| Subject: | AG5B throttle cable |
I had to change a throttle cable on an AG5B this weekend. Changing the th
rottle cable should not take 2 hours.
I've never been a big fan of the AG5B. Too many DUMB design decisions wen
t into the plane. The throttle quadrant is an example. While changing th
e throttle cable, I came up with at least 3 different ways it could have
been done to make it easier to service. But, as with most things on the
AG, maintenance was not a priority.
For those of you who haven't seen it:
All three cables, carb heat, throttle, and mixture are held in place in th
e same bracket with the same piece of aluminum (aluminum retainer). So,
to remove one, the aluminum retainer (that holds all three in place) need
s to be removed. Not a big deal, really, if everything stayed in place.
The bracket that the cables lock into:
The bracket has 3 vertical slots, 1.5 inches apart, 1/2 inches long/deep,
with a notch at the top: 2 towards the left side of the bracket and one
toward the right side of the bracket. That's only part of the problem.
You see, when holding everything so the aluminum piece that holds them
in place can be installed, one needs to figure a way to hold them in thei
r respective corners.
The aluminum retainer: it's about .060 thick, I didn't measure it. It has
the same slot spacing as the bracket but, no notch at the top. It's purp
ose is to hold the cable into the notch in the bracket. Problem is . . .
Putting the retainer in place requires that all three cables be pulled tig
ht into the notch; understandable since we really don't want any movement
in the cables. But, getting it together is a real pain in the ass. I wa
s able to get one side in, then, pulling the center cable (the throttle ca
ble) into place and getting the retainer started into that position pulls
it out of the end slot (pivots on the cable), I could get the other end
started, then it would pull out of the first end completely, then . . .
. I tried many attempts. Then, I filed the edge of the retainer slots
at the top so that it could tuck under the cable and lock in place. It
worked a little. I was able to get it started on all three. It's an ext
remely tight fit. There is really nothing to push against. The entire ca
ble support bracket moves when pushed on from the bottom. I got some chan
nel locks and tried to squeeze it together. I thought I had it when one
end came out. I broke the retainer in the middle.
Fortunately, the Project plane was there to donate it's retainer. After
carefully filing the corners of the slots, I worked that retainer into pl
ace. Two hours upside down in a Tiger.
