5.
Measure the distance between the lobe surface and the mounting surface of the
pump cover (0030). Next remove the lobe and peel off the necessary number
of layers from the shim (0171) to adjust the distance to the setting dimension
given in the table in section 3.1. (Thickness of one layer is 0.05 mm).
6.
Reassemble the shim (0171) and rotors (0020), put the O-ring (0800) on the
retainer and tighten the retainer (on TL4 use Loctite 243) clockwise with
specified torque.
7.
Assemble and adjust the second rotor in the same way.
8.
Check the clearance between the rotors and the rotor case, see table in section
3.1 Rotor clearances.
9.
Place the pump cover (0030) on the rotor case. Be sure that the O-ring (0801)
stays in the groove and is not squeezed between pump cover and rotor case.
10.
Secure the pump cover with the cap nuts (0450).
