack and they try to cut circles, but still cut. For this one to be that bad on a chain that was brand new...even if its getting dull now I find hard to swallow? I have not rocked this chain or put it in the dirt for even a split second that I can remember? I almost never hit dirt, and this ssw cuts trees that I can totally pick up usually so its not like I'm cutting them laying on the ground. I lay them on other branches or cut them by lifting with my foot if I even turn the tiny things Into firewood. Most trees are dragged into the woods off a road or field edge.

Anything g is possible though..I guess I should never say never. Watch y'all all be right and me look like a total idiot

 

Could have been a factory defect. I bet it cuts fine now but time will tell.

I went through a lot of cutting circles/binding chains learning how to hand file. I can't do anything left handed and it took a while to learn to sharpen both sides evenly with one hand.

 

I don't understand your explanation of the problem. The chain is "spinning" but not "cutting"... ?? Sounds like it has no bite, loose chain, rakers set high, wrong gauge for the bar, I guess what everyone else said.

"Forward progression" ?? This isn't football man, what do you mean by that?

 

Point blank - ya got a dull chain. Might not feel like it or look like it but that's what it is.

 

the chain is still spinning. That means what I say, dont know how else to describe it.

The bar/chain stops moving through the cut.

I sharpened the chain. If that was the issue I look like an idiot...if not I will make a video.

And if problem persists the chain was bad out of the box cause I have not hit anything to make it cut major crooked like this. I will try and buy another.

 

Ok I'm the idiot and y'all deserve all the credit.

I knew the chain could use a sharpening but was telling myself that sharpness was not the issue. I was suspect somewhat of the chain since the problem followed the bar. But have never had a chain that was dull cause that kind of problem?? It was just as a chain with one really sharp side or side with raker too low or a mushroomed bar rail. The bar just stopped in the cut. NEVER had a dull chain keep spinning as the bar would no longer go through a log?

I did test cut in pine when a hardwood was where the issue showed up. I need to find a hunk or hardwood to test now.

Should of just listened to everyone. As the wife says mr hard head. You learn something new everyday. Lesson....a chain that you have not rocked or abused or cut into the dirt with can end up with one side totally shot and pull so bad it binds you bar up???!!!

 

And cut in a sweet gum about 8"s and not weird binding issue.

I apologize I am the idiot!

 

This saw only has one nut and stud

 

The bar mounts to the stud, the nut's behind it

 

Yep your right. Stud pressed into crank case and then bar, clutch cover and nut snugs it all up.

Believe it or not I have even replaced a few on afew husky saws

 

Don't feel like the lone ranger. This summer I was havin a fuel problem with my 1750 Oliver. I spent several hours and some money replacing fuel lines, sediment bowl, fuel filters just tryin to track down the problem before I would've spent more money and time on a carb rebuild. Had old Ollie runnin good in the shop when I got done. Took the tractor out to do some brush hoggin and after an hour the dammed thing started acting up again. Same problem as before, like it was starving for gas. Managed to limp back to the shed just barely to see what was up. Took a look around the tractor and seen the sediment bowl was only half full of gas. Grabbed a flash light and a step ladder and looked in the tank. Bone freakin dry. Fuel gage was reading wrong and I ran it outta gas. I guess my point is that sometimes we over look the simple things don't we?
