Axle driven water pump

[21C105Participant @21c105]

Is it possible to add an axle driven water pump to a completed engine that does not have one, ie so that you do not have to strip down the axle which is already set up. If it is possible, in simple terms, how would you go about it, please. Thank you.

(1) Split eccentric on axle .

(2) Crosshead drive .

(3) Return crank or Joy link drive .

(4) Tender wheel driven – not highly recommended but can be made to work – I designed and built a succesful one for Neville Evans .

(5) Best advice though is not to fit a pump at all – two injectors are perfectly adequate usually .

As suggested a split eccentric is one way, this post may explain how. Here

Thanks replies – the two injectors option sounds best. There is a bush for the handfeed supply, so can I use this for the two injectors as well, or will I have to have an additional bush in the boiler? Also a suggestion as to injector size would be appreciated – it is for the sweet pea 5 inch boiler. Thanks.
