Anybody have knowledge of Gates industrial belts, need an odd belt...

[1 Wild R/T]

So, working on an older piece of agricultural equipment.... A tree shaker for getting the nuts out of trees.... It has recently been eating belts, I replaced the bearings in the idler pulley and the bearings in the shaking component also replaced the bushings in the hinged arm... Now I'm trying to source a proper belt... All the places are offering a belt of the proper length but the wrong shape, What they are showing is a hexagon shaped belt with equal length sides... the equal length sides lets the belt roll in the pulleys... The original belt for this machine is an elongated hex, the long sides create a deep V which rides deep in the pulleys preventing the belt rolling over in the pulleys... The shaking is pretty violent & the belts get a lot of weird forces acting on them..

The original Gates belt number is CC210X/AEXP. The belt cross section is shaped similar to my sketch

The belt being offered is a CC210. It's cross section is shown below...


I've tried quite a few local suppliers including one I use to work for... I've poked around online... I've had no luck.. So I'm hoping someone has a background in this sort of thing and can help me sort it out... Thanks!

I've had a bit of a poke around also, and seen pretty much everything the same as your hexagon types above that won't work.

Have you considered changing the drive to Serpentine at all? Gear and idler changes ....may be able to find a belt that works, and more importantly one that stays in place while the machine is running.

I ran your gates # through a large John Deer parts sight and only come up with V belts to cross over.

Wow, that's a strange shape for sure. The double belt in the bottom photo is used on riding mower decks and they are designed to drive off both sides. Some of those decks have a crazy belt routing.

Changing to serpentine won't work, the belt routing causes the belt to turn in ways a multi groove belt could never duplicate...

The picture below is of a newer machine that doesn't use an idler but it is similar....

Plus the belt is 210 inches long, about 7/8" wide and 1 1/4"

I would bet the belt he needs is a double angle belt. A careful look at the pulley angles will tell the story. If they are all the same, the double angle is what you need.

OK...so if a Serpentine belt is not going to work ...how about a custom-made round belt?

Just trying to think about how you can get up and running again.

I appreciate that, working on industrial equipment I've worked with round belts a fair amount, they suck where you have any serious amount of power/torque...

It is currently working, the farmer had stocked up on belts back around 2000 when the local tractor parts house was closing...

Unfortunately after breaking four belts this past harvest he only has this one last belt left so if it fails he's gonna have another problem...

Funny thing, the machine had been averaging three to four years out of a belt but when the bearing went bad it killed that belt and since replacing all the bearings in the various pulleys it killed three more belts...

Turned out the pulleys being loose allowed them to move with the belt, the belt was getting tossed more than normal because the swinging arm that clamps the tree trunk was flopping around due to worn bushings (to the point the pin was riding on steel instead of bronze) & guide surfaces...

I bored the bushing bore oversize, machined a repair sleeve, welded the sleeve into the arm, replaced the bushings... Machined a new pin... Welded up and machined the area where the guide pads ride.. Machined new UHMW wear pads... Generally rebuilt the head to like new condition & now it doesn't toss belts....

But if it does the man needs a spare... Or three... Downtime during harvest isn't an option...
