The encoder is 9 mm thick. A CIM pinion (VP) is 19 mm long. The CIM shaft extension is ~31 mm past the pilot boss. So the encoder will fit between pilot and pinion, without pushing the pinion past the end of the shaft. However, it will be about 1/4 to 3/8 inch further from the front motor bearing than teams would typically put it, increasing the bending moment. In applications where bending a CIM shaft is foreseeable (I think a 254 mentor has posted about seeing that), this method of encoder mounting will increase the risk of bending the shaft.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
