The first step in identifying a suitable replacement PTO assembly or component parts is to determine the "Series" (and "Type" where applicable) of the PTO shaft. The most common styles of PTO shafts are often referred to as "German" or "Italian" style.

You can identify the series/type of a PTO shaft by looking at the Shaft Profile of the inner and outer tubes and cross reference that with the dimensions of the universal joint (measurements AØ and A) used. We will select the required length of the shaft in a later step.
