Itís supposed to be crowned.  That makes the blade track correctly.

In a conversation I once had with a Gates representative He said that the manufacturing process had improved to the point where buying a matched set was no longer necessary but from a marketing standpoint if that was what the customer wanted  they made them available.

  I disagree. My understanding is WM advises and they supply flat surfaced B-57 belts to get the most traction on the blade. Sorry - no offence intended.

It's interesting when I bought my mill in 1994 Woodmizer actually recommended belts with a crown on them. If memory is correct it was Browning that was one of the brands recommended and I think Goodyear as well back then. I found it odd when I got replacements from Woodmizer one time and they were flat back ones. I phoned about it and asked about that and they said it has changed.
My mill manual in the troubleshooting section for poor blade tracking it states one of the reasons could be flat belts.
Regardless, the new belts they supply work great so either way would work I'd say.

Yup, Wood-Mizer's B57's are specially manufactured for them and they are flat.  They are the only belts that I have actually used.  I say "used" because for some unknown reason I tried the orange belts once which were a total failure.

You are correct donbj, but I suppose R&D led them to the present B57's.

Yes, they don't shy away from the R&D that's for sure. The surface contact and traction makes sense, especially for some of those beasts that drift across your mill!

The belt situation is not as simple as it seems. One argument says use B56 belts that fit tight so sawdust won't build up in the groove. The other side says loose B57's leave a way for the sawdust to get OUT. Been my experience if you get sawdust buildup under the belt, you have other problems. Flat versus crowned..Mount a blade over a crowned belt, apply normal blade tension..Now look under the blade...What crown. It's mashed flat by 2000 lbs of pressure. The crown is mashed flat and the released every revolution of the bandwheel. All that flexing leads to a much shortened lifespan. The real gotcha is a different internal construction. Slice across an old crowned belt so you can see the internal structure. The cords are in the sidewalls, none under the crown. Compare to a flat top belt, there is a layer of cords under the flat top. Again, experience the woodmizer belts will outlast the parts store ones by a large margin. Cheaper is more expensive in the long run.

Very true, Piney!  thumbs-up

I've most always used the Wood-Mizer B-57 belts, except one time I had a blade break and took out the idle-side belt!

I went to the parts store and picked up a regular B-57 to get by with until I could order another pair from Wood-Mizer!

The parts store belt worked fine, and I only had about 1,200-1,500 feet to go on that job. The belt looked severely worn when the new belts arrived 2 days later!

As Piney stated, the parts store belt does a lot more flexing and it's lifespan will be much shorter!

 Lets keep a couple things straight, B56 belts do not get sawdust under them ever.   I run any old B56 and they last a LONG time.  Maybe with the B57 going in and out of the wheel is hard on belts.  Steve

Has anyone experienced a broken belt? I did last week.  I dug out a piece of pine knot with a screw driver that was lodged in the wheel groove.  I assume that was the cause.  I replace it with an old one that I saved from last belt change.  

When I get new belts, they will come from WM.  I don't feel like experimenting with other sources.

do the WM belts fit the surplus center sheaves just as well as the sheaves WM uses?
