Model 44 hydraulic unit question

On tractor applications they generally came with 25 and 37gpm pumps.
Never have heard of flow as low as 9 gpm. They do use "Vickers" pump cartridges so they may of had one with that flow option.

I'm curious if Cat supplied these units for special applications like this, or if they were ordered out of the parts book, or if they were taken off an old machine. If there are no machine applications with a 9gpm pump, I guess maybe Cat supplied them. The boat has cat engines and gen sets too. I'm supposed to go look at it this week. I'll have to poke around a little bit.

Can you post a picture of the tag on the #44 unit ?

Get lots of pictures, particularly of tags and general arrangements

What is the name of the boat, I have seen the same set up on a boat.

I'll get some pictures. I'm not sure what the name of the boat is, I haven't seen it yet. It's in Hermann MO now.

I used to see tow boats set up like that in Louisana back in 1958. That seemed to be the standard steer set up back then. The boat in Hermann must be that old. What engines does it have?? Bill Walter ,Parkville, MO.

All I have is the hydraulic unit info right now. I'll try to post some pictures when I go look at it this week. Interesting that this is a "common" set up, but I guess if Cat was supplying the engines it makes sense. I don't know the age of the boat yet, It's being rebuilt now, so I know its been around a while.

Is it the Hermann Sand and Gravels boat?
