    Deutz 1011 miss

    Can't answer your question, but I had this happen to two machines and never figured it out. Replaced lift pump, blew out the line back to the tank, replaced return lines, replaced injectors, replaced timing belt, and replaced the injection pumps. The only thing that helped were the injection...

    Komatsu PC75 swing brake non-functional

    Is it possible the motor is locked to keep the house from spinning? I ask because I don't see a brake mechanism.

    Deutz 1011 miss

    I have a 1990 Gehl 6635 skidsteer. 2400 hours on the machine and I have owned it since 1200 hours. The engine has been very reliable, but it has recently developed a miss. Ironically, this is my second 6635 and the first one developed the same miss at the same hours. I never got that machine...
