  7. Thank you for the reply. Sorry for the delay. Forty is more than reasonable, but please give me a few days to see if i can locate a blue. I will get back to you assp
  8. Alex thank you at the rate I’m going I think I may have to go with something other than blue. How much are you asking?
  9. Hello gentleman...I am in a desperate search for a BLUE bug deflector TO fit a 1980 U model. I’m on a pretty tight budge,t So please ,your best deal. The one that was on the U model I gave to a friend of a friend paint and they and the bug shield disappeared.
  10. Thank you sir. Thats a huge help. I’ll be back at it tonight 😃
  11. While in the process of replacing the wiring harness, I removed Three air brake valves from the dash. I thought I marked them well, air line placement and so forth; however, ( and this is a tip for others) the paper and ink I used was not water-resistant and i now cant tell well most of the lines go. I have it figured out for the most part as the trailer brake valve and pressure switch is marked differently, but currently there is an open hole that air streams through. So it's obvious I'm missing something. MOst of the info I've found only refers to two valves in the dash. Any help, schematics, drawings pictures- the service manual isn't giving me much guidance either? I'm scratching my head.
  12. whew!! Thank you , you were absolutely right and I was overthinking it!! Batteries just needed a boost!!
  13. thank you sir i have check cleaned and tightened ground wires. I have put the charger on. ( fingers crossed, thats it!) But to clarify, if I omitted the Kyser wiring and possibly not removed a wire, would that affect the crank?
  14. HELLO GENTLEMEN! It looks like I've really done it now. The 1980 U model I've been working on was having intermittent electrical problems and I found that chaffed wires were causing serious issues. For two weeks I attempted to piece fix the harness and finally tore the whole thing out and replaced the wires per the schematic. minus the Kyser shutdown wiring. Now, the engine barely cranks over . Is there something in the scensors that would be telling the engine not to turn? I've read about a jump wire but dont' have enough information to assertain the proper location. Any help or insight would be greatly appreciated the old girl has a job waiting on her. not to mention my pride could use some help!!
  15. hello fellas! Still working on my Dad's 1980 U model. I have everything wired and aired up since the last issue, thanks to every ones's advise and information. This is my current issue, some "one" has messed with the fuel pump, "turned it up". I'm certain this was an unnecessary adjustment as the truck runs worse and throws/blows black soot like she's on fire. What is the proper procedure for adjusting the fuel injection pump? I want to turn it down. The engine is a 237, all stock.
  16. the Pipe was blowing exhaust directly into frame rail. I have a couple pics I’m trying to get uploaded. Please bare with me
  17. Thank you very much. Every bit of info helps. As you’ve stated deflecting exhaust heat is a concern. Any suggestions that will try to keep heat from the goings on in the frame rails? Or do you think that wasn’t necessarily a u model issue -but the lack of proper exhaust piping -which allowed the heat direct access ?? Knowing that will help decide how to proceed in that area Thank you again for your help !!
