DIY Hyd Pump

[dadandlad]

Well managed to remove pump from truck so here goes.

Get along to your local hydraulics repair shop and ask if you can have one or two of there old pumps prefrebly small ones
Strip the pump and discard the end plates,keeping the centre section gears and the gear end plates.
Mill the main body down to whatever size you require
Make two end plates which you will need to drill and tap to the main body and you have a complete pump.
Sorry if this is not very clear but hopefully you will get a better idea from the pictures.

Were did you find those gears? They look great and look like they would putout some pressure. Ed

Hi Ed
The gears are the original pump gears and the cavity they sit in is the original
Basically all you are doing is removing the bulk of the original pump and fitting a couple of end plates.
I will see if i can lay my hands on another pump and do a step by step tutorial.
The original pump was good for 100Bar but with the motors we use in modelling i will not be able to reach that sort of pressure.

There is a gentleman who lives close by and made his own pump from 2 meccano gears sat in a close fitting housing which powers his excavotor very effectivley
