I got these. They are a little long, they stick out about 1.5 to 2 mm. I use that as a quick check to make sure they are not backing out. I also use Loctite 242 on them.
How do you align the pulleys with the idlers and belts when you use these motor/pulley sets?
@LarryM they come pressed on at the right distance.
yup, that’s exactly what I mentioned a few days ago on this thread, it’s a common problem. glad you were able to figure it out!
