chain case drain plug

[super1c]

I asked a retired friend who was a welder about welding a piece onto the chaincase and he was very hesitant about that as the case is a casting. If it was aluminum, no problem but he did not want to put any heat to it as he was unsure as to what would happen (probably melt or distort).

Good to know, wasn't sure on what is was or how it was made. I've had older chain case stuff welded in past with no problems but sounds like a different animal.

Plus its oil contaminated. That makes welding a nightmare.

Try and weld that case with the oil contamination and casting and it could put cracks through the hole case.
As said before it better be clean and someone better be good.

Great idea just to add to this what about using a 2 piece threaded metal grommet that sandwich the casing for strength. I've seen them with thread threw the center for a plug


kinda like these ones http://www.shur-lok.com/product_dls/Sandwich_Structure.pdf

Or getting an altogether new case cover milled with a drain plug? Use OEM cover as template, mill a new one from billet and voila....a new cover with plug. Any machinist here?

You are the first I have heard of. Props to you for having the balls to do what we all have wanted to do. Keep us updated. I think you will be fine. Maybe put a blob of silicone on it to keep it from loosening. Being so thin not sure how much size changes when it gets warm. Silicone would easily be able to be removed.

LOL, don't know about balls, more like act first then think about it. I like the silicone idea. If this works out
I will be remembered throughout history as "the man who plugged a hole"

No sir you had the courage to MAKE the hole! That was heroic.

Once made the plugging was necessary...not heroic.......LOL
