Classic cars forum & vehicle restoration.

Bit of an off the wall question, and I'm not really expecting an answer, but if you can, I'd be grateful.

I have two of these, one an original fitment on the car, meaning that it's a congealed block of rust; and one which has been "serviced" before, as it has the screw clamp band around the vacuum housing rather than the clamp band.

Taking the path of least resistance, I stripped the one with the clamp band, removed the pistons and noted that the ball bearing in the anti-knock piston was absent.

On to unit two - an immense, titanic struggle ensued to remove the pistons (I've had to buy a new can of Plusgas). When the anti-knock piston came free, the ball bearing shot over my shoulder, hit the wall on the far side of the garage and will (obviously) never be seen again..........

So - does anyone know how big that ball bearing is? It ain't going to work properly without it and the highly detailed Girling technical data decribes it as "ball bearing".

Got a lovely little transmission place local to me who will probably provide a new ball (albeit with much tutting) if we can work out the size..

Thanks,

P45.

I'm guessing, but wouldn't it be the same diameter as the 'propulsion' spring?

Ditto to kevin2306 comment!

Had a brief chat with those nice chaps at Powertrack, who couldn't really advise me, although they were very interested in selling me the recon kit.

I trundled down to Atlantic Bearings with my anti-knock piston and a bit of measuring and logic ensued. Problem solved for pennies.

Cheers,
