TR4/4A O-ring size on a A-type angle drive speedometer gear

[tdskip]

Hi guys-anyone know what the correct sizes for the o-ring oil seal by chance forward a type overdrive speedometer gear fitting?

Thanks!

The o-ring that fits between the drive and trans. case is #116. This is not the seal that goes in the drive.

Ah, so you are saying that I need part #32 which is a proper seal and not an o-ring?

 

[titanic]

Correct. #31 is an o-ring,#32 is a seal. I don't know if is a common size and available locally from an industrial supplier.

Thanks Berry.

Anyone know what size that #31 o-ring is?

 

[titanic]

The o-ring is #116,as mentioned in my first post.

Ah, sorry Berry. I thought that was a part #, not an o-ring size.

Thanks.

Most any auto parts store (e.g. my neighborhood O'Reillys) has a box of automotive O-rings (behind the counter) labeled by the three digit reference number.

Here is a chart that is handy for converting o ring size to number- https://www.marcorubber.com/sizingchart.htm
