The clutch is not real difficult to replace. The only thing is to make sure it is not installed 180 degress out of phase. The clutch can be accessed from the rear behind the engine board which must be removed as well as the cleaning board, its a small assy directly behind the clutch. Remove the imaging unit(iu) to access the shaft attatched to the clutch. The shaft sits directly in front of the iu and has 2 black lobes/cams on it. Remove the e-clip on the front of the shaft and slide the bushing off then slide the rear bushing forward and you should be able to remove the entire shaft with the clutch still attached out through the rear. Remove the clutch and make note that the raised catches on the clutch should roughly line up with the cams on the shaft, if not this is where the 180 phase shift will cause problems. Be careful of the pin in the shaft when the clutch is removed that it does not get lost, this locks the clutch in position. Once the clutch is replaced on the shaft you can re-install the shaft assy. As a note the cleaning board is what ativates the clutch and i have not seen these go bad very often but keep in mind the possibility is there. Hope this helps, its been awile since I replaced one.
