| The engine clutch on my HD-5 has stuck after sitting for a couple weeks. I've tried driving around with the clutch released as well as running into a tree, neither helped. Any other suggestions? |

Open the inspection plate on side of bellhousing and observe the action of the clutch. Lat time i had that happen to me - one of the fingers from the throwout sleeve had come loose and did not allow the pressure plate to disengage. As the clutch is a overcenter clutch the sleeve needs to snap back and forth - when clutch is engaged or released there has to be free play in the lever - IF all else fails - loosen adjusting bolt and back off the pressure plate a couple notches . Without looking into the clutch housing to see actual movement or problem it's hard to diagnose . ------------- Faith isn't a jump in the dark. It is a walk in the light.

| Did take the cover off, couldn't tell if the pres. plate was moving but had about 1 1/2 inch movement on the driveshaft brake. Freeplay at both ends of the clutch lever stroke. Sleeve was greased when I used it last. |

You can feel the resistance of the overcenter clutch as well as hear it snap in or snap out . If you have 1 1/2" clearance on the clutch brake - something is wrong . Inspect the linkage between the the throw uput sleeve and the pressure plate, be sure all the links are there and all the pins are in the links . Another possibility is IF the facing on the clutch has came loose and wedged into area of disc and clutch. I have seen where the splines have been bad enough that clutch disc hangs up also but that will in most cases shake loose.

| Thanks for the input, as far as I can tell everything operates the same as when the clutch was functioning it just won't shake lose. As jobs are piling up in the shop and field it'll be a few days before I can devote much time to my own projects. I'll get back to you if anything develops. |

| Once the clutch on my HD6 adjusted itself too tight so that it would not disengage. Can you feel the clutch lever snap over center? Try adjusting the clutch. |

Got the bell-housing and clutch off of the HD-5 this morning, turns out the clutch basket was packed FULL of dirt and wouldn't allow the press. plate to move back. With a good cleaning everything should be back to normal. |
