You are correct if it is a clean break it may not have any metal but still worth a...

    JD 344H Wheel Loader - Back wheels will not engage.

    Something broke, the transfer case mounts directly to the rear axle and is direct drive to the rear(no drive shaft) or no disconnect as far as I know. So I would guess something broke in the transfer case or in the rear axle. I would drain/check oil in rear axle and transfer case for metal.

    Volvo L90G Fuel rail PSI at idle.

    Does anyone know what the rail pressure should be at idle? This spec is not in Prosis. Mine is around 11000-12000 PSI. That seems high for idle.

    1995 Michigan Volvo L50 no power to fuses

    OK, I only have a wiring diagram for a L50B so this information has to be taken with caution, however I have found Volvo to keep things constant between close models. Power for fuses 1-6 go first through the Ign switch, If it has multiple wires you may have hooked them up incorrectly, then goes...

    Mack AI 400 Extended Crank Time

    Put jumpers or a booster on it and see if it fires right up, if so put new batteries in it. I had one do this to me and batteries and crank speed seemed fine however when cranking ECM voltage must have been dropping to low to activate the injectors. I replaced the batteries and it cured the problem.
