So I ended up replacing the hydraulic pump. I went with a pump from Grainger. Item #4F667. It was a direct bolt on swap (unsure if stock lovejoy would work as mine wasn’t stock). Works great, very happy with it.
The only problem now is it seems to be running real rich all of a sudden. I have a feeling my float no longer floats. I’ll have to break it apart and see.
Well, beyond the running rich issue,,
The work you're doing at getting your 646 backhoe back to looking new is awesome. I certainly have an appreciation of what it's like to paint some of those items that are cumbersome and incredibly heavy to manipulate into getting things painted. Well done!
I'm not. Actually i'm using the Magic Paints Case Power Yellow. Even with everyone crapping all over their product line in the forums I've found that as long as the machine is prepped correctly and the paint is mixed per instruction (using the hardener) it works great and holds up well.
I painted my last machine (648) with two paint products as I ran out of the first and couldn't find anymore of it when I was almost done. The hood was done with Magic paints and the rest was done with another manufacturer (Tallmans? maybe). The hood is still bright and shiny whereas the rest of the tractor has faded a little. At the end of the day I just wanted a good starting point and the metal to be protected, it's an added bonus that it looks good
Looks great! Lots of respect for dealing with the extra cylinders, plumbing and rigging of the backhoe. My CCK was running way rich at first and the float adjustment seemed to help. The rubber float has a fairly large gap specified in comparison to what you might be used to seeing for metal floats.
