This assembly of a Hydraulic Pump. Without any clearance distance, coincident mate is applied to these two flat surface of the sleeve. As a result concentric mate with body is possible only with one sleeve.

I wish to know whether there should be a clearance or not between these two sleeve flat faces.

I don’t know whether my question is clear or not.
