Why not replace the pedals with the later style plastic pedals. They never wear out. Kenny Faeth probably has some.

Former member Tom Downey, used to do this work, I believe. He is very capable.

When I bought my airplane it was equipped with a set of new style pedals (p/n 1460320), but they're worn out. The holes are more like slots, and the pedals flop and clank on the shafts. They're worn beyond the limits of the re-bush service from McFarlane.

I also have a serviceable pair of original style (p/n 0310453) that I can install. I greatly prefer the look of the old, but functionality counts too.

Those of you who have tried both kinds -- is there a noticeable difference between the pedals? Should I spend the $225 for a pair of nice new pedals, or would I be happy with the old?

Dave, ...most boats and airplanes are named after women or are referred to as "she", because LOOKS count. Go with the originals. :wink:

I have the original in my 170 and I regularly fly another Cessna with the newer style and quite frankly I have never noticed any difference except maybe where I put my toes, slightly. I'd use the original if it were me.

Minton,
Don't know where you live, but in Central Texas I used an aircraft mechanic/welder recommended by George to repair my rudder pedals :D :D :D He did great work and now there is no excessive play. It was very simple ... used washer welded to the flange on each side of the pedal. 8O I would think any qualified welding shop could do the job, under you and your mechanics supervision of course :) Sorry but I didn't take pictures. :cry:

Don't forget about the tractors George. My Jubilee (she) is named Miss Molly cause she's hot, always ready to go :D , easy to start and finishes at the exact same time I do. But the old Ford 5000 (he) is named Uncle Fester cause there ain't nothin perty bout'im, and that damn "hydromatic" transmission sucks lightbulbs :evil:

EDIT: That would be 6000, not 5000

The pictures above show the cast aluminum pedals on the left. They wear out too. The later model plastic pedals look
like the cast aluminum ones but they never wear out.

Here's an interesting fix Cessna came up with on later models to take care of rattling rudder pedals ... before they came up with plastic pedals. Back in '63, long before anyone wore ear plugs or noise-cancelling headsets, these rudder pedal rattles were probably more noticeable than today. On the copilot's pedals only Cessna installed an "anti-rattle spring", p/n 0760682-1. Service Letter SL63-4 introduces this:

Here's a clip from fig. 72 in the '62-72 182 IPC:

If one wanted to fabricate the spring it's .540" O.D., 1.5" tall, and uses .050" piano wire. A picture of it on my rudder pedal:

Cessna also used a different style, p/n 1460505-1 on the '78-'80 C-180. It appears to also put tension on the co-pilot's brake links. In 1981 the 180/185 IPC indicates that they went back to the earlier style I pictured above.
