| Hey yall just got back up from flordia. Put my brother in law on my ol gal and now the clutch won't engage. I figured he knew what he was doing since he runs a crew of asfault guys. I rode with him at first and he got it I thought. After an hour or so he messed her up. When I pulled the floorboard panels up I noticed a rod on the right side that moves with the clutch handle bit it's not connected to anything and I can't find any information on it. Figured I'd see whatbuall think before opening her up and adjusting the clutch on her. Please help. |

| THE rod should be connect to a other rod with a boot on and she is going in the front transmission shifting housing and this rod is loock the transmission in gear when the cluch is angaged and this should affect the cluch. |

| The master need 25lbs to 30 lbs maximum and the cluch should angage with a distinct over-center snap (engine stop) |

I am lost as to what is not working. There is rod that locks the shifter up when the clutch is engaged. Unless that is released it should not come out of gear. Is that the trouble?

| It acts like it's not engaging the clutch when the lever is pulled back. But when I checked the pull it was just over 35 pounds. The floorboards are out and watching the levers it looks like it's working. Bit it won't go in gear when running just grinds |

When you pull that handle back you are engaging the main clutch and if transmission is in neutral, it is going to grind if you attempt to put the transmission into a gear. If that rod mentioned were operating correctly, you would not be able to move that shifter with the clutch engaged. With the handle pushed forward, the clutch is released. You can now shift gears in the transmission. With the transmission in a selected gear position, and the handle pulled back engaging the clutch, the tractor should move and you should not be able to move the transmission shift lever. If I am reading your postings correctly, the rod mentioned is not connected to the shift mechanism and laying loose. When you push the clutch lever forward, the main clutch is not releasing and continues to spin the transmission? This is either a warped clutch disc, pressure plate, (clutch cover) or sections of the friction material have broken free from their mountings and are binding between the flywheel, and pressure plate of the engine causing a frictional "drag". If clutch adjustment does not solve the issue, clutch apparatus replacement is your next option along with bushings, and any linkage points involved. From this vantage point I would say it is probably time to replace the clutch assembly. ------------- That's All Folks! |

| General Gear out of Boise Id has parts books and service manuals on line for most older crawlers. They have HD 6 books as just looked at them. They have been the go to for steering clutch parts for a long time. Looks as if they may have the wear parts for the master clutch as well. |

| I've owned and driven the machine for the last 2 years with no problem like arising. I did read that letting her set with the clutch disengaged for a long period of time will cause the disk to stick to the flywheel. I did start her in low gear and drove to a tree put her in full throttle against the tree. All she did was dig a big hole from the tracks. |

| Well im stuck now. Worked a li l on my ol gal this morning and didn't end well. I tried adjusting the main clutch by a few turns and now I aint got enough strength to pull the lever back. I was trying going to get it down to 30lbs but somehow ending up making it worse. I know to add more pressure turn it clockwise so I turned it counterclockwise. Any ideas would be helpful please. |

| I have just looked it up and counterclockwise tightens it. Also if you need to buy parts it should be an Alburn clutch. Good luck I hope you get it sorted. |

Ummm... please define 'a few turns'. This type of clutch typically needs only a few 'notches' of movement on the adjuster gizmo.

| The HD5-HD6 use a AUBURN and some use ROCKFORD cluch and when these are to much adjusted you need to desajusted and try to readjusted 2 or teeth and try to angaged the cluch lever until you have a good snap and am still have some parts for. |

| According the the operating and field maintenance it says to go clockwise to tighten. It's an original book not a remake. Just looked again and it clearly says to turn clockwise. I would think it's the same as all equipment the direction would be from the drivers seat. |

| I know where i screwed up when I was working on her it was late in the night after a long day. After adjusting her i forgot to lock the plata in place and I started the engine and tried the clutch. I believe that's what tightened her down so tight. |

I adjusted the clutch on my Son-in-law's HD5G last summer, it has the same clutch as yours. It only required two notches to get it tight again, but since yours was run without having the adjustment locked in place, all bets are off  Clockwise while sitting in the operator's seat tightens the clutch.

| I've been driving the inner ring clockwise for a while now its slow going for me since it's hard to get in there. That would make the outter notched ring go on the counterclockwise direction to loosen is this correct? |

| This is a AUBURN cluch on photo and you should have a ROCKFORD cluch and it could be the tread on adjusting ring or the backplate treade are bad or it could be the 3 cam bearing are bad worn |

The only unit I have experience with is the Auburn clutch so I'm not much help. The Auburn clutch has ramps that make it easy to decipher, but the Rockford clutch isn't readily discernible from the drawing. |

| If you can not adjusted your cluch it could be the cams bearings ,links and pines,traide on adjusting ring,brooking springs you better pull out the cluch assambly and you will see the probleme. |
