What in the heck is wrong with JCB parts book?

I have a 1995 JCB 214 series 2 backhoe. Serial 3 SLP214CSE0433511 I need a 45mmX330mm pin for the dipper ram (rod end). I had the dipper cylinder rebuilt and am replacing the pins and bushings. I have all the proper bushings and seals, but the rod end takes a 45mmX330mm pin. I have a parts book and it always points to a 50mm pin. THIS WILL NOT WORK!!!!!!!!!!! The seals and bushings are 45mm and already installed. They fit perfectly as does my old pin.
