Tricky sprocket...

[sickamore slim]

Need some Help!!!
i want to change the sprocket on my 044 stihl from a 7 to an 8 tooth. simple right???? Not so in this case...
I CAN NOT GET THE CLIP OFF!!!! The c-clip is recessed down flush with the washer. It MOVES AROUND &
AROUND and I can not get to lift up any to slip it off. I have tried filing down 2 screw drivers to fit into the 2 small notches in clip,
I have tried to push, pull, pry, and even made a special small 90 degree pry tool from a paint can opener that fit nicely in the 2 notches in the clip. Tapped, pecked,pushed, pried,pulled... no cigar!!! clip now broke it 2 pieces. ANY IDEAS??? I have only been cuttin for about 40 years now ,so I am still a student and always ready to learn. Help me if you can,please and thank you.

sounds like you just need some new clips if I understand you right. Somtimes they just get stuck.

yep and a set of circlip Pliers to get them off with, I always carrie a few around in my tool box as back up.

sounds like that clip is on back to front

I had a piece of trash get stuck behind the washer and it pushed it out to the clip. Did the same thing your talking about. Had to pick out the junk so the washer would float down on the shaft and get room to pop off clip. :msp_unsure:

I use the orange handle tuning screw driver to get um off no probs.

A lot of the time this is caused by crap being stuck behind the clutch cover... it builds up and pushes the clutch out, which pushes on the washer and then the clip. This is especially the case with the more modern washer design which has a recess. The old style was flat. The way to get them off typically is to start with the chain brake off. You'll never get it moved with the brake on. Then give the whole clutch a good whack inwards. I sometimes find that just using a scrench with the driver part resting on the clutch and using the palm of your hand to give it a whack is enough, but you may need to use a small rubber mallet. Go easy, there are bearings in there.

Then, with the brake still off, get to prying. You've got the right idea with filed down screwdrivers etc.

Sounds like it is not setting on the oil pump driver spring correctly.

I know what your saying. Out of many Stihls I've had my hands on, my 460 is like that. It appears to have a thicker recessed washer that any others I've seen. I've removed many, my 460 is the only one that gave me fits. If I remember... I destroyed the clip and used a new one.
Even with snap ring pliers (which I have) it's almost impossible to save the clip.
The problem is... the recessed area does not have a large enough opening to fully open the clip with pliers. The clip can be fully opened and the ears are still in the slot and the outside of the clip is hitting the "walls" of the recessed area.
If I remember, mine had a machined looking washer verses a stamped one. On a machined one, if you used a dremel and made the recessed area of the washer a hair larger, the clip would be able to fully open.

I don't know where in IL. you are, but if your near Essex.... bring it over.

Arrow....

Would you post a pic of your 460 and this clip problem? Sounds like others haven't see this either. Might help the OP too.

Sure, I'll do it later today. I've removed possibly hundreds, only this one particular 460 gave me fits.

Yes, I have seen it before, now that you mention it. It is the thick washer that has a steep bevel that will not allow the e-ring to come up and
off.

The mediacat shows 2 different washers, depending on whether it is a rim or spur sprocket, you might want to get the other washer for next time, one is 27mm, the other is 33mm.

Exactly. You explained it in far less words than me.

Yep, those ones can be a real pain!:censored:

What you're dealing with is a machined washer, rather than a stamped one. The recess is deeper with sharp corners. It can be difficult to remove the clip. You should be able to get it done with a tuning screw driver. When reinstalling, put the sharp side of the clip to the outside.

Reply to e-clip problem

Howdy fellas. Sickamore Slim here with a Great Big "Thank ya" each one of youto all of you for you wise comments and advice. It appears that each one of you put a piece in my puzzle. I finally had victory and got the clip off. Here is how I did it... 1) the washer was recessed with the e-clip in the recess and holding tightly~Mighty Tight around the barring with Absolutely no room around the recess for e-clip to be pushed free of the barring. The clutch had Absolutely NO up and down travel. All parts clutch,barring,washer,and e-clip moved freely as they should but Absolutely fast tight up and down. Almost as if they were of one unit made together but rotated freely as they were designed to do. That in a nut shell was what I was dealing with.
2) I rechecked for any small bit of crap underneath the clutch by blowing 120 lb pressure around area. I found nothing to hamper it.
3) Tapped the clutch lightly with mallet. Again no cigar.
4) Ground thin putty knife to a little bit thicker than a sheet of paper and tried to insert under the washer beneath the washer and top
of clutch. There was absolutely no give. Clutch would not depress and washer would not raise.
5) Took a very tiny chisel and tapped down on the e-clip and recess area of washer breaking it in two. Both washer and e-clip were now broken. I was then able to pick out the pieces and free the sprocket!!!!
7) Replaced sprocket,washer,and e-clip. But still no up and down travel on clutch... Put on bar&chain it ran great for a few minutes
then the chain came off. I took it apart and the e-clip broken/gone.washer broken/gone/ bearing broken...
8) I retrieved one of my old 460's and low and behold it had the travel up and down or in and out depending on how you are looking at it
9) I removed the e-clip with ease probably 30 seconds! Clutch went down (or in) washer followed suite exposing e-clip for removal
PIECE OF CAKE!!!
10) I re installed that clutch from from my old saw on the 044 in less that 2 minutes tops. There was up and down or in and out travel to allow me to install e-clip with ease. Then assemble bar and chain adjust tension on my chain and I am ready to go.
I think that the washer was too thick. Although I did not see any junk/crap under it is still possible.
I say thank you to all for your advise. With your wisdom the problem was solved. Sickamore Slim

I just came across a 461 with thick washer. I broke the clip to disassemble. I'll be looking for better parts when I put it back together, or maybe correcting the factory errors by grinding. Unbelievable mess for something that was so good and simple for so many years......
