Conveyor stopped conveying.
Pump is working cylinder. Motor is not turning.
Inspection shows alignment is off and metal filings by motor/shaft connection which is simply a keyed slip collar over motor shaft and top drum shaft.
I put a pipe wrench on the connector and rotated it to reveal the set screws. They were loose. 1" motor shaft twisted off easily when coupler rotated, very easily.
It has worked for ten years but two things:
One is that the top drum shaft has been replaced due to tipping backwards and hitting the ground, bending it at the drum hub. The motor shaft may indicate this, as a weathered spot at the edge of the break.
Second: The mounting bracket seems to twist/tilt sideways to the shaft, being a receiver tube in a tube to allow for belt tensioning. The connecting collar would seem to hold the hydraulic motor in line, and the mounting bracket in a horizontal position. On it's own, disconnected from the shaft, the mount tilts considerably.
I'll be going to a hydraulic shop in the morning with the motor and coupler.
Last winter I bought a cylinder from Built-Rite, the conveyor manufacturer, to replace the hand crank up/down. It works well, but I had to have fab work done to make the mount work. I'll be asking tomorrow about a counter balance valve also as I never followed through on that. After sitting for a week it bleeds down completely, within inches of the Posch drums on the turn table. There is no way to pin it in position as is, like some other designs have.
Anyway, I'm down till it's fixed.
