I've been tasked with making two of these hydraulic valve blocks.
The two centre most thread bores each take a pilot operated check valve as shown below
The recess where the O-ring seals appears to be be quite a steep taper, about 1:3 from what I can measure with my limited measuring tools. The same ratio also seems to apply to an M8 plug on each side of the block.
Here is the plug
So can anyone tell me if there is tooling available to buy to replicate these recesses? Or are they likely to be custom ground?
These valve blocks are from some ancient mini diggers track motors and they are supposed to act as the brake for the motors. It's so ancient it is powered by a Lister diesel.
