So i tossed all 4 injectors into the parts washer and let em soak for a few days (ok maybe a week)  From there i began the process of disassembling and cleaning them:   Pulling the nozzle apart, you can see there was still grime and buildup inside them
 All 4 injectors stripped down   You can see that the 4 individual injectors have worn into each other differently, so ive made a conscious effort not to mix and match parts between each injector  After full cleaning (and testing each nozzle to see if all 4 ports in each nozzle spray), i have begun the reassembly process:  ...and all 4 are now done!  So nothing left to do now, but get these things slapped in, get the fuel system bled again, and it should finally roar to life! Here's hoping! Mission Fail  Got the injection pump in  Bled the system to the injectors but couldn't get it to fire on diesel, only ether. Pulled the gas tank off to get to the injectors. Kinda grimy down there  We had fuel to the injectors, and thru the return line back to the tank so I'm going to assume the injectors are gunked up and not spraying. Injectors out:  I'm probably going to bring them to work tonight, throw them in the parts washer and let them soak all weekend, then maybe I'll break em down during the week and see about rebuilding them. Working on the injection pump for the Massey  Picked up a cheap seal kit  Pulled the end cap off and disassembled what I assume is a pressure relief   Found some chunks in the screen  I popped the cap off the top. Not sure what I was expecting to find, but it wasn't this  Overall the pump is fairly clean. I don't think I'm going to dig in much deeper. I suspect the mechanism for the shutoff was stuck, so I'm thinking that's why I couldn't get it to pump fuel. With noting really left to do i slapped it back together:  I rigged up a primitive fuel supply, and cranked the pump over with a cordless drill. It works!  Just gravity feeding it 100% Marvels. It's spitting out all 4 injector ports. Not very much coming out, but I could see a ton of air coming out the return port, so assuming it's not bled yet. Not sure how long it takes to bleed, so I'll probably just sort that one out when it's on the tractor. Figure it'll probably bleed faster if it's being supplied fuel from a pump as opposed to just gravity feeding down some tubing. Mission Fail. We're 0/2 here.  We removed the fuel lines to inspect before installing the new fuel pump. All lines were clear except for the one between the tank and the pump, so we cleaned that and installed the new fuel pump.  Bled the line + pump. Bled the next line + first fuel filter Bled next line + second fuel filter Bled next line + injection pump Got fuel to the feed and return so we threw a battery in it, and I disconnected all 4 injector lines. Cranked the engine over and nothing. Can't get even one drop of fuel out of any of the ports. So now the injection pump is on my work bench  Hopefully it's something dumb like varnish in the pump or something, because id rather not rebuild the pump. Its a little overgrown  Theres an old J20 too  Got it dug out, and both fuel filters replaced   The fuel pump was full of gunk, tried (unsuccessfully) to clean it out  Ultimately though? Mission Failure  Never got the fuel pump to work, going to have to order one. Tried winching it up the trailer but the rear right tire won't turn. Even with 2 snatch blocks the winch just wouldn't drag the tractor up the ramps. Looks like there's some kind of roller for mowing, a back blade, a brush hog, and something else in the weeds. Supposedly there's a set of forks for the bucket too. So I guess the new plan is to order a fuel pump, and bring cleaner and an air compressor to try to flush all the fuel lines with hopes we can get it to run. The starter cranks over pretty good, so I think once we get the pump replaced it'll run. it actually had green coolant in the radiator, and the crankcase was full of oil so thats promising.   All I know is, it's a diesel, it hasn't been run in years, looks like it's got a flat tire, there's some attachments, and it's free! Maybe a half hour away. Going to try and get it Thursday. I dunno what it weighs, hoping it's not over 7k. |
