Nagzz4423 13 #1 Posted May 7, 2016 I just put on a new drive belt and mower belt and noticed the side stitching fraying. Is that normal with a new belt? I did clean all the pulleys with a wire brush before the new belt went on. Also, I noticed by pto pull your the belt slightly angles to the right too and is that normal? Pics attached.

gwest_ca-(File Mod) 11,493 #2 Posted May 8, 2016 You should not have any fraying on the belts sides. Something is not right. The mower drive belt is the one with the problem or the transmission drive belt? Garry Share this post Link to post Share on other sites
Nagzz4423 13 #3 Posted May 9, 2016 Garry, it's the mower belt. The belt, which is a oem wheel horse belt has stitching in the middle of it and after mowing the lawn, I noticed that side stitching only is frayed. The belt itself is fine just the side stitching. I followed the proper installation just making sure it's the wearing in process. This is my first tractor and still learning my way around it. Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,493 #4 Posted May 9, 2016 Only the sides of a V-belt should have contact with the pulley. As a belt enters and leaves a pulley groove it slides into it and out of it. Any rust scale on the pulley will damage the belt as it slides over it. I often use a flat file on the sides of the pulley to make sure it is clean. Have also seen a small stone get wedged into the V and that does some serious damage to the belt. If pulley alignment is not correct one side of the belt will suffer because of the extra tension on that side as it slides in and out of the groove. The pulley sides in time can wear to a point where the belt is not wide enough so it ends up contacting the bottom of the V-groove. Bearings in idler pulleys usually get too tight to turn before they get loose but we don't get to see that. If the pulley stops for a second the belt will suffer as it slides over the stopped pulley. After it is shut off feel the pulley and bearing area for an increase in temperature compared to other parts. A hot spot is sure to be a bearing on it's way out.

Nagzz4423 13 #5 Posted May 11, 2016 Garry, I took the deck down and rechecked all pullies and all seem to turn good and I filed and wire brushed all of them as well. I see nothing that would cause the stitching only on the side of the belt to fray. In some parts of the belt, the stitching seems to be the only problem and in some spots you can't see the stitching anymore, almost looks like a solid black belt. Since only the sides touch the belt and that's where the stitching is, you sure it's not normal wear in process? I appreciate all your info and not just on my posts but others.
