If it aint broke, don’t fix, or never throw anything away.
Kuhn 2135 had its first outing yesterday, has been in the workshop for the bearings in one of the net rollers to be replaced after one side lost its shield and kept grabbing and tearing the net the end of last season.
Putting it all back together, noticed that the drive belt was a little ripe so replaced with a new one.
First 2 bales popped out without a problem, but then the net would start to feed into the chamber shortly after starting the next bale.
1/2 hour later, came to the conclusion that the new drive belt was the issue, with the baler running empty, I stood looking at the drive belt, which should run slack unless feeding the net in, and noticed that the rubber drive roller would now and again move slightly, the belt under no tension should slip over this pulley, which meant it was feeding net into the chamber, and when a long enough length of net was in the chamber and enough grass to catch the net, off it went.
Mrs GMB was bringing coffee and chocolate, so I sent her into the workshop to retrieve the old belt which I had carefully packed away.
Off with the new belt, same numbers as old one, measured against the old belt, old belt was a tad bigger.
On with the old belt, perfect for the rest of the day.
The question is, had I not kept the old belt, is there any adjustment in the system to allow for the new, unworn belt?
The large main drive pulley comes apart and the parts book shows 2 shims between the two halves of the pulley, the only thing I can think of is to increase the shim thickness to allow the new belt to sit lower in the pulley, thus giving some slack in the new belt.
