Sealing a hole in an outer crankcase

Hello,

I'm after a little advice from the assembled brains on the forum. Over the winter I am going to fit an electric waterpump to my Laverda 750S. The waterpump has already been replaced once and I don't want to do it again.

The current one is an impellor driven on a shaft. The shaft passes through the outer crankcase cover and into the waterpump housing. The shaft is retained by a circlip on the inner side of the outer crankcase. It runs on a small bearing race, about 16 or 18mm in diameter. There is also an oil seal.

I intend to remove the shaft, but need to seal the hole. I bought a spare crankcase and my first thought was to have the hole filled with weld or a small plate welded over the hole.

Having been thinking about this for a while, I'd like to keep the cranckcase original if possible so that the bike can be put back to standard if needs be. I know it's a spare crankcase, but they're hard to come by and I'd like a spare in case the bike goes down the road.

I though about retaining the existing oil seal and bearing and using some penny washers secured by a bolt. I can have a spot weld put onto the nut to stop it coming free. A cheese headed bolt would not protrude very much.

Is this a workable idea, or should I just go for the welding option and to hell with returnng the bike to standard?

As ever, all advise, piss takes etc.. welcome.
