HP LaserJet 4V Fusing Assembly Kit (from this site) for my HP 4V. I installed the fuser as instructed (via the video) and reassembled the printer. As the printer was warming up it started to make a bad sound, like a gear skipping. I quickly turned the printer off and dug back in. As far as I can tell, I assembled everything correctly. The only thing that seems odd is that it is very hard to rotate the gear that rotates the fuser roller. If I remove the black roller that presses up against the fuser roller, then the fuser roller rotates easily. It seems like this roller is pressing to hard agains the fuser roller. I inspected all the parts and everything seems in order and located correctly. Does anybody have any ideas what might be going wrong? How hard should the fuser roller be to turn?
On another note, the kit I purchased above only came with the fuser roller. It did not have any of the other parts (new fingers, new black roller) mentioned in the video. Is this a change since the video was made or did I get sent the wrong kit?
Any advice is greatly appreciated.

The only thing that comes in the kit is the fuser roller which normally is the only thing that fails. The video is intended as an all purpose video that can be used in case someone needs to replace any other parts of the fuser. There really isn't any way to diagnose what is wrong without actually seeing the fuser since this is a problem that you somehow input into the fuser. It's not something that occurs normally. About the only thing that I can suggest is that you reverse the whole procedure and do it again.
