Rubber piston stop?

[Chris J.]

I only take the clutch and/or flywheel off a saw if I absolutely have to. The other night I spent nearly an hour trying to get the clutch nut to break free, but then I noticed that the little arrow was pointing counter-clockwise (that's a joke, I'm not that dense, and I've read just about all of the posts on removing the clutch). Someone told me that the shop they use uses a rubber piston stop and an impact wrench. I'm not clear if it's an actual piston stop, or something the shop rigged.

I'd certainly appreciate your advice and thoughts. An incentive: If I get some good advice I'll tell you about the really stupid thing that I did.

on the ms 200's i just put an air gun on it and zip it off with out even removing the plug. in the bigger huskies i pull the plug and fill the cyl with 6mm cord and use a ratchet and socket. on the 372's with the funky clutch i have a 4 wheel drive socket i ground down to catch the cluth. i just ordered a piston stop from madsens yesterday.

I agree with KF on the rope, I use an old sparkplug with the guts broke out and a 1/4" rubber headed bolt welded on. This was before i got a lathe, now i would turn one from alum bar stock...Bob

I mostly use the rope trick, but sometimes I run them off with the airwrench (is that correct word?).

I was using a socket and wrench on a very stubborn Jred 670 parts saw. I started off using a piece of old spark plug wire in through the plug whole, but it eventually started giving and letting the piston move. I couldn't find my thick spark plug wire, so I went with the thick end of a punch, which I would not have done except the J & P on the parts saw are trashed.

Crazy part is I got seriously POd , and was considering the Benz-O-Matic and a 4# hammer. Instead I took a break, and when I came back the d@mn thing broke free on my first try. And when I went to my good saw the spark plug wire worked just fine, and the nut broke free on the fourth try. So maybe it all balanced out.

Is there an idiot-proof way to get the nut off of the clutch?

I use pull cord rope, I melt the frayed ends with a lighter and it works great... I was changing the clutch on a Makita DCS 400 once. The arrow pointed counter clockwise (I thought it was strange) well any ways out with the impact gun and I whipped it off counter clockwise.. When I got the nut off it was stripped luckily the crank had no damage.. Ever since then I use the rope trick on all saws. I thought it was stupid that the nut had an arrow on it pointing counter clockwise (would make ya think that was the way it was supposed to come off)...

Clutch removal

Chris , I use a woven cotton rope , breaker bar , and a clutch adapter socket . Here is a thread that you might find interesting http://www.arboristsite.com/showthread.php?t=18726

I caught a mistake in my orignal post, it's funny, but it was unintential. The nut is clearly marked TURN with an arrow pointing clockwise, not counter clockwise.

Thanks for the tips, & please keep them coming! Maybe tomorrow I'll reveal my goof; it's a good one.

Use a rope and a torque wrench or an impact gun (a strong one) but dont put the nut back on with it because you probly will strip it.
