A drive assembly for a fuel pump for an internal combustion engine comprising a shoe (26, Fig.5) and roller 24 rolling over the surface of a cam. The shoe defines a cavity in which the roller sits with a clearance C1 between the roller and shoe, wherein an extended clearance forms a space is defined adjacent to the roller to one or both sides of the roller, where the space C2 (at the side) has a greater dimension that the clearance (at the top). The space may be on one or both sides of the roller. The space can cover an angular range A relative from the central axis defined by a relationship to the cam pressure angle (2ɸmax
