Yes it can be removed. Saegenspezi sells replacement rings. Complete NOS/new OEM assemblies (fan including cup and ring) aren't that expensive, either. I think I paid around $35 for one. Saegenspezi probably sells replacement assemblies, too, for a fraction of the cost of OEM.
As for how to remove it, there has to be a fairly easy way, but I just went after it with some Kroil, a punch, hammer, screwdriver, snips, etc. If you had a slide hammer setup that would probably be the best route, but then you'd have to put the starter cup in a vise, and I think it would deform fairly easily.

Thanks for info. Had already purchased a new ring just wasn't sure about taking out old one. A hammer and screwdriver worked well.
Working on another Contra but this one has some damage to the cylinder bore just above the exhaust. The coating is off in two small areas. So I'm looking for a cylinder for a standard 1106. If anyone has a usable one they are willing to sell let me know. If I not able to locate one I will have to see about recoating.

Cosmetic outside damage.
Cosmetic outside damage.
my dealer and i were having a chat about 070/090 clutch and flywheel weight differences and how it effects the longevity and performance.
he said there were few instances where AM flywheel which had more weight than OEM and that gave the saw more low end, but snapped the crankshaft due to imbalances between crank and flywheel ?
we agreed with the heavier flywheel coupled with 090 clutch will be more balanced and will make way more power at low end, not sure how far the difference is in the wood though

Recoating your cylinder at www.uschrome will cost around $200-.In time you should be able to find a 106 cylinder at a better price.
As a footnote, don't try running 58x1.5mm 070 rings in your Contra, the correct 58x2mm Contra rings are available online.
i got an oem 58mm 070 p&c in very good shape if anyone's looking
Posted in another thread but might as well post here, too; the bracket on the muffler for one of my Contra's was confusing me... The directional exhaust is a new one for me. Hadn't seen that before. 
I have four Contra's apart now and slowly putting them back together. Instead of one at a time, I'm doing assembly line fashion, which gives me a better opportunity to compare the bits from different saws.
I'm working on the flywheel side case halves now -- noticed a few differences, so I thought I would share.
First, the dowel pins that align the halves are different - either 6 mm or 8 mm in diameter. Second, some halves have three holes drilled through the case. Not sure what they're there for. They're not threaded. See the pic - circled in red.
Casting appears to be the same for the earlier saws, but the latest one I have is lettered different - larger font.
What's odd is that it doesn't make sense when you look at the serial numbers.
100598 - No holes, small 6 mm pins. Small font on part number.
158819 - No holes, small 6 mm pins. Small font.
176143 - No holes, large 8 mm pins. Small font.
187610 - 3 extra holes, large 8 mm pins. Small font.
364797 - 3 extra holes, small 6 mm pins. Large font.
I checked my NOS 070/090 case half - different part number, but it has the 3 extra holes and the small pins.
So, I'm thinking the 3 extra holes was a running change that remained, and the 8 mm pins proved to be a bad idea so they went back to 6 mm.

Is anyone familiar with this odd 'hook' feature on what appears to be a cast cylinder cover for a 106cc Contra?
NTS - I just have one cast cylinder cover. I'll have to check it when I get home.

Thanks Scott. Between saws & parts I have a half-dozen other 106cc cast tops and none of them are like this. Searching around on the interweb I couldn't find any photos of one like this either. It just seems like this style would have fitment issue because of the air filter. I need to take a moment and try to install it on a Contra, which I should have done first...
Interesting. I have 6 or 7 of the sheetmetal tops but only 1 cast top.
