5.5 Shimming
The pump must be shimmed for the required discharge
pressure with the following procedure (
g
Appendix A).
1. Please note that the Dura 65 can be shimmed without
draining the lubricant. Nevertheless, for changing the
lubricant from the pump housing, please refer to (→
7.4
Drain/Change the Lubricant).
2. Rotate the pump so that a rotor shoe is visible through the
inspection window.
3. Remove the inspection window and gasket. Leave the
bolts on the inspection window for reassembly.
4. Loosen the shoe bolt.
5. Remove any existing shims.
6. Replace with correct number of shims for the required
pressure
(
g
Appendix A).
7. Tighten the shoe bolt (
g
Appendix A).
8. Repeat with the other rotor shoe.
9. Ensure the lubricant level is correct. (→ 5.9 Filling the
Pump with Lubricant).
10. Replace the window and gasket ensuring it is fitted the
correct way with the bolts (
g
5.6 Fitting the Inspection
Window).

5.6 Fitting the Inspection Window
1. Fit M8 cap head bolts with washers into the window.
The window is threaded to make bolts captive and
counter-bored on the back face.
2.
Mount the gasket on to the bolts.
3. Mount the window unit, with the bolts and gasket, over
the front cover, aligned as shown in Figure 7.
4.
Nip the bolts down in sequence. Ensure that the bolts
are not over-tightened. (
g
Appendix A).
You can see the gasket pressing against the window
as the bolts clamping force takes effect.
5.7 Installing the Hose
Connect the motor to the power supply and run the pump
slowly to ensure correct connection.
1. Lubricate the hose generously with Verderlube/Verdersil.
2. Insert the hose into the lower port.
3. Run the pump forward and stop when the hose protrudes
about 40mm.
Ensure the hose is installed as indicated in 5.8 Flange Assem-
bly.
