I am going to have the CAM tensioners replaced on my 2000FXD before Spring, and have talked to the service manager at my local dealer twice about this. He is telling me that replacing the tensioners is at a minimum a 1/2 day project, or at least 4 hours or more. It seems that this is not that time consuming for an experienced mechanic. Is this guy jerking me around or is it really going to take 4 or more hours to replace the CAM tensioners???
