Does anyone know what sizes the freeze plugs are? I tried searching but didn't get many results. I know pineapple sells a kit but I want to try and find brass ones.

 

Is something wrong with your plugs?

 

He probably got the plates lapped and nitrated...

Oh, yeah I remember his thread now.

 

I was just taking a guess

 

Out of curiosity, why are the plugs removed for nitriding or lapping?

 

Nothing was wrong with them, I removed them when having my irons re-nitrided.
They are removed because I was told that the process can fuse them together. I also read it can cause them to leak.
I apprecieate the link, However, as stated above I want to find some brass ones therefore I would like to know the sizes. I suppose I can measure the old ones. I dont think I tossed them yet.

 

For those interested the motor uses 6 - 30mm 1 - 25mm and 1 - 20 mm. I ordered them from napa. Minimum order of 6 each. The cost was about $11 for the steel ones.
