1100cd...The Resurrection and porting

[Chainsaw Jim]

Here's a gem of an old saw that was originally getting new seals, carb kit, a bath, and whatever else needed for a full servicing.

I say originally because when pulling the flywheel I discovered the crankshaft sliding side to side with zero resistance. After splitting the case I found what I expected...

The inner race had spun each side of the shaft down far enough to junk it. So I was very very fortunate to receive replacement from one of our favorite members @jacob j.
Thank you Jacob!!!

I regret I didn't get a pic of the replacement, but I'll tell you the weights were still shiny with a mirror like finish, bearings were perfect.

Good Ole Jim, always working on that old metal! Ever grind on one of those?

Yes, here's another one I did last year for Ross. He put a pipe in it and I suspect maybe advanced the timing some but I haven't asked him on that.

Ross is getting it dialed in nicely. He had it at the pnwgtg and it was very impressive.

Here's a few pics of the process..

Some very light surfacing


New bearings


I used my stihl crank tool to pull it in place.


A close up of the brand. They are some of the smoothest bearings I've ever spun.


New oem seals.

I ran a paper towel through the crankcase to wipe the red loctite clean.


I apologize for the graphic content. Lol

Fantastic! Great work!

Jim, where are those crank bearings from?

 

[Chainsaw Jim]

I ran across a little hidden damage in the beginning. These little chunks of the case were flaking loose..

..I picked the the rest of rim clean and smoothed out the area.


Unfortunately what broke loose was magnesium from the case which claimed the cylinder and piston.


I searched around and couldn't find anyone with a spare so I decided I'd give up the cylinder with matching stamp piston from my saw. The damaged cylinder had a smaller piston combo so this will be better in the long run.

So add the set brand new oem rings on hand and were now back to this emoji..

The stock numbers are: 103-122-69 with the oem gasket, with a squish measurement of 62 thou.

They're from a bearing supply store near me. I'm hoping it's their regular brand.

Unfortunately it claimed both the cylinder and piston.

Holy crap Jim, it is really amazing how far these things will go before they stop!
