Poulan 5020 3/8 to .325 Conversion

[ColdNorCal]

Bought a used pp5020 and want to use my .325 18" bars and chains. Researched about doing a 3/8 to .325 conversion and on another web site a person said he was able to convert from 3/8 to .325 using a Stihl drum and different wrist pin bearing. Im in the process of confirming that and am hoping someone else has done this conversion.

Given their is not much info about this, Im thinking it cant be done...

guessing yours is spur?
i just went the other way.
325 to 3/8lp.
pp335 had rim & small spline drum, meaning i only needed sprocket.
oregon makes them, and likely the drum you need.
stihl's small spline stuff is enough different it wont play nice w/others.
there's a poulan thread here. might wanna ask there.
