Confirmation today, sadly, OHC water pumps do not share any components with, nor can they be modified to suit the OHV pump. The bearing and shaft is larger than the OHV, so no chance of interchanging either, as with the seal. The bearing and shaft are too large in diameter to machine the OHV housing to fit.
Thanks to Oz for donating an OHC pump to the cause, but sadly, if we want a ready supply of OHV pumps we'll need to source them specifically. I can produce CAD to suit, of course, maybe we can modify to fit a readily available bearing and seal?
is it possible to make an adapter plate? A thick piece of aluminium, machined to bolt to the block with C/sunk Unbrakos, then drilled to take the 'other' water pump? Of course the pump will be moved further forward doing this so an electric fan might be needed.
