Alrighty then, I put the D176 mount style bar on the Roper that requires the D082 style bar. Of course it fits fine. I put one of my brand squeaky new (20BPX074G) 74 link chains on it, and it is fine for length, even has planny adjustment room if it stretches to keep properly snug. Then I took that same combination and put it on the other Roper (917.353770) and it fits fine. Supposedly the D082 saw needs the 74 link, and the XXX770 saw with the D176 mount and that bar is supposed to take a 72 link chain. I don't see that need. Both saws fit that bar fine, the chain is fine on both saws. I don't get why Oregon tells me otherwise. So I am still game for a 180PXBD082 bar just since it is "original," but also in the market for a 180SKBD176 bar which although I have been told is still available, I cannot find it and Oregon tells me they don't have it.
So, being the typical black hole of need you have all become accustomed to seeing me as, I am in the market for either bar, and if someone does know where to get that 180SKBD176 bar, I'll buy one new and get it sent out here from somewhere.
I did find a gentleman in the MA area with one, and see if I can work out a way to secure that item; we are communicating by email at this point and he likely recognizes me for a lunatic. I suppose, he's not too far off with that impression.
On a more celebratory note, I did get a nice package in the mail today from 67L36driver, a starter sprocket!!!!! I will work on that this weekend and let you all know how it comes out, with pictures as well. There is a subtle difference, the "new" one has three prongs for the starter pawls to hook into, while my orig has 4. Honestly I do not think this matters at all, as that saw was used for a long time with only one starter pawl instead of 2 with out a problem, unless it was one perhaps of balance. More to come later.
Here is what the
917.353750 looks like, (the one I am working on in this thread) followed by its D082 style mount, followed by a modified bar to fit it. You can see the oil holes were drilled and the end clipped off. You can also see the oil hole in the channel so I think this was actually a modified D176 bar made to work on this saw.
Now here is the
917.353770 saw, followed by its D176 style mount, followed by the proper bar for it. You can see the oil hole in the channel.
The difference? Note where the oil holes are. The first saw D082 oils into the thru hole in the bar, which is closer to the mount studs, while on the D176 mount, the oil hole is further away from the studs, and seeps into the weep hole drilled into the channel.
