I’m trying to find a replacement plug that I removed from the back end of the camshaft. When I called Napa, I got a totally different freeze plug than I expected. From an initial search, I’m only finding plugs for 2.25” that I’m thinking won’t fit my 2.5” Bore.
Can anybody point me in the right direction?

It has to be the "disc blade" shape design or it will block the oil drain hole. Where is the old one?? I always reuse them without issue. AGCO p/n is 70910011.

I destroyed the old one removing it. I didn’t know it was reusable.
Thanks for the part number. When I install it, what should I use to seal it? I have black silicone and the 3M adhesive I used for the rear seal.

How ever you use the sealer, you CANNOT plug that small drain hole at the bottom !!! I always drive the plug into place and then take a punch and peen around the O.D. deforming the block just a bit in 3 places so it cannot ever fall back out. Clean the surface and brake kleen and smear some oil resist RTV all the way around with your finger to seal the gap and let it cure.
