fix for chrip in steam smoke units

If you mean the chirp found in the early Northerns, Lionel had offered a modified cover for the smoke unit that was supposed to eliminate the chirp.

Carl's site also has a fix under the "hints & tips" section.

Mike,

Don't remember exactly where it is stored among my collection. Give the Lionel helpline a call and they should have an answer, I think it was referred to as a baffle.

I have done the repair similar to the repair Carl shows on his website. I was hesitant to start, I thought the new engines might be harder to work on. Once I pulled the shell off I gained courage, the fix was not that hard. the toughest part was getting the old baffle out of the smoke unit. I cut a new baffle from the lid of a cat food can, drilled a 3/16 hole and cemented a grommet into the hole and re-installed in the smoke unit. As long as I was now inside the engine I also did the motor mount repair Carl outlined. I put it back together, the chirp is gone and smokes much better. No it does not meow.

Carl is a great guy, S-gauge genius, and master craftsman and machinist.  His approach to anything will work.  Another method is to replace the Lionel smoke unit with a Gilbert unit.  See the attached article by David Bair published earlier in the S-Gaugian.
