Chewing belts.

Another update on the Case 224 belt flipping. Cut the grass again with the tractor, and the belt did not flip. So I think it’s fixed.

So an update. I believe I have it fixed. Cut the grass here at home with it yesterday and the belt did not flip. Long story. Short story is, I found that the right side mule drive pulley was back to far when the belt was tightened up. So the belt was not entering the pto pulley straight on and the would not slip into the pto pulley properly. So the pto pulley would catch the belt and flip it. Once going in straight the belt would not flip. Sooo, what I did was, I took the 70” belt off and put on a 69” belt. This allowed the belt to be tightened and keep the pulley forward enough to have the belt going into the pto pulley straight. How I found this was, I took a slow motion video of the belt flipping. Then looked at the stills of the video. It showed the belt starting to flip. So that gave me information where to look.
Any way, for now it works, why it worked for two years before with no trouble I don’t know.
Thanks for following along. Hopefully I explained that well enough so you get the idea. Tractor does not have some original parts so hard to figure out.

I am wondering about generic belt sizing . The original belt may have been right on the edge so that when worn flipped . Then when a new belt "of the same size " was actually a little large in size and flipped right away . A generic belt belt can range as much as 1.5 inches from brand to brand , year to and lot to lot from same brand . Even the width can vary as much as an 1/8" . A lot of the stuff I work on , parts are NLA so I have measure and shop around . I have seen "1/2" belts" as narrow as 7/16" and as wide as 9/16". but are usually between 12mm and 13 mm 12.mm being same as 1/2" . I always measure the OC (outside curcomfrance ) my self because a 70" belt could be 70.6" and add in a little wear on all the pulleys were the belt runs and then it is too long . So putting on a 69" belt that is more than likely 69" and change makes up for the true 70" with new pulleys the machine needed when new .
Sorry I am late to the party with this just occurred to me .

It’s very true what you say there Dave. I’m thinking I could use a 68” belt the next tie I need one.
