Look, I know I'm going to get laughed at, but is there any way there's a smart company out there that has created an electric version of the fuel pump for a Case 580B backhoe?
Mine is about a 1973-75 machine, Serial# 8721107 making it a freak year and or serial number. Book reads it to be a 1972-74, but all the books I got with the machine 15 years ago start at 74-76. Oh well, it's been the love of my life! Had it longer than any man, lol.
OK, so the fuel pump;

It took a strange and awesome turn while I was working the driveway hard, but slow and careful. It kinda sputtered, I quickly grabbed some fuel and put in 2 clean gallons, thinking it may have gotten low. I did a ton of repair work to Casey over the past few months, but as the days got shorter this fall and I "had to" get the ball rolling for major tree and driveway work, AND I decided not to change the fuel filters. That sounds dumb, but I really hadn't put that many hours on it when the steering cylinders went to the south end of the planet along with the outriggers, lift, and stabilizer cylinders 2 maybe 3 years ago. I was still able to start it, move it around regularly, but wouldn't use it until I was sure dirt wouldn't go backwards into the hydraulic system. Pretty much fixed, no major leaks, and moved onto the work at hand.
I moved & piled up at least 4 yards of old gravel and regraded the entire driveway with no problems other than the hoe wouldn't lock back in. I then noticed a cylinder had a seal on inside out from a local repair shop 12 years ago...grrr So, got it tore apart and back together pretty fast with my new found skills by yard lights. That was at least a week before the fuel pump issue. OK, so moving towards the last evening I used Casey. I worked just until after dark, cooler weather but still above 32, even after the new fuel was in. Didn't seem to have any real issues, just a little punky. Luckily, planning ahead as a person does, I left the bucket full so I could spread it come daylight next day. Nay nay, found another more extreme house problem to address 1st. It was about 2 PM when I got back to the "final" bucket of gravel. No go, OK, it's always needed starter fluid to start in cooler weather, and the battery is weak, but if it runs all day, will hold a charge until it sits for 3.
I got out the battery jump charger, a new can of starter fluid, and it would turn over, and mostly start and then stop. I tried and tried, thinking it was bad fuel, so I changed the filters, added chemicals to address bad fuel, and some in the oil, incase it was sluggish. (seafoam). I then set out to clear all the fuel lines of any potential gunk, blew air backwards from the tank through the return lines (used a plastic bag and an air nozzle wand at the cap). Nope. OK, back to Youtube videos for steps of action. Took supply lines off at pump, cleaned and blew them out. Finally carefully, and panicked like, removed top the cover. the small spring from inside the double retainer, inside the governor spring was in the bottom and rusted.
I watched another 20 times, related videos that showed the pump assembly actions. I used a tiny o ring pick hook tool and got it out. 1st I assembled it wrong, and then did it correct. I did not remove the cam, or any other part of the pump, but slid the spring and the evil spring assy with the retainer & mini spring in it, under it. It was a PITA, but it worked. Reassembled all, and still no fuel in bowl. Poop. Lid off again, and it seems that the cam spring assembly that I put back humps up and doesn't return to flat correctly when manually messing with it. The delicate assembly that sits in the tiny front well towards the engine that has the blade pin-roller may be damaged? I don't know. Nothing leaks, I've used a brake vacuum pump pot tool to completely remove any debris from the interior of the pump and lines and flushed. I even tried filling the bowl and hoped it would somehow prime the situation. Nope.
Rebuild videos show great mechanics that failed at rebuilding this model....horribly. I'm pretty good, but not so sure I can do it better than those guys, or all during winter here in central WA.
My thoughts are then towards how about an Electric version? At least to get me through until spring? Although Casey is happy to sit dead center of the driveway of my 1/2 acre city lot, right outside my house windows, for months...I have to move it and obviously unload the 1 1/2 yard buck of gravel. I barely fit the service truck (carpenter stuff) past it with ratchet straps pulling the outriggers in as far as they would go! Trailers? No way! They're all still out front waiting to be put away.
Can anyone give me guidance, and or confidence to fix this stupid situation? From what I can tell, a rebuild is $2000 + $800 core ( no disassembly allowed), shipping, taxes, etc. WOW $3K is hard to come by these days for me. And as a final note, "how do I find the correct piston revolution line up" to remove it in the 1st place...by my self? This doesn't exactly have a tilt hood!
Thanks a Million,
