Water pumps.

Just a few of the many water pumps I have collect/purchased in the last couple of weeks. With so many engine versions no wonder there are so many "B" series pumps to choose from.
I wonder what you call a collection of water pumps? A Drip, A Puddle or maybe A Squeal.
Water pumps, water pumps every where. Trawling the Internet, checking parts books and contacting fellow J owners to measure their pumps.
Which is the correct one?
The correct water pump, measured from mounting face to front of pulley mounting face should be about 94-96 mm.

Later "B" series pumps for the 1622,1789cc engines are at least 106mm, you can even get some slightly taller than this. They are taller as they have bigger bearings and seals inside to cope with the higher power. These will fit our engines but if you have tired engine and gearbox mounts or if the retaining damper on the gearbox is out of adjustment you could find during an emergency stop the whole engine and gearbox will move forward and the fan will damage your radiator.Whats going on , well I was using one of these "panel spray" aerosol in the garage to spray a couple of items when the damn thing would not shut off.
It was one of these giant cans, although old it was over half full. So in blind panic mode I ran out of the garage round to the van. I had already de-greased the engine bay before I fitted the new water pump and fan belt, just to make it cleaner while working on the engine. I had also intended to paint various parts of the chassis while the radiator was out of the way. Well this can of "Red Oxide" certainly covered everything.
Anyway the new pump is fitted and everything works. I now have to paint the engine the correct colour and the engine bay I think will be black.
