I didn't find it near as difficult as he did. One thing I did different
was order the cable connector and pig tail to replace the terminal
strip. I did use a bit more grease (White Lithium) than recommended
but it held the bearing races in place. As I was able to turn the
rotator I ran it to the end of rotation. It doesn't matter which end,
just remember which one<:-)) I also took a black felt marker and drew a
line from the top to the bottom of the rotator. I doubt you'll find the
bearings any cheaper any where else. Our local hardware had them in bulk
for about twice the price.
