I probably ought to have mentioned these years ago because some of our crawlers have issues with getting a new fan belt on due to the prop shaft for the hydraulic pump.
Acculink belts are made to length as they have individual links which snap apart / together. They also can be threaded into place and assembled. Nice.
I was reminded of these because my lathe speed selecting drive belt packed it in. A big piece popped out and, bump, bump, bump. To replace it, two shafts with several pulleys on each have to be removed. That's a lot of roll pins to push out, not lose, and then get back in. Unlike a drill press or a milling machine, the lathe buries all this inside a framework which is the headstock (not handily on top). Ugh.
So, I immediately recalled how my Toolmaker father used to deal with these. Acculink belts. Finding one was easy. Harbor Freight. One over in Sanford about 15 miles away. They carry the A belts in 5 foot lengths. Costly, yes. $33. But worth it as it made the belt job way, way easier than the 'normal' way.
Hey, Lavoy, old buddy: You ought to carry these. Way handy!
