A belt failed while operating the Motor Grader. Here I replace the broken belt with a new one and explain the drive system.

Spare belt half installed greatly reduces MTTR. Sharp thinking...

Frank, one thing I noticed when you had the belts engaged and running, was that the pin that runs through the idler pulley is spinning. I would think you would want that to be stationary, or eventually it will wear out the hole it runs through. With just a cotter pin retaining it, it may wear through the cotter pin and the pin could work it's way out. Just my observation. The fix might be to weld a tab to the idler shaft and bolt it to the tensioner arm. Good video, though. Keep up the good work.

It did spin some, an yes, that's not good. Due mostly to newly lubricated needle bearings in the pulley. It stopped after a couple minutes.

@@woodandmetalshoptime8048The best way l found to keep a bolt-shaft from spinning, is to get a junk socket that corresponds to the bolt head cut a slice of said socket, thickness matching bolt head height. Now snug bolt in position, place socket slice over bolt head and weld outside diameter of socket. Now finish with castle nut and cotter pin

Fun fact about belts. Even when belts have same part number they have different lengths. When running multi belt setup you not only have to match part numbers there are matching numbers that you match the size.

Yes. That's more important in some applications than in others.

The dual belt set up is for redundancy, not power transfer. I recognize that one belt will take most of the load if they are not matched. That's OK, and pretty much insures they will fail one at a time, leaving the second belt to get me home. So, in this special case, matched belts are not needed. One belt is plenty for power transfer.

I love your work you do a great job just FYI you can’t bend a v belt backwards it will always break if your going to do that get double sided v belt it can take the stress

That shift spinning in the bracket is NO BUENO - you need to weld a washer with a flat ground on the outside so it's D-shaped to the end of the shaft, then weld a piece of square keystock to the bracket to keep that shaft from spinning in the mild steel Idler holder and woggling out the holes kiddo

Yes, I agree. I noticed that, too.

Why do you think the belt broke? Can we see the failed one?

@woodandmetalshoptime8048 3 ай бұрын

I stalled the machine with the blade and that's when it happened, the belt shredded. Since the belts aren't "matched" one belt carries most of the load. I use two belts for redundancy, not for power transfer. One belt is enough for power transfer, the second belt is for just this situation.
