Hi,Ive got water coming into my oil box and had a look look at the one way valve and it seems the balls not sealing?

Whats the best way to re seat bearing (excuse the pun) its about 1/8" diameter.

Its off my 1" Minnie.

Thanks

Brass pin punch onto the ball and a sharp tap with a hammer works for me.

Preferably use a new ball after re-seating as per RevStew.

+1 … always seems to be the preferred method.

Another way to do this is to solder a new ball onto a small shaft and apply very fine grinding past or burnishing cream and lap it as you would a car valve then replace the old ball with a new one after cleaning out

If the seat's not in too bad nick, you could also try a nitrile ball – Polly sell them. I've had a lot of good results with them.

I'm tempted to try a nitrile ball in my water pump if only because it might help with the quality of my workmanship so far…

I done the 'Tap' job and is all fine now thanks

I've used that technique on hydraulic systems running up to 720bar. Now here's a thing. I wonder if such an arrangement would be more likely to leak with more pressure, or less pressure?! Anyone care to hazard a guess?
