I have an annoying oil leak from the starter motor drain hole on my 26 T.

A search on the forum came up with a couple of suggestion, one was installing an oil seal, the other was installing an o ring on the inside of the bushing.

This is the method I tried first, partly because I had the O ring on hand. I certainly slowed the leak down, but it is still leaking.

On the forum there are a few links to the description on how to install the oil seal, unfortunately none of the links would open?

Wondering if anyone has the procedure saved and can repost or forward to me

Push the bushing out, cut it down about 3/8", enough for the seal thickness, press it back in, oil the seal where it contacts the shaft & press in the lip seal.

When you put the seal in be sure to orient the open side (with the spring) toward where the oil would come from, that is facing the hogs head.

You are correct about the correct orientation of seals.

I may be wrong, but I put them in "backwards" for the following reasons. Its easier to install with out damaging it. T crank case is not pressurized, so I am not concerned with oil blowing by the seal. If it did a little, there would be no chance of the bushing going dry.
I have done this on my personal T starters, have not seen any drip from them.
Your thoughts?

When you check your oil does it pour out the top hole? If you fill a T engine up to full of oil it will come out the starter hole more often than just a few drips every so often.

Does anyone have the part number of the seal?
Yes, that is correct the more oil in the engine the worse the oil leak at the starter is, but I want to run with the oil reservoir topped up for a number of reasons.

Here is a visual of the correct level. Too much is not good for the engine. Jim Patrick

I recently used the seal kit from Langs referenced in this old post.

I had to ream out the new bushing for my armature shaft and straighten it to prevent binding.
I like the idea of trimming the old bushing and just using a new seal.
There was a good video at Model T Tips but that link doesn’t seem to be working now.
