Broken crankshaft on Poulan PP4218AVX Chainsaw

As I was gently taking apart my chainsaw for cleaning today, the end of my crankshaft holding the sprocket for the clutch on just fell off. The end of the shaft just sheared off very neatly, so I looked up all the instructions on how to swap out the clutch since I already have another Poulan saw I can use for parts. I got the clutch off the parts saw only to realize that crankshaft is on there pretty good. Is there any easy way to remove the shaft from the broken/parts saw and put it on the other saw? I know everything there is to know about how to remove/replace all the clutch parts. I just need to know if it's possible to take out the crankshaft and swap it out with the other saw.

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.

SOURCE: lost my manual for my poulan pro 255 chainsaw the

If looking for parts your OM is of little value. You can find an IPL (exploded parts list) here (only one PP255 listed):
Rear vibration (isolation spring)s appear to be item 5 or 59 on the "Exterior Assembly" print.

Poulan replacement OM.

There is contact us number in the OM if you want to contact Poulan. HTH

I need to replace the bolt/rod holding the sprocket onto the clutch assembly on my Poulan chainsaw

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

Where do I find the serial number on model number PP4218AVX?

It was very often just on a decal stuck to the top cover, some have a plate on the drive side just to the left of the chain catcher.

I have a model pp4218avx.when i try and start leaks a little gas out the exaust muffler and wont start

I had this problem and I have no idea how it got fixed, because I carefully took everything apart and put it back together. WOW-it lives and doesn't leak. The only thing I regularly do is inspect gaskets and turn them over when possible. I also am very careful to tighten opposing bolt patterns and evenly when there's only two or three.

Yes i cracked the oil housing for my poulan pp4218avx 42cc chain saw and I was wondering if they sale a replacement housing to repair the saw.

A Poulan PP4218AVX Gas Saw link follows:
See the "Handle, Chassis and Bar Assembly" print, item 38. Is this what is broken? If yes it is possible to replace it, it is not terribly expensive, it is a great deal of precision work. I hope you already removed the clutch (left handed thread). I would probably keep this for parts and purchase a PP4218AVHD Gas Saw Type 2 as a replacement. HTH

The back post that holds the bar has come loose and turns

Provided your saw is a PP4218AVX, tThe bar studs are item 41 on the "Handle, Chassis & Bar Assembly" here:

If not an AVX the correct IPL can be found here:
The dash number of your serial number is the type.

The tank is usually split to install a new bolt. Please read some of the repairs here: Chainsaw thread (free to join)
Sealing the new bolt to the fuel tank is the hard part.
Good Luck

Poulan Pro 42cc Just Won't Cut It

The chain is directional, only cuts one way. If a new chain won't cut, it must be on backwards.
