The only ball bearing in an overdrive is the rear one, visible with the rear 4 bolt cover removed.Are you sure it is not the selector shaft detent ball?

Hi Wagoo,

No I am not sure about much at all to be honest! Thanks for the pointer. The ball that came out was quite small.

I think disassembly is probably a good idea anyway, despite I have already spent the dosh. I am keen to learn on things as I go. I bought some circlip pliers today, I didnt even know they existed 3 months ago!

I can beat that! I built my 6x6 LandRover back in 1978 by laboriously cutting all the metal with a hacksaw, because I didn't know metal cutting discs for angle grinders existed. I'm sure that has shortened my life expectancy by 5 years.

Here is the aforementioned ball, with reference to it's size.

And where I think the item came out... See the spring slightly protruding? Don't know how the bugger got out, but I will try to squeeze it back in

There is only one photo visible. If it isn't a detent ball it may be one of the three synchroniser balls.

Thanks Wagoo, I was trying to put the images up on my phone.

The ball has come out under of where the selector yoke(?) goes over the main gear inside.

I will try again with the image.

Sam

Here goes!

Just to the right of the yoke is where a spring emerged and popped a ball out.

Sam

Yes Sam, it's one of the 3 synchroniser balls. the output gear must have moved forward a whisker when you withdrew the input shaft.There is a floating pad that the spring sits in that you can move slighly to the right to help you pop the ball back in, or You may need to push the output gear away a few thou to slide the shift collar to the left slightly to get the ball back in, taking care that the other 2 don't pop out.
