Re: Think I ruined my RD-23 lower gear case housing

[David Stanton]

I’ve used a propane torch to heat the housing from the outside to expand the housing, not the brass, and it definitely has helped me on a couple of RD housings, but you have to heat a long time, as it is somewhat like trying to heat a heatsink, and propane torches aren’t all that hot. I’ve yet to scorch the paint doing this.
