The XTS series has a different trimmer than the XT's and the Big Reds, unless it is the Pre XT model that has the same trimmer as the XT's. The XT's trimmer is a separate knife and a separate selector that can be replaced individually. The XTS has what they refer to as the ACAT. When this unit is replaced, both the knife and selector are replaced as one single unit as they are riveted together. This unit is held on to the trimmer housing block by an e-clip. Removing the entire block is not advisable unless you have the proper knowledge and/or training to get it back into adjustment. The " what I think looks like a fan- small flat circle with some triangles in it" is an e-clip that clips on to a center post to hold the unit in place. Removing this clip is ok to get the knife/selector unit off to clean or replace it, just not the entire housing block. Maybe the tech mis-understood what you telling him as to what you removed. The description you gave at the beginning of this post leads me to believe that you removed the trimmer/knife assembly and not the complete housing assembly. It is always a good idea to take the time to go into the tech-help-parts-section and look at the machine breakdown to see just what is the name of the parts you are trying to describe. Saves a lot of confusion at times.
