Starter Bendix lubrication

Last Friday, I ran my TA for the first time this year.
On leaving the dining establishment, my starter drive gear jammed in the ring gear & so I could not get the car to start.
After the 2 starter mounting bolts were loosened, the bendix spring pulled the starter drive gear back. The TA then fired right up on the first pull of the starter cable.

I clearly need to lubricate the starter bendix to avoid a repeat.
What is the Groups recommendation for lubricating a starter gear & spring ? Oil ? Lithium grease ?

Just clean the bendix and leave it dry. I was always told NOT to lubricate.

If I ever lube them, I only use a very lightweight oil. Like machine oil.

I don't recall the TA starter configuration but normally there is a small square on the back where the armature pokes out. If you just turn this a little bit with a wrench, the Bendix gear should pop back without having to take any bolts out.

Way back when I had my first car a 36 TA on finding the starter jammed I was taught "put in gear-2nd and rock backwards" by pushing. Normally out jumped the bendix.

Gents,

Mine has the square shaft poking out of the starter & I tried turning that. It is a very small square, about 1/2” across flat, but I could not get enough torque with the small wrench that I had to flick the Bendix out.
We tired the rocking in 2nd but my wife was not a lot of help there.

It only took about 4 turns on each of the starter bolts for the drive gear to spring back so I don’t think it will take much lubrication to reduce the chances of a repeat.
Any on tried graphite spray greases ?

You just want to make sure you don't put anything on there that will attract grime. If anything sticks to it, it will get worse

The usual choice is dry graphite powder. Not graphite spray and not graphited grease. The dry powder is generally available in hardware stores

edit- the powder goes on a dry and clean assembly..
