Chainsaw Repair

Poulan 475 76.5cc this saw showed no signs of anything wrong. Pulled 36" ripping like a beast. Psi felt good IMO. Priced it to a guy with used topend and BB372 piston and used oem 475 piston.
I wanted to check the piston etc so I pulled the muffler to see how things were looking on the afm piston. Noticed a scuff right side. So I pulled it down and called guy to tell him. He told me to go with the NOS 475 topend kit I have and I would do the swapping labor free.
Then while down I pulled it down to check seals etc. Seals still good but the crank bearing had rough spots. So called the guy and told him no go on this one for now. Oh well better to find out now then ruin a good NOS topend.

Used pulled 140psi with base gasket, but felt more then that to me.     Guessing 8 tanks on the afm piston and rings.

Looks like I will be pulling wild thing 505 apart and throwing on the NOS 475 stuff on it with the covers etc.
Just no time to be splitting and doing bearings on saws right now.
Have a 505 down with a pto seal bad. = $35 bearing seal combo and split. One thing that is a draw back of the update. But is also the same bearing set used on the 385 390 saws.

One of the reasons I tore my 475 down was because of the bearings.    The symptom was that it was getting hard to pull over with the pull rope.    When I got it tore apart and pulled the bearings out I could see where they had rusted at one time. 

Did you come up with a redneck tool for the worm gear removal?  I dont have anything yet that fits.

I think I took an existing puller I had and modified it with a burr and my flex shaft.    It was awhile back.

Stripped the 475 all the way down to where the crankcase could be split. Not going to use the right half anyways as it was the half I had to redneck repair.
Will use a 445 crankcase or other 475 cc. All I want from this 475 was the good crankshaft for the 445 or other 475.  All the parts put in a bin and shelved. 

Still havent come up with anything to fit this freaking worm gear. Guarandangtee ya no freaking worm gear will be going back on with the nos 475 seal and bearings. Will all be updated bearin seal and oiler system from the  505 445 425 stuff. 

Roger do you know the part number of the husky part?  I have seen about 3-5 like that in a set in  past for different saws.

I have a 3 jaw small puller but no way it has the clearance your has.
