Hi Don; The original wheels were held on the shaft by two roll pins that
are
pressed into holes drilled in the hub/shaft. The hubs are a snug fit, but
should go on the 7/8 inch shaft without extreme difficulty. If you use the
hold drilled in the fitting on the other end of the shaft, which the
universal joint is attached to, to obtain the correct alignment, the new
control wheels can be installed on the shafts while they are outside the
aircraft. The holes for the roll pins are drilled from the bottom of the
hub,
one in the front and one in the rear. They do not quite come through the
hub
on the top side. By using a roll pin, you can compress it ever so slightly
to
get it started in the hole, and then push/drive it home.
I do not remember the PN for the roll pins, but I can look it up if
you desire. I believe they are shown in the original parts manual with the
control wheels and hubs.
