Transmission seals

The most current kerfuffle. I have pressure washed the gearbox and drained the gearbox. I saw that the output shaft seal was leaking, so that is now replaced. At the FRONT end of the box, there was evidence of oil being slung out against the inside of the bell housing. SO .... I bought an input shaft seal. Then I took off the bell housing. AND, what did I find? A gasket between the gearbox and bell housing. This is a 76 Midget, and looking in the Vicki Brit catalog, depending on the serial number, there may be a seal or an o-ring. The notes at the bottom left note s/n sequences, but I do not know if that means the CAR or the gearbox. If its the gearbox, I have no clue where the S/N is. There are stickers but the numbers do not correspond to the reference info.

I have a couple of pictures that I will attach to a response to this post.

Those would be gearbox numbers; chassis numbers on the 1500's would be 6 digits. I would expect to find the serial number on the main gear case.
 
I remember a thread (on another forum) where a guy was trying to cobble together a proper seal for this type of gearbox. It involved a spitfire gearbox. Apparently, some versions of this transmission used a scroll to keep the oil in, and others used a seal.

Again, I know nothing, but remember the issue being addressed recently.

Part #8, 2-8007 is the scroll type, and from the appearance, that is what is in place.

I will look again. There is at least one sticker on it, and some raised numbers here and there.
 
I would expect it to be a stamped number, but a plate would also be a possibility. Embossed numbers are usually casting/part numbers.

Ah, the beloved British scroll seal! A little oil slinging is to be expected!
 
Hey, Nigel..
What do you want, Colin?
We have run out of ruddy input shaft seals for the gearboxes !!!
Are ya daft? Nobody will notice the difference. SO .. let's have a cuppa.

No, this is the 1500 - so no scroll seal but for the life of me I can't remember what does go there.

So maybe your transmission is from a Spitfire?

Doubtful. The car has 16,000 miles on the clock and its history is two owners and no mentions of replacement. That part is a listed piece. There was evidence of some slinging of gear oil, but not much. The clutch pack and flywheel are dry. And the part numbers of the gearbox sections are correct.

In any event "it is what it is".
