Confused? 72 vs 70 drive link

[HarleyT]

The poster or picture is informative however I think there must be a better one for 2015. I see some errors or out of date stuff. They do not really show the difference between A and K on the 095 and 041. The Stihl 3005 mount which is 074 must be an obsolete one the newer one gets fatter faster that one won't be wide enough soon enough to meet the oil input spot on the current Stihl products. I found out this buying new old stock.

The D176 seems to be of the get fat fast tail type. This must have some advantage but seems to be more drag and more wear in the first inch or two. I guess for a brand x bar it is more the slot, adjuster and oil locations.

Yeah, I was looking for an Oregon chart online, Bing found that one..... It is off of the Alibaba piratesite

or 1/2?

No, it roughly is one, as you can't just add a driver - there will be a side strap as well.

 

[SawTroll]

The Z means different drive link count than the more common letter. In this case K. Isn't an 095 often called small Husky mount less oddball than D176? This being Oregon numbering system.

Yes.

So have you actually measured 93DL bar for usable length and total length? or are you just going by what you have read online and guessing again?

Use the inside of you head, it isn't that hard!

I already have and know

Still waiting on you to show actual measurement of both.

Another Oregon chart;

Here is the newest used today A095 bar. A095 on left and K095 on right. Then with the A095 on top of the K095 to show how much narrower it is.

First hand info not just read online and repeated.

What is the story of the bar on the right? Those are some rough looking edges!!!

What's the difference? Will both work? I am eventually wanting to run a good 72 dl 20 inch bar on both.

I have seen other ECHO saws where the OEM bars use chain loops that are 1 or 2 drive links off of 'standard', more common loops - I assume this is to keep customers coming back to their ECHO dealers, instead of buying chain elsewhere.

To the OP: once you decide on the bar(s) that you want to run, you can have your chain loops re-sized at a good saw shop for a few dollars, so that you can still use them if they have a lot of life left in them. It certainly would be convenient if both of your saws ran the same size/type of chain.

But just in case, I'll put this up so folks know what we mean when we say "D176" etc....

Any excuse to show photos of good tail here on the Internet . . . .

And I was working on a good dog joke in response to the Husky tail comment...............

But we digress..................

I wonder if the O.P. will ever post again..............

What was his question?

70DL sound like an oddball length since 70 isn't divisible by 2, thus creating 2 left or right hand cutters following each other. Not that that really matters.

 

[jughead500]

well in case he does i believe i know what he's getting at.
the bar on your cs 590 is more than likely 70dl which should be a d176 mount.in order to use a 72dl chain you will need to go with the husky large mount bar which is the d009 mount and use bar stud spacers.may also have to drill out the oil supply hole.

Hard as heck solid german made bar.

Or 4.....
Hey John, I enjoyed your message on my phone the other day!!!

I find that odd that 70 isn't divisible by 4. Lol
Ya, too bad you weren't home. Will try again.

Fuzzy Canadian Math.......

This is almost as good as an oil thread. What I've learned so far is that there are different bars that different saw brands use and that not all of them have the same length chain. Oh, and the sky is blue.

I believe that is the most convenient way, if 72dl is a must.

skys gray here.lol something tells me op was drunk posting and forgot where he posted or we've been brush aped.

comes in handy when you use 72dl chains on other saws but for me i had oddball mcculloch 70dl.so i was still SOL.

Sorry for the stupid question... I just never paid attention... And I'm new to this..My family has sold saws since they where invented and my uncle is a saw expert..so is it the bar sprocket or the drive sprocket that's different on a 72/70
