DoAll 16-2; Looking for drive belt sizes

We've got a DoAll 16-2 at work, circa 1958. We bought it used and the original belts were worn so we replaced with the same parts but they've never felt right. The speedometer and manual suggest the saw should run to 1500sfm yet ours can barely make it to 1000. Not to mention we get horrible vibration around 5-700 and the upper drive belt is constantly loose and slapping. Its bad enough that on moderate cuts, like 1" aluminum, the belt will slip completely and stall the blade.

The machine has a placard on the rear with all of the part numbers, but they appear to be DoAll part numbers and not industry standards. I tried searching DoAll website and none of the belts nor the 16-2 machine can be found in their records. An email to a parts associate got me as far as "I can't tell you the belt lengths because they are still active part numbers" and then a link to ONE of the two drive belts, being listed at $68 and a two week lead time. McMaster has Gates belts for under $20 delivered tomorrow so obviously I'm not going the proprietary route for a V belt on a machine this old.

All that being said, I am looking for the two drive belts - from motor to variable drive, and from variable drive to transmission.

For the lower drive (motor to variable):
Current belt is a B37, or 40" Outside Circumference.
The machine came with a 5L400 belt on it, same OC just lighter duty
The placard calls for DoAll P/N D35-7081

For the upper drive (variable to transmission)
Current belt is a B40, or 43" Outside Circumference. This belt vibrates and slaps due to too much slack.
The machine came with a B41, or 44" belt.
The placard calls for DoAll P/N D6215. This is the belt the sales guy was able to link me to, and according to the website it is a 46" V belt.

Our motor is in the standard location at the bottom of the cabinet and has a 3" pulley. The transmission has a 9" pulley.

I have been scouring the internet for information on the saw and have found a PDF of the manual that does not contain belt lengths, and a few forum topics from people restoring 16-2's, but still no mention of which belts to use. I am hoping someone who has this saw can help me with their belt information to save me some time playing guess and check with McMaster.

Thanks in advance

On my 1612 DoAll, I trashed the Reeves drive and updated to
a 3hp motor and a VFD drive. No more noisy pulleys.

-D
 
An excellent update I'm sure, but a VFD and a new motor I'm sure cost more than the belts. I don't mind some noise from the reeves, but the slop and vibration are clearly incorrect lengths and not the standard noise.

First off, you posted this in the wrong section.......
The last time I bought belts for my saw, one belt was part #1626V455 and the price was $52 plus shipping in 2019, don't have any info on the other belt, can look tonight when I get home if I still have any info.

The DoAll belt prices are not that bad, and you get the right ones the first time!

I would start calling band saw service centers and see if they can help with belt sizes.

Here's a couple of places I have had good luck using:

Thanks. i figured it would have fallen under "USA light iron" category.

The part number you sent me is for a 1" wide, toothed, "timing belt", which I did suspect might be my first problem. Our saw is running 1/2" wide V belts.

IIRC, the belts on my saw, one was wider than the other.......what are the widths of the fixed pulleys on your saw, that will help with the width of the belts needed.

My saw is from the early sixties, it may not use the same belts sizes as yours.........again I would call a belt specialist or saw repair, they should be able cross reference the DoAll P.N. that's on the tag for the machine.
