Stihl Farm Boss 029 Chain Binding Problem

[Lakeside53]

a nice thank you... but you should pay the shipping either way.

BTW, even if you put the washer behind the clutch drum (no one would) you can't get the circlip on..

Only if you use the wrong washer. The factory washer has a curved rim.

Perhaps fbcoach has a digital cam available so we can see what the problem is

FYI the first 029s up here came with SPURS and a spur uses what washer mate?

FBCOACH - One other thought... if you didn't locate the oil pump drive arm in the clutch drum correctly, it may have been forced into the oil pump. Even if you did, the oil pump or arm may have been damaged by the prior sprocket/needle bearing. The 029 usually has a large diameter bearing, and it it fails (rarely), the drum becomes so eccentric that the arm is driven into the pump - usually slicing into the pump body and destroying it.

Take off you sprocket, and look for the pump arm (should be undamaged and rotate smoothly) and damage to the pump; you can see the area of interest to the lower right of the clutch.

Same as they do now - 33mm washer. They still have "spurs", athough we don't call them that.

If they are converted to rim, the washer size changes to 27mm, but the roll is still the same.

I am having trouble with my Stihl 029 Farm Boss. Recently I had a sprocket break and the needle bearing went bad as well. I replaced the sprocket and needle bearing. When using the saw now I am having trouble with the chain binding up on me. Regardless of how I adjust it, it ends up getting very tight and binds up. Sometimes it is loose and then it gets tight. It appears that it is damaging the bar by getting it pretty hot.

Can anyone tell me what might be wrong? Is this a clutch issue? Did I put it back together wrong? Is it a sprocket issue?

Thanks in advance.

Sounds like you put on the wrong pitch sprocket there. That would cause the drivers to bind up and tighten the chain everytime it hangs up on the sprocket tooth. Check your sprocket pitch verses your chain pitch, most
029's were shipped .325 pitch but there are many 3/8's out there as well..

Okay big mouth.....I'll have it shipped to me..I will video opening the box and If I am right you pay the shipping both ways....If you are right I fix his saw free and ship it back on my dime and the dealer that screwed up if he did gets the egg...what do you want if you are right?

Pest hate to burst your bubble but Lake is far from a big mouth though you seem to be sticking your foot in yours quiet abit there. Looks like your determind to win the argument at all cost so pay for it. The day you out smart ole Lakeside is the day the ocean runs dry,wink!!!!

Only one question from me...Did you take the clutch off or just the sprocket ???

Well from what I read the man just changed the sprocket and bearing. He never said he took the clutch off so that big spacer washer behind it hasn't been moved. The washer on front of the sprocket that goes behind the clip surely he didn't put it behind the sprocket, too simple. He claims he's using the saw so he got the sprocket back on and all the sudden has a binding problem. That means something has changed all the sudden and its probly the pitch of that sprocket.

If Pest is right I'll give him his dues, no worry on that.

The reason for my guess is based on past experience on this saw. Not all the 029s here have the dished washer holding the sprocket. I understand that there is a chance that the dealer gave him the wrong sprocket but there is little detail on how he conversed with the dealer and how the dealer would have chosen the drum/sprocket. I simply threw out another alternative in hopes that the owner would not return to the dealer with the drum and or sprocket and accuse his local dealer of not knowing what he is doing. I have been on the receiveing end of that scenario. I may have indeed stuck my foot in it..and will indeed give credit where it is due if I am wrong. The reason for my guess is that it appears he has run the saw for a bit and if he is able to change the drum and needle bearing I would think he would notice that as he turned the chain with the side cover off it would try to jump the sprocket. I admit when I am wrong as fast as I am aware that I am.

As far as Stihl no longer calling spur sprockets what they were always called

Also the early 029s here were NOT the larger OD outside washer I don't care WHAT the CD ROM set says

Well Pest I see your reasoning there, thats more like it. No need to take it to the limit with name calling. Glad ya calmed down. As for the binding problem its not life or death, he'll get it figured out and if your right I'll be the first to say Pest you was right. If I was right I'll be the first to say Pest I was right, isn't that big a deal. Good post Pest..
