Case/Davis trencher backhoe

Trucks, cars, boats, motorcycles, snowmobiles. If you can drive it and it has an engine but it's not a tractor, it fits here.

Started assembly today. Not that everything is done but the major parts are and I'll deal with smaller issues as they come up during assembly.

For instance, after setting the swing cylinder in, it occurred to me that the middle part with the rack can rotate and that's most likely how the lower side of the rack teeth got damaged. Bingo. I was wondering for a while why there is a rail on the back side. Turns out that there is a guide for the rail, to keep the rack from rotating in the cylinders.

The guide in the parts manual circled in red was sheared off the bolt. I made a guide from a new bolt with 1/8 plate welded above and below the bolt head.

Also spent time cleaning all the pins with the wire wheel. That's labour intensive but they were in really bad shape, rusty.

Then all the backhoe arm bores where the pins go got cleaned up with the electrical die grinder and 1" flap wheel. @RoamingGnome, I must thank you again, that tool you pointed me to from PA made the job a breeze.


@JSinMO , thanks for following along, it does feel that way for me, I'm starting to see the light at the end of the tunnel. Of course major set backs can still happen. That being said I have to restrain myself as I feel like working on it all the time and get it done quickly. As it is we have Monday off and until Monday I won't touch it,
