#577 Whistling Billboard and Question

The mounting is a set of rummer gromets with a hold in the center that isolates the whistle from the shell and a small nut and bolt to hold the motor unit tight against the rubber gromet.

Check with Port line hobbies or Tripple S supplies for replacement parts.

Thanks Major

One end of the motor whisltle assembly to the frame makes sense to me.

The hole in the motor whislte plate matches the hole in the frame.

This lends nicely to your screw and grommet information.

But on the other end, the hole in the motor whistle plate is much larger.

I can't understand the reason for this.

If isolation was the reason, why two very different hole sizes?

Does the larger hole need some kind of sleeve/bushing?

Thanks again

I think the 577 and 566 are close. Could only find a sheet on the 566. Hope this helps.

Bingo!!

Thanks FlyerRich.

The parts diagram solved my mysteries.

I had to improvise a little but good to go!

Thanks to all who helped.
