Chainsaw Repair

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.

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.

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.

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. 

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?!
