Transmission Plastic Plug
 
Hey guys, im having issues finding this part, the metal gasket that goes in between the tranny and engine on a mtx-75 has this plastic plug about the size of a silver dollar. It is right under where the starter goes. After completing my rear main I hit the area with some brake clean and the little plastic plug disintegrated.

Anyone know the part numb for this or what its actual name is?

That plate is a dissimilar metals plate so the bell housing of the transmission does not cause a reaction to the block its bolted on to. Also so they can close off the area of the bell housing with out making the motor casting larger. Believe most call it a "transmission block plate"

Any rubber grommet will fit will work. I think its usually used a peak hole to inspect items like the flywheel or flex plate with out having to remove the starter.

I went to every hardware store around here and the only thing close to what would fit is a rubber tapered plug, however, I test fit it and there is barely any clearance to clear the flywheel.

I was thinking to RTV a large 1/2 washer over the hole and JB weld the hole on the washer shut, any objections?

That's one way to do it, I suppose. I would go to the junk yard and pull one, or shave down the tapered plug you mentioned to have more clearance, or just get a price of plexy glass cut it round and rtv the edge of that. I personally would rather have plastic only around it, not sure if any could be had but what damage could happen if it came loose? Plastic will not cause the damage a metal washer would. Or if the job weld broke off and into the bell housing? Just thoughts.

Good points, I would be RTVing that washer on the outside of the housing, I suppose I could RTV the center of the washer too, so if it were to come loose im sure the flywheel would win. That way if it did come off I could replace it or if for whatever reason I needed to peek through it can be removed.

Cut a slit in it also. This is the only real "vent" that the bell housing sees.
