Just finished my first arm assembly and had extreme difficulty seating the idler shaft and cam gear against motor drive gear. I had to start over with assembly and pound in the idler shaft first to get shaft to seat. After assembling the two arm half’s with belt, cams and gears, it did come together eventually. Seemed way too tight of tolerances or lack there of to work efficiently. Any others had this issue??? Have three more to go but looking for input before preceding. Seems like too much internal tension to work properly.
Yes, you are absolutely not the first person to notice that. First, they are a very tight fit so that is somewhat normal. Second, someone else pointed out that the bolts which attach the motor have a little play in them so if you scoot the motor forward rather than backwards before tightening those the idler gears will fit on more easily
Yeah, that was me. I found that if you did not tighten the motor attachment bolts before dropping in the idler gear (or more accurately, loosened them a little having already tightened them all the way originally 
), the idler gear slides in a lot more easily.

Thanks, that makes sense as I start my second build this morning. I went back and loosened my first build with the motor so hoping that helps when I test. I appreciate the response:-)

hmm, I wonder how many people who have had to up their power limits are really
fighting the motor being too close to the idler instead of other issues?
