Question about Garden
I have a Poulan Pro PP4218AVX, and I watched one of my employees take it apart to clean it, and the rod/bolt that holds the sprocket piece onto the rest of the clutch just sheared off. It looks like the end of the rod just broke off clean, and it was not my employee who did anything with any force to cause this. It just basically fell off. I have another Poulan Pro for parts, but I can't figure out how to remove that rod and install it on the other saw. I figured out everything there is to know about removing the clutch and replacing it, but the rest of the clutch here is fine, and there is very little information about whether or not you can replace that rod/bolt.
Sorry but from what I am seeing and reading, the clutch screws onto the crankshaft then the clutch drum slides onto the crankshaft and an E clip holds it in place... if that rod is broken this means your crankshaft is broken meaning throw it away

my name is Dennis Gladx and I can assist you with the problem of getting the sprocket off of the crankshaft of your chainsaw.
To remove the centrifugal clutch and sprocket you unscrew it from the crankshaft and it has a left hand thread. Also a little trick to remove anything from a crankshaft that could turn while you want to unscrew the item, Remove the spark plug and insert some rope into the cylinder for the piston to squeeze against and you will jam the piston without damage.
Glad to be of assistance Please rate this solution because I can learn from your rating. Thank you

SOURCE: Poulan Pro Clutch Removal
Yes there is a special tool to engage on the clutch. You can get it from the Poulan web site - I think it is part number 31112 - cost about $5. Maybe you can get by without it, by using a screwdriver and hammer, but the tool was easy and risk free. You also have to stop the piston, as the previous poster said. I Googled how to do this, and the consensus seemed to be that it's easiest to stick rope down inside the cylinder, avoiding pusing it through the exhaust port. That worked like a charm. I used a hammer to hit a wrench on the clutch tool to break it loose.
Many thanks to the original answerer for getting me on the track to solving this.

Its almost certainly made by Poulan.
This may help you find an IPL at Sears, they are available:
This lists all Poulans. It will be difficult to find your saw but it is here:
It sounds as though the starter spring is broken.
This thread explains how to reinstall the spring.
The IPL for your saw shows all the parts and provides an idea of how they fit together. GL

Find the model of your saw and open the IPL and handle assembly drawing here:
This is as good as fuel routing gets!!! If this isn't sufficient Find your nearest Poulan repair facility or try your friendly neighborhood chainsaw seller/mechanic. Resubmitting this question won't get any better answer. HTH

Outboard drums (drums on the outside of the clutch) are held on by a nut or e-clip.
Inboard drums are held on by the clutch which is threaded onto the crankshaft. And there is the challange.
***NOTE all chain saw clutches have LEFT hand threads, so, rightey loosey, lefty tightey. (just backwards from everything else)
*** NOTE #2: DO NOT USE AN IMPACT GUN
this will most certainly shear the flywheel key or damage the flywheel !!!!! (after 35 years, you can ask me how I know that, LOL)
1) Use a piston stop to hold piston from moving: THIS IS A MUST !!!
Ok, so you do not have one, let's make one.
a) remove the spark plug
b) insert a piece of recoil rope into the cylinder hole, leaving a tail to remove it by. (rope, large shoe string, anything that is soft, that is aprox 1/4 to 5/16 in diameter to place into the spark plug hole to help the piston to stop it's travel by filling up the empty space. Just make sure you can remove it later)
c) secure the saw (extra set of hands may be needed) and with a suitable wrench on the clutch center, rotate the clutch to the right until piston comes to a stop. With a hammer, tap the wrench to aid in rotation. This can be very difficult, and may take several taps.
d) after removed, inspect and grease the drum bearing before re-assemlby.
e) upon re-assembly of clutch, tighten by hand only, NO hammer required. The force of the chain will tighten the clutch.
f) remove the rope, and re-install the spark plug.
