I am upgrading and old T1 6-18009 to ERR TMCC. All is complete except for the smoke unit. When received, the smoke unit was disconnected. Opening the smoke unit, the gasket was damaged. Managed to make a gasket, but there was no batting in the unit.
This appears to be a common design for older large engines. It looks like the air flow path is from the bottom of the chamber, and I'm not sure how to add batting so as to not restrict the air flow.
Any suggestions would be appreciated.
