Poulan S25 CVA Part question. |
|

|
Looking to overhaul and reseal a 1980 ish Poulan Super 25 |
|
counter vibe and having trouble sourcing the crankshaft needle |
|
bearings. The Husky # 530032021 is discontinued. Does anyone |
|
know the size and or a source for these bearings? This is a good |
|
running saw and if I cant find the bearings, I dont want to |
|
brick it. I see lots of parts for this on E bay except for |
|
crankshaft bearings. |
|
Any help would be appreciated. |
|
Rich. |

Thanks. I saw those. But I don't want to replace bearings with |
|
used. I'm hoping to find a bearing number when I get it apart, |
|
and possibly source from a bearing supplier. I'm not confident |
|
I'll find a number on the bearings though. I gotta believe it's |
|
a standard size bearing. There's enough of these saws on ebay |
|
that are being parted out, one could actually build one from |
|
scratch if so inclined. Ive already scored some new old stock |
|
pieces I needed. |

I spent the day tearing the S25 down knowing the bearings are on |
|
the way. Picture confirms it's the exact same bearings. I |
|
measured the crankshaft journals and they measure out at excatly |
|
9/16 (.562") no wear at all just slight discoloration where the |
|
bearing runs.The big end rod bearing has some up & down slop. I |
|
also ordered that bearing. I'm not sure about the piston. it has |
|
vertical scratches and had slight blow by all the way around. |
|
Cylinder looks pretty good. can see crosshatching everywhere but |
|
with some shiny spots. Cant feel anything. It's all very smooth. |
|
|
|
Anyone know what or if the cylinder was plated back then? I |
|
confirmed this is a 1980 casting by the cast in number on the |
|
case. Any recommendations on a piston and rings? I haven't |
|
checked the ring end gap yet. Also noted the ring groove has no |
|
locater pins. Not sure how to clock them on reassembly. |
|
Fun little project. See pics. |
|
Well the pics suck as I had to shrink the file size to post. |
|
The number on the bearings are the same as in my earlier reply. |
