I know it can be difficult replacing some parts. The information and pictures you have received are correct for this dispenser. Unfortunately, there are no other instructions. If the new actuator will not fit back in place, first make sure it is the correct part. Unfortunately, without a model number I am unable to provide that specific information. If it is the correct part but it's not fitting, this will be something that has to actually be seen to determine why. A technician may be needed, to see what is taking place. I'm listing a site you can access, to have a tech come out. Here is a link for the website:
