Default Standard Cirrus C-Hook

Randy,
It will take some glass work to swap out both sides of your elevator
drive, ie change early SH 14.15mm connections to later SH 19mm drive
mechanisms. As with any "used parts", they must be inspected by a
qualified person to determine damage, wear and corrosion. These parts
have been stored in my barn for about 20 years, ever sence their
rather spectacular 'last flight'. You could change to a "used"
elevator with 19mm drive, but that would be over-kill to solve a
rather simple problem. The C-hook is nothing more than a 10mm bolt
with the "C" fitting welded on top of it. Recommend you take both new
and old fittings to a good machine shop and have them cut the C
portion off both and then weld the new 10mm bolt section onto the old
14.15 C-hook. Before removing the C-hook from your Cirrus, be sure to
measure the exact distance from the top of the push-rod to the bottom
of the C in the C-hook. When installing the new part, screw it in
until the distance is exactly the same. Then tighten the jam-nut and
check the elevator throw against the FM/MM.
Have fun,
JJ
