Dave,

Thanks for the reply. The pump only has the one shaft for PTO hookup. It's quit raining for the time being, so I'll see about getting some pictures of the hoist and pump this afternoon.

And yes, Rowe Trucking was in fact the first place I called, but the parts counter guy had about zero interest in trying to help me identify what kind of hoist this is. The bed has a Rowe emblem on it, so I know that they at least sold the bed. It looks to be newer. The hoist may have been on the truck since it was new. Rowe has been a great resource as I've worked on this truck, but only if you pretty much know exactly what you need when you walk in. If it requires any effort on their part, you might as well forget it. Things have changed since 'ole Claude Rowe died.
