Well, the day I hired a guy with a truck and trailer to haul the JD 400 backhoe I took on trade for work I completed at a home, the backhoe decided it wasn't going to start for anything!
I finally hauled it home myself after 5 hours loading it on my trailer by myself with chains, straps, come alongs, and chain falls.
fast forward a week and I have the injector pump off. (The shear screws on the drive gear sheared and did their job thankfully).
There is a 1/4-32 flat head machine screw that holds the "leaf spring" to the rotor inside the injection pump. Apparently fatigue caused the head to separate from the threads.
I carefully used my Dremel and was successful in slotting the remainder of the threads still in the rotor and with some heat, was able to remove the threads.
The rotor is high strength carbon steel it appears, so drilling and tapping to fit a 5/16-28 is out of the question.
I've tried emailing a few people that have posted years ago anything about the CDC pump in hopes someone has one for parts.
If anyone has a spare CDC pump for parts and is willing to either sell it to me or remove the one screw I am looking for, I will be an interested buyer.
Please assist me if you can. I have scoured the Internet looking for a 1/4-32 screw to no avail.
I'm hopeful I may be able to keep my tractor running by using this forum.
