My enquiries in 2017 to 10 possible suppliers of this part all resulted in them saying it was no longer available or obsolete.

Just now, typing in '16372X Oregon' on Ebay yielded two new ones in the USA, one of then costing less than £30 with postage.

It may be worth enquiring to Makita/Dolmar dealers in Germany. Thay may even have the original spur clutch drum marked as 113 223 091 on my Sachs Dolmar 123 parts diagram. Not sure what the Makita part number is for his.

Thanks

I saw one website which suggests that it is the same size as a 9010 drum.

Didn't have any problems getting one for my 9010 recently from L&S so shout if you want me to measure that one up to compare.

That would be useful information to have, but please do not dismantle your saw specially to measure it!

The original drum, which a 16372X Oregon rim sprocket drum replaces, is 74.23 mm outside diameter, 69.24mm inside diameter, centre hole 17.93mm, depth of drum near outer edge 20.37mm, overall depth of unit including spur sprocket 30.29mm.

No problem, doesn't have a bar on just now so only need pop the circlip off.

Seems like it's a bit different I'm afraid
80.2 OD, 76.9ID, bearing bore 16.1.

[Dan Maynard]

That's got me thinking your bearing at 18mm is pretty big. Don't think that would match my 112 or PS-6000i either.

Yes indeed, but thanks for checking it.

Getting a new needle roller bearing for it was not easy. The Makita replacement part has a plastic cage, whereas the original Sachs Dolmar's was steel. In the end I found one with a steel cage at a bearing specialist in Germany.

Hi People,

 

I have the following part numbers:

 

123 223 101 CLUTCH DRUM

957 223 123 CLUTCH DRUM CPL

 

Not sure if these are the clutch drums you are looking at?
