285 cd

Looks so much like my 480's, must be inbred cousins. Always liked their reliability, not so much the 19 lbs (empty) - still have a few, actually my original one from around '78 I'm thinking, still runs. Not a high rpm unit but hard as heck to stop.

 

[computeruser]

Looks like fun! I need one of those, one of these days...

The 285 is the same basic saw as the 298/2100/2101 but with only 85cc, matter of fact the 298/1100/2100/2101 top end and fuel tank are direct bolt on parts. Biggest difference between them are the 285 lacks the manual oiler, it uses a different style recoil and I believe a different flywheel.

Nice project you have found there. My first 2100 was actually a converted 285.

EDIT:
The clutch cover is the only part interchangeable with the 480, to the best of my knowledge.

 

[Ranger Dave]

got the flywheel off, yuck.

timming mark

spring from the seal in the bearing

Will a 2100 top end bolt up to a 480 though?

 

[Roanoker494]

No because the 480 block is much narrower than the 2100. Also have the problem that the 2100 had a 40mm stroke and the 480 was only 36mm.


Ranger Dave,
If you have a local Tractor Supply you can pick up spray cans of Husqvarna orange if you decide to do a full restoration. I have had good results with it as long as I give it a couple coats of clear to help with fuel/oil resistance.

I had my 285 out today, it's a freaking hoss, you'll really like it.

Oh lord, I want a 1100/2100/2101....but the 285 I have is awful slick looking and runs so good it would be a shame to put another top end on it.

Here's a vid


One of these days...

Haha, that saw used to be mine. I was surprised how well it ran. If I was into old saws, that would definitely be a keeper.

I know that feeling :cool2:
Some times I just don't wanna molest the strong , good looking saws . They're also a pleasure to run stock . :msp_thumbup:

1100 didn't have manual oiler either?

At least mine doesn't, it is 99cc though, and the later models don't have much, if anything on it.

Not sure about the 1100, but the 298 did NOT have a manual oiler. The 1100 and very early 2100 had the Femsa flyweel and related ignition, then they changed to the SEM type. The flywheel and ignition shown here of Ranger Dave's 285 are the Femsa type.

great work so far....looking real clean.
