Thanks!!
Thanks for the suggestions! I will definitely try that before I get too crazy on the IP.
I went through fuel issue with my rig and had some of the same concerns on my injector pump. I had a small outboard engine fuel tank with a squeeze bulb sitting around so I disconnected the short fuel line between the fuel shut off valve and the fuel strainer and hooked the temp tank up so it gravity fed so that I cut out the fuel tank and its connections as a source of problems. I then used to squeeze bulb to pump up the system. My truck would run and then lose prime. With the squeeze bulb and temporary tank it would run fine for awhile and then lose prime until I squeezed it again. I ended up replacing all the hoses and cut a new strainer gasket, including the hoses hidden on top of the tank. I was warned elsewhere that running the injector pump dry was a very bad thing as it gets its lube from the fuel. In my research Mercedes diesel car owners of that era had similar issue with the plastic fuel lines.
I also just went through a lot of electrical issues (critter ate the electrical harness behind the dash) and the final glitch after repair was that the remote throttle and the hand tool switches didn't work. There is one common 16 amp fuse (one of the few red ones) that supplies the remote throttle, the hand tools and the electric hydraulic cooling fans (and possibly the remote bucket lift?) . It is the first fuse on the left side of the #2 fuse box that is the box on the right if you are looking at it from the front of the truck. I kept loosing the fuse and finally traced it to one of the electric cooling fans which was rusted solid inside from water getting inside the motor. The fans are controlled by a thermal switch so the dead motor wouldn't cook the fuse until I started to run the backhoe for long enough to heat up the oil to the point where the thermal switch snapped. I couldn't locate a spare fan and didn't want to buy the entire cooler that EI has listed (I created a ticket with them regarding just the fan or the motor but they never replied) so I picked up some new 24 V radiator fans on Ebay and built an adaptor plate. I just installed them Saturday and ran the backhoe for three hours with no fuse issues. Not OEM but figure I would rather have new fans than 25 year old fans with a potential design defect. I tried the hand hydraulic pump system previously with no success but expect that fuse issue was making it not work. I pulled the switch Saturday and the pump obviously started and ran and the throttle sped up automatically so it may be worth tracing the fuse back to the switch panel on the back. A "dooh" moment on my part is realizing that its heck of lot easier to work on the fans and wiring with the backhoe raised to the up position.
Good luck, it will be interesting to see if the same issues are popping up with these SEEs
Cool on the rock bits, mine came with all the ones listed on the BOL but no more. I found a cross reference somewhere to the bits, they aren't standard but there are some firms that make bits that match up. I didn't get the chainsaw which is good thing as it doesn't have chainbrake and Kevlar chaps may not stop the blade as it has a lot more torque than a two stroke.
