I have seen a number of solutions to tying together the front and rear baffles
underneath the cylinders on an o_320,
One solution is to attach springs. That's good, but no one seems to have any idea
of the spring size, tension etc etc
2Second solution is to use steel tie wire with a washer at either end. But I have
difficulty picturing this - how do you stop the wire from untwisting? And
what length of wire do you start off with?? Both attempts I have had result in
the twisted wire breaking before it takes up the slack and tightens the two baffles.
3.
On another aircraft (production) I have seen a rod with both ends threaded that
takes very small all steel lock nuts.
This is the solution I want, but can't find any part numbers in my Lycoming parts
book.
Anyone have an idea where I might find them??
Thanks,
Mick

I just replaced one on my IO-360 by just making a new one. It's just a
just a steel rod with a #4 lock nut on each end and a little off-set
bend in the middle. When I go to the airport on Wednesday I'll see if I
can find the old one to take some measurements for you if you're
interested in making them yourself or can't find a part number.
BTW this is probably an airframe part not a Lycoming part so you might
check a Piper or Cessna parts book for one.

*Piper lists this part number as: 87392-002 for about $45.
Try Intermountain Air at 800-433-9617.
If they don't stock them, they'll know where to get them.

Another solution I used....
Cut the heads off from four 1 inch 4-40 screws. Peen a flat on the cut end of the
screws. Drill a hole in the flat for safety wire. Connected each end of pre-measured
length of safety wire to a screw. Insert a screw, with an adjustment
nut already on screw, into hole in each baffle. Install all metal lock nut on
end of each screw. Adjust for proper length and tighten nuts.

I used #2 threaded rod with nuts and lock washers, that is available from several
sources, I got mine from a place called Small Parts that supplies to research
outfits etc. Don't have the link handy but you should be able to googel it.
Not expensive and has worked fine for over 800 hours .
