Oleo-Mac 985HD & Oleo-Mac 999F
« on: October 11, 2012, 04:27:03 am »
I'm curious as to what the forum members think of the Oleo-Mac 985HD and 999F chainsaws.

How do they compare to other saws in the same engine capacity.

From what i can see the 985HD has a brilliant air filter system and the 999F looks like a nice alternative to a Husqvarna 395 or a Stihl 066.

Gypo AKA John Lambert had a 999 that everybody and his brother tinkered with .It was set up as a torquey miller at one time and had plenty of grunt .Big Dave reworked it to gain a little speed which it did .

I mean the thing had some grunt but actually if it would outdo an 066 or a Huskey 2100 it's hard to say .Definately  a saw worth acquiring if you could find one .That brand is just something we in these parts are totally ignorant about because they simplely did not exist .

These Oleo-Mac chainsaws have a serious air filter system. If only Stihl and Husqvarna could make such a decent air filter.
In ways, they look a lot like early Solo chainsaws - 670 -680 and 690- 603 series.

Filter reminds me of the HD air filter option on the dolmar 7900 now days.

Was there a standard air filter set up  and HD filter option on the 2 you posted above too?

I've only seen a 999 around here and they seemed to weigh a ton.

Those air filters are totally standard equipment - quite impressive to see an automotive style air filter on a chainsaw.

The 999F uses a 3 element filter with a removable and washable outer filter element.

Does anyone know what the piston pin diameter is for an Oleo-Mac 999F.
From what i understand the piston is 56mm in diameter which is exactly the same as the Solo 603.

I am trying to find a replacement piston for the 603 but it has a 12mm wrist pin diameter. I'm hoping the 999F also has a 12mm wrist pin diameter and similar piston dimensions to the 603.

If memory serves me correctly old Gyp was going to replace the piston in his 999 but the danged piston was like 150 bucks .So I'm thinking it's kind of a toss up of which is harder to find parts for ,the big Oleo or  the big Solo .

Stick all the parts in a box and remember where you put it and eventually some day when you least expect it the parts will pop up .That's kind of the way it goes most times .
