BMW 2.0L Diesel Engine Part of the oil pump gear has a consumable solid lubricant coating (see shaded area). The coating thickness is the same as the desired backlash. Axial and radial force is applied to the oil pump during installation for tight mesh; bolts are tightened. Coating is consumed with initial running, leaving the desired backlash.
