Got case halves matched up today, 9 cases. Still need to go over them in detail, looking for stripped bolt holes, cracks, etc. I’ll make what repairs I can do and throw the rest as is on eBay.
sorted all the smaller parts, including screws…sheesh…what a pain trying to read the tops
12.9 and 10.x. If I couldn’t read it under magnification it became a 10, lol.

Just heard this week that the 9640 003 1850 Oil seal 17x32.9x3.6 (PTO side crank seal for 064, 066 and MS660) is NLA on its own from Stihl. It is, however, still available as part of the full set of gaskets and seals, part number 1122 007 1053. Apparenetly as the MS660 has been out of production for over 10 years now parts are starting to become obsolete. My dealer also mentioned that the back handle/tank assy for the MS660 is also NLA.

I would suspect a certain level of inventory still exists among domestic US suppliers considering the number of units sold and still in professional use in the States.

Worst case, AM replacements are readily available.

I believe the MS661 use the same PTO side seal. Probably Stihl got supply issues.

You are dead right, I have asked my dealer if it is temporary supply issue or permanent

Dealer has just emailed and said the 9640 003 1850 Oil seal now supercedes to the 9640 003 1851 oil seal on the NZ Spec 661C (MS661 C-M-Z). Same dimensions so no reason why it wont work on the 1122 series. He has no idea why it doesn't automatically supercede in the system on the 1122 parts lists.

Indeed it does. My initial lookup for the part number was from MediaCAT which obviously didn't include the 661 in 2012. A quick check of my MS661 IPL shows the same part number.

I knew the day would come when we would be having these conversations. Sad day for sure. I feel that the 1122 series saws were some of the best saws ever made.

I have been stocking up on parts for a while. There is still a fair amount of supply. There is even some heated handle stuff if that is what you are into.

The flywheel side seal has changed also from 9640 003 1560 to 9640 003 1561.
