Coupler keeps slipping back on Motor/Pump
Coupler keeps slipping back on Motor/Pump
(OP)
I am at wits end. I have a baler with an electric motor that drives a hydraulic pump. But. The Couplings keep slipping away from each other. Sometimes its the Motor side sometimes its the pump side. I have replaced Both Couplings and the buffer. Locktited the Set screws but it keeps happening. Any suggestions?

Is the coupling rated for the torque it is transmitting?

I love to hate balers.

Sometimes there is a setscrew on the key and sometimes another setscrew on the shaft.
If you have a setscrew directly on the shaft, consider dimpling the shaft at the position the setscrew will engage.

Here's an old school alignment procedure that may help:
Fix both coupling flanges on the shafts.
Leave the drive elements out of the coupling for now. Find something to use as a spacer between the coupling flanges.
Possibly a piece of key stock. You want about 40 or 40 thousands of an inch clearance between the spacer and the coupling flanges.
Now insert the spacer at one side of the couplings and measure the clearance with a set of feeler gauges.
Rotate the coupling halves about 15 or 20 degrees and recheck the clearances at the same place on the coupling halves. The clearances should be equal.
It helps to put a mark across the coupling flanges so as to always measure at the same place on the flanges as they are turned.
