MG TD TF 1500 - Alternative TF 1500 Gearbox rear seal

I need to replace my gearbox rear seal and differential pinion seal. The gearbox seals I see advertised are felt. I have heard that the rubber rear seal on a MGA will fit? Any suggestions for what to use for the pinion seal, not sure what the ones Moss sells are made of. thanks

The dark gray felt rear seal from Moss works fine in my TF gearbox. The gearbox is completely dry at the flange. It's been in for about 1,500 miles.

I bought a couple of white felt rear seals from Aningdon Spares about a year and half ago. They were too big and did not seal. I believe that Martin Cook was looking to correct the problem.

Can't give advice about diff.

My Moss seal was white felt. It took some fiddling but it all got stuffed in the tailhousing. No leaks thus far

I made my own gearbox seal and it works.

Here's a workshop drawing if anybody wants to follow suit.

The original felt "seal" doesn't do much. There is a spiral machined into the flange that screws the oil back in- I cant recall if it is deep enough for the felt to run on. If there is a lot of leakage, it is likely from the speedo pinion (see archives for fix), or the oil is overfilled. Also, parking on a steep uphill could make it leak if overfilled. If just a little leak, no way I would pull the box to change it. George PS- Diff seal standard modern type seal, that is easy to do.

thanks to all. RE diagram from Declan, to be safe are there other parts i should order to have on hand when I change the seals?
