Side Clearance

Side clearance is the difference between the thickness of the pump gears and the depth of the pocket in the pump housing. Side clearance can be measured by laying a flat plate (1) across the mounting face of the pump housing, and measuring the distance between the plate and the gears with a feeler gauge (2).

Acceptable side clearance:

• Inner gear: 0.064 mm (0.0025 in) max
• Outer gear: 0.069 mm (0.0027 in) max
