Examination
9. Clean all parts thoroughly and remove traces of the old gasket from the surfaces. Inspect the parts for wear, cracks and other damage. Replace if necessary.
14.10a Install the inner and outer gears so that the marks are positioned as shown in the figure (1.5 l)
14.10b Measure the clearance between the outer gear and the pump body
14.10v Measure the gap between the internal gear and the spacer element.
14.10g Measure the gap between the outer gear and the spacer element.
14.10d Measure the clearance between the side planes of the gears and the plane of the pump body
14.10e For gear-type pumps driven by a timing belt, install the gears by aligning the marks
14.10zh In a rotary pump, install the rotor so that the marks are facing up
10. Install the inner and outer gear wheels of the pump and measure the clearances (14.10a, 14.10b, 14.10c, 14.10g, 14.10d, 14.10e, 14.10g). Measure the length of the pressure regulator spring. Compare the values you obtained with the data given in the Technical Specifications.
Replace parts if necessary. Install the pump cover. Tighten the bolts.
Installation
