Bell housing hole plug

[thebeebe5]

Looking at before and after pics of my installed transmission and there’s what appears to be an inspection hole at the top of the bellhousing.  But I don’t remember pulling anything out of it before it went to the hot tank....  Maybe I forgot and it dissolved...  ?  I got the right side screen out and cleaned.  Was there some other screen in that hole, or a rubber plug of sorts from the factory?

I believe it’s a metal plug, similar to an electrical box knockout plug.

  It's an aluminum screen similar to the square one on the

right side. It has little tabs that fold out to hold it in the

bell housing. It's probably still in the bottom of the hot tank.

Lol. Probably.   I guess I’ll be using a rubber plug, because it definitely went to the hot tank.

 

 

?  dammit.

This is what they look like on a P-15.

Any chance something like this is available aftermarket?  Doubting I’ll find one....

The part # for that round vent screen is Mopar # 695445

AMS has one..as probably others on Ebay or elsewhere

As I recall all std transmission bell housings W/O FD had four of these screens in them up through 1950.

Thanks for the tip.   Calle AMS just now.  They have thrm in stock, but they say the measurememnt is 1 3/16”.   The hole in my ‘37 bell is 1 11/16”.    I may see if the shop that tanked it found anything though it’s been months...   otherwise I’ll make something up.

Don’t be sorry!   I’m learning as your sending info.  Happy to have all of it!!!

If it’s made of aluminum the caustic solution in the hot tank more than likely dissolved it.

Okay today I looked thru both a 1929-39 Plymouth parts book and a 1936-42 Plymouth parts book....

It's very unclear as to exactly which plug and part # is the one needed... but here you go. see what you can do with these #'s..

P3/P4 and up....661080 upper housing plug All this info from thru 1936-42 Ply parts book

                            661081 lower   ""                "

                             

The 1929-39 Ply parts book only listed Bell housing plug #660324

Try these parts numbers on a search.

Good luck!
