090g

[Beefie]

i just got this saw from a distant relative. She is letting me see if I can get it running again before I give a final buy price. I am wondering were to start looking for bars and kits for this saw so I can get into doing some milling. I have looked at a few websites but they don't list this old beast for options . Any help would be great . Here is a pic of the new saw, One more thing this saw has never seen wood it was bought just for cutting Ice out on the locale lake for Sturgeon Spearing.

Thanks for any Help

Congratulations
....little i can see ,she looks in great condition.
JMO ..If it was mine i would'nt be milling with it - to good / to rare !
Hope your getting a family rate on it.
Pretty sure it just takes the large mount bars / 084,88,090 ect.
What are the small nubers on the chain ? Generally run 404 chain.

Would definately check piston and cyl first.Go the extra mile and have her vac and pressure tested /and
gears for rust/damage.....to good !!!!!

.....hope to get one one day! $'s !

That looks like a real nice find : I hope you get a good deal with it.

Thanks for the comments guys. I was able to get a carb kit and a new pull rope yesterday for the saw. I found out the gasline and oilpump line are still available. I will have to order them this week.

Has any one ever milled with 1/2" pitch chain . This is the current setup on the saw. I am trying to locate a .404 8 tooth sprocket so I can have some options for bars and chains. The problem is they stopped making this saw back in 1985 , thats 25 years ago ,parts are getting more difficult to find.

This is going to be a fun project.

Milling with half inch sounds like a waste of wood and power to me. The trend is to go towards smaller rather than larger chain. A 404 spur sprocket is available from Bailey's. They also have a lot of other 090/070 parts. Rather than a dedicated spur sprocket I's also look and see if a rim sprocket system is available for them.

It sure is.

I agree with you bobL . I want to get set up with .404 chain for doing the milling. I did not no bailey's had the sprocket listed, I didn't find it on a search. I do no it is a tapered shaft going in to this sprocket. For some reason I am drawing a blank on what the dif is between a spur sprocket and a rim sprocket. I guess my brain isin't working to well been down staires cleaning that beast with some simple green. It almost looks like a new saw again.

DO a search through baileys online parts to find pics of spur sprockets and rim sprockets. A pic can explain it better than words. THe purpose of a rim sprocket is that when it becomes worn you only replace that rather then the whole rim.

I am not at all familiar with the gear driven 090 but the standard one and the 070 use almost all the same parts. obviously the bore size of the piston is different. the other difference is the clutch on the 070 is a 3 wing clutch and the 090 uses a 6 wing clutch. Not sure if the clutch drums are the same but do a double check.

Call up a talk with the gus at baileys as they really know their stuff and not everything they have is listed on the web site.

I would tend to agree about conveting to .404 pitch if only because .404 milling chain is so easy to find. Just out of curiosity what is the kerf on the 1/2" pitch chain.

I found a 090 sprocket at baileys, It does not specify if it will fit a gear drive saw. Waiting to hear back from them to see if it will fit.. I am not sure what the kerf is on 1/2" chain . the chain that came with the saw has been modified to cut ice. There is no top plate on the cutter just the side plate.

There are a few members that have a sprocket that I would need just need to figure out what I will have to part with to get it.

090G sprockets are entirely different - they're JUST a sprocket that I believe is keyed onto the PTO shaft. They aren't involved with the clutch mechanism in any way from my understanding, since the clutch on geardrives is usually on the engine crankshaft before the gear reduction assembly. And unless you have a custom spline drive made for rim sprockets, you're stuck with spur drive I believe. TeddyScout should be able to fill you in more on this.

Hey Beefie, just checked my 090/090G/090AV IPL (which has mod numbers up to 1996) and Stihl does (did) make a .404 chain sprocket for a 090G, it's P/N 1109 642 1310 it's a 8 tooth. The 1/2 inch is a 7 tooth, p/n 1109 642 1400. Try Stihl to see if they can order it, as they didn't stop making the 090 series in the 80's, the EPA made them stop selling them new in the US, apparently. Some drivel about "dirty" saws.... Now you can't get them in Canada either (we're just like sheep...)
I have a Canadian 090AV that was bought new up here in 95/6, and I have read they still are availiable in Aus, Costa Rica, SE Asia and Africa, to name a few places.
Brmorgan's right, they are flanged spurs with a key drive on a shaft.
Good luck in your quest!!

Thanks for the part # on the .404. Now At least I can see if I can locate one.Does anybody have any pics of a 090G set op for milling?

[Brmorgan]

An 8-tooth 1/2" sprocket would sure throw some big chips if you put the big 137cc topend on it. Was such a sprocket ever made? I'm sure that engine would have plenty of power to pull it on "shorter" bars.

I haven't seen one used for milling but if the saw was to be used in a conventional bar clamp setup, the long forward facing gearbox shifts the weight of the saw further back than usual. This begs for some kind of bolt to the bar or GB mill kind of arrangement. One problem is the bar bolts onto the opposite side to a conventional saw so a custom arrangement would be required.

 

[BobL]

I've been thinking about mill mounting on the 090G and because the wrap handle is rigid I would use a double vertical and mount the uprights direct to the wrap handle. Removing the dogs would then create a maximum bar length cut. I would even consider making a CS mill for nothing for any 090G owner if they left it with me for say 3 months

 

[ray benson]

I remember reading Chainsaw Lumbermaking and he said the gear drive saws were good especially for big wood. But there could be problems with shortened transmission life due to lack of lube because of gearbox position during milling.

well how much is it to ship it across the pond:hmm3grin2orange: I was kind of wondering about the power head weight being too much for the bar mount in a chain saw mill application and too much torque may cause casting falire?

Yeah - you could probably easily buy a mill for the price of shipping.

Beefie

The weight is not that much of an issue it's the protruding gearbox on the G that gives it a positive and a negative aspect.

The negative is that with the location of a conventional bar clamp mount, the weight of the power head will cause short bars to bow upwards towards the middle. And the powerhead will hang out further than other saws which will unbalance the mill.

The positive is that if the mill can somehow be attached to the powerhead so the full extent of the bar can be used, the protruding saw nose means the log is less likely to rub or contact with other parts of the saw such as the muffler or oil tank. This can be a nuisance on snubbier saw nose designs like the 084/880 when used in a powerhead mount and trying to use the full extent of the bar. The 076 also has a slightly longer saw nose and is good from that point of view.

Bob would you like some pics and measurements to get those creative juices flowing.

Yeah OK - post some close ups of the saw nose - both sides, and top and bottom.
Include the relevant bit of wrap handle in all of the shots.

 

[Beefie]

I will see if I can get some pics tommorow. Do you need any measurments?
