Moving along with my latest project, a Case 646 with backhoe. She’s getting a full restoration. The frame was shot so ended up with a donor frame from Don Pressing. Photos below. I’ll update as I progress with the project.
Excellent! Nice to see some photos of a bare frame of a 600 series. These should be posted somewhere for posterity showing what/how a "loader ready" frame is made for those that looking to build one!
I'm in Connecticut. The paint work is done inside, but the build is happening outdoors as weather permits. I have all the parts in plastic totes awaiting refresh. They are gone through inside (gaskets, o rings, paint, etc) then installed to the machine outside.
update on the project. Steering system has been rebuilt. I adapted the shaft to accept the standard MTD type wheels. It’s as simple as drilling and pinning the splined adapter from any MTD machine.
I’ve been busy. Installed the metal hydraulic lines for the loader control and battery box. Need to spend some time under the machine to run the larger lines next.
most of the rear of the machine has been painted, just waiting for installation at this point.
It’s been about a month since my last update so it’s time. I’ll do a few so bear with me.
First off I refreshed the Onan CCK. I was told by the previous owner that this motor was just recently rebuilt but I wanted to see for myself. He wasn’t lying! I could read the numbers in the bearings clear as day! No wear at all. The motor was tight and fresh. I honed and replaced the rings, lapped and installed the valves and adjusted.
I’m now slowly refreshing the appearance and assembling it.
Also did some work on the hydraulic cylinders. The lift cylinders came apart easily, replaced all the seals, I’m currently waiting for a nice day to paint the cylinders before I install the pistons again.
The dump cylinder was a chore until I realized I could push the top down past the retaining ring to easily remove it. (Take note and learn from my mistake there, I wasted waaaay to much time struggling with getting the spring clip out prior to pushing it down and easily removing it.)
There was a little bit of pitting on the piston, I did my best to polish it out, there isn’t any rough edges now so the seals should survive!

If you're real careful you can even use the cylinder itself to push that in if it's stuck by propping something between the gland and the end of the rod and retracting the cylinder CAREFULLY to push on it. I'm not sure how it works because in my head the piston and the gland have the same surface area and the cylinder would basically not exert any force, but i did it and it moved it a bit. Not my first choice but if it comes to swinging a hammer to get it moving it starts looking like a less bad option. Just have to be careful to avoid damaging the rod, whichever way one goes.
Nice work.
I’m using a single stage enamel paint. As far as methods, nothing out of the ordinary. Just like anything else, prep is key.
I sandblast to bare metal, apply a primer (red oxide primer) then scuff and paint. I believe both are Majic brand (tractor supply co). I’ve read a lot of people knock it but if applied with hardener and mixed according to manufacturers instructions I’ve had no issues using that line of product.
