Okay I figured out that my HD6G has a AC 6000 engine in it, and a wet clutch. The clutch was both slipping and getting stuck for the last hour the "professional heavy equipment operator" was running her.  Now the clutch does not engage at all when the lever is pulled back.An inspection of the inside of the clutch housing (through the flat plate on operator's right of the housing) shows zero oil, I assume due to a leak somewhere shortly before the clutch failed. I can not smell any kind of "burnt" smell from the housing. Does anyone have any ideas on what to do after I fix the leak? Is it wishful thinking to hope that fluid and new filter will get her up and going? I don't want to fill her with oil if odds are that she needs to come apart anyway. |

Doubt if a fresh charge of oil will solve problems you mentioned. At best, it would show you if the small engine driven circulation pump is still doing its job, but after running dry, thats unlikely. The clutch assemblies can be removed once driveshaft is removed. Its then a strip down procedure, checking friction and steel plates for any warping which occurs when run dry. |

Just to be clear, she is not "stuck" as in the clutch is stuck engaged. I have the opposite problem. With the engine running and the master clutch lever pulled back into the engaged position she will not move. Not sure if that means that I am any better off. Im just hoping that it does. Leo |

I am coming to the conclusion that these days "professional operator" usually means that you know how to climb into an air conditioned cab, turn on the satellite radio and work a joystick as if you were playing Nintendo. Gauges are a novelty to these new guys. They have never seen one before because they were taken out years ago after exasperated manufactures gave up on the idea that a human could pay attention to anything in that cab. This is why modern machines just shut themselves down and then give the operator a warning (in a sexy British accent no less) to please exit the cab before the maximum OSHA limit of 71°F is reached in the cab. Before he even moves toward the door she (the computer) has already informed her factory of what the problem is and which parts she is going to need so that the sales department can schedule an outrageously expensive onsight service call. Perhaps I am just a bit jaded after this guy charged me $50/hr to come damage my machine. His boss gave him a good reference, and I verified that we was CAT trained and certified as a Dozer operator. That don't mean nothing I guess. He didn't tip it over is about all I can say for the guy. I am afraid that the days of real "Dozer Men" are long gone. The visceral connections that those men had with thier machines allowed them to feel and hear the slighest vibration and what it meant before anything blew up. Today the only connection between man and machine, if any, is the operator's butt against the vinyl seat. Well I guess its time to take several days off to fix her, and then several more to do the work I was hopping to pay a pro to do. Oh Well, live and learn I guess. |

Now that the machines electronicaly log everything that the driver does, and the conditions under which they did it the factory can often deny a warranty claim which should help make owners more liable for damage they caused. Many owners of BMW cars have no idea that the car has a data link and updates the factory whenever it senses an abuse or fault. It does this without the owners consent, and all the high end models do it. Of course these big machines also cut back power when they sence any condition out of specification, as well so damage should be minimized. |

Yes, there solution when hearing a strange noise is turn the radio up louder so that they can't hear the noise. ------------- Jack of all trades, master of none |
