brake drum adjuster cam, how it get it out?

I cannot adjust my front brake adjuster cam on my 61 pan. It is frozen solid. Any ideas of how to un freeze it? I would think heat applied would warp something. Open for any ideas, thanks

penetrating oil, wait, repeat.

low heat from a propane torch may help.

An interesting tip recently posted to the VirtualIndian List was to use candle wax with heat. Penetrating oils tend to burn off too quickly, whereas the wax will flow in and stay there. Or so it is said.

Beware that it is easy to round off the square lugs on the adjustors, so either get a square socket, or reverse a 3/8" socket extension for a wrench.

I had the same problem! I just did it 4 days ago. I assume wheel is off, remove all brake-shoes, the product that i used is called ( screwloose ) i got it at autostore! about $3.87 for the smallone 10oz. What I did was soak-it-both sides,wait half hr. repeat the prosess 2times. Then i took a small wire brush & did any threads visible! blew it dry with compressor. Repeat the soaking process 1 more time,& wait 15 20 min or so. Wipe dry surrounding area where not needed! I had the ol lady put a t-shirt in my ice-water cooler. Use a propane torch at medium heat,wrap t-shirt around surronding alum. areas. This will prevent any warping & out of roundness!!! ( keep in mind while heating the adj. you have to keep soaking the rag in icewater! a quick dunk does the job.) While i was heating i also gently rapped on it with a hammer & socket to fit so no damage was created! After 5-10min. i got it loose. After i ran the threads on a wire wheel-side of my grinder,& a tap to clean the thread on the bikedrum. Then i used the good old stuff called (never-seez ). A light coat on the threads & the problem will be not there for future drumbrake changes or alignments of shoes. GoodLuck 58FLH

The candle wax idea works great. What I try to do if at all possible is to heat one side of the part that you are working on then just touch the candle to the threaded area. The goal with this method is to draw the wax into the threads. The perifin wax will lubricate the threads and as it dries it will harden seperating the rust. This has worked for me for years even on the most stuburn of bolts. It doesn't take a lot of heat to melt the wax
