How to remove knurled plug on pressure end of Master cylinder

Posted by pack36997 On 2024/4/26 15:39:03

I want to rebuild the master cylinder on my 1936 120 without damaging the knurled edge of the plug. Years ago, I would simply use a pipe wrench when rebuilding
a master cylinder in an old car but now I want to avoid damaging the knurling. Was there a special wrench made for this and if so, where would I find one? Could
I wrap the part in copper sheet to avoid damage? Any suggestions would be appreciated.
