It's likely that nothing is as good as a new case, but if these 
bearings have the steel-backed #2s then they should be fine.

You should also assemble the case halves empty and use a thin 
feeler gauge to make sure that the web halves meet solidly in the 
areas above and below the #2 bearing.

The important part is whether he got the diameter right. You just

Case savers? This is the time to do it. If you do the 8mm studs, 
remember that the torque settings are different!

Large flat gear pump should be 25mm. The 26mm pump is the std 
for the dished gear.
