I'm a new OC4 Owner with only 3 weeks experience and Im learning fast.
I had a funny thing happen to the loader of my 1956 OC46 Loader. My 22 year old son was operating the machine about 5 feet from the edge of a steep hill. He had a full load in the bucket raised up and ready to dump, when Two of the large bolts that hold the right upper cap on, ripped out. The bucket tilted and the machine lurched a little toward the hill. :D
The caps should definately have long bolts in them .That joint has a lot of pressure on it .

The bolts that ripped out looked original, someone must have changed them. I cut Studs from Truck Axle U-Bolts threaded them all the way down with flat and lock wasers with new locking nuts.
