Hello guys. I have a 1974 Case 580B diesel with a wain roy clam shell bucket on the hoe. At some point someone had this bucket installed, it’s great, very usefull, only problem is it keeps drifting open. While digging etc I have to constantly keep closing the bucket. I’ve done a lot of repairs to the machine already for the year that I’ve had it and mostly because I have the service manual to follow. But this is an aftermarket set up so nothing in the manual for it. The piston in the bucket is nice and dry so I don’t think it needs new seals. The three way valve in the cab gets its oil source from the stabilizer valve. How should I proceed in toubleshooting? Relief in the stabilizer valve, seals/o rings in the three way, etc? I’m not really sure. Thanks in advance for the help!
