24" D009 D176 bars 81DL 84DL

Has anyone compared a echo 24" D176 81DL bar to a D009 24" 84DL
bar in 3/8 050. Talking total length of the bars?
Why I ask I put a D009 24" 84DL on a echo (yes I know the slot
on D009 is a tad wider then D176) with 84DL chain and I was at
the end of the echo tenstioner adjustment.
I am thinking I can remove 2 or 3 drive links and have full
adjustments.
Just wondering if I could get away with going to 81DL just like
the 24" oem echo bars?
I would check this myself. But have sold and shipped all my 24"
echo bars and 81dl chains off already.

Anyone got both bars 24" D176 and D009 to check total length
measurements?

Only have the 009 in 24. I was thinking it may not be the
total length of the bar 176 bar. The adjustment holes on an
009 seam to be a tad bit farther towards the tip than the 176.
I think that the overall average of a 176 is a wider , top to
bottom, over the length. Tail on a 176 is wider also. All 3
of those factors might be stretching the adjustment on the echo.

Thanks. Just wish I had a bar here in 24" to compare them. I
was going to cut 2 DL's out and go 82 with the D009. But was
wondering if I could get away with 81DL.
Hate having to rebreak one after putting together after cutting
it first time.

Don't take too many links out at a time, I had an old Mac. with
a hopelessly long chain & I pulled three dl out of it and had to
put one back.

Another idea. 3 links should be 2 1/4 inches total out of the
chain- drivers, ties and cutters. If you are at full
adjustment out, I figure that it will pull the bar in 1/2 that -
1 1/8". I'm not at home to do an exact measurement. Guesstimate
- an adjuster has at least 2 inches of travel. So there's a
little room to work with. If it was me I would just do it.
Only my thoughts.

Actually, I do have both - I think. I have a 24" Oregon
PowerMatch D174 81DL bar I got for my McCinderblock SE3420.
Then I have the bar that came with my Chinese G621 clone, which
should have been a D176 mount but was not. Near as I can tell
it's a D009, and it flopped all around on the studs. However,
the oiler and adjuster holes worked.
The one bar is simply an inch longer than the other, so I refer
to the 81DL bar as a 24" and the 84DL bar as 25". I run them
both on the clone. I have not had issues with being at the end
of the adjuster range that I recall, but I will look at it again
(EDIT: you can see in the attached picture where it runs).
I made my own bar adapter, which is not perfect but it works. I
save those thin SS strips from old wiper blades and have made
many tools out of them. Here I heated the end and bent it
around an old bolt, making an adapter. The metal was just a bit
too thick so I had to grind it to fit, but I've used it quite a
bit now.

You just gave me a reason to tear down some old wiper blades for
future use. Thanks for info too.
The D009 bar on a echo 702 is at the end of tensioner with 84dl
chain.

They must just have the bar studs positioned differently
relative to the crank. Of course, who really knows what the
heck this Chinese bar pattern is?!

That will of course explain some difference, but 3 dl is quite a
bit. Btw, it is the adjuster pin vs. the crank that really
matters, not the studs.
