 After finishing the bevel work, the two bearing blocks should fit easily into the pump body.

If there is any interference, simply remove the burrs with a file, or remove enough material (using sandpaper or a lathe) from the bearing block cylindrical ends to allow the blocks to slip together.

 Once we have a good fit between the blocks, it's time to drill and tap oil system holes. We'll begin with the oil jet through-holes.

First, locate and mark the (3) drilling positions as indicated. Notice that the positions are measured from the outer edge of the bearing block. (Inner cylindrical edge fits inside pump body.)

Next, using a 0.125-inch drill bit, drill hole (a) 0.5" from the edge, 0.5" deep.  

Drill hole (b) using a 0.25-inch diameter drill, 0.75" from the edge, through to the center bore.  

Drill hole (c) with a #7 bit, 1.25" from the edge, 0.75" deep, and thread with a (.25-20) tap.  All holes are centered side to side. Drill and tap both bearing blocks the same.

 The next operation involves drilling and tapping for a pipe fitting on the bottom of the pump body.

Referring to Figure 7, the inside bottom of the pump body is scarfed out to act as a volute region (to increase fluid pressure). The hole drilled for the oil fitting is located in the center of the volute cut, so this face must be up when drilling and tapping.
