Checking rotor abutment alignment.
Note: Incorrect setting of rotor alignment will
damage the pump.
1. Set the position of the missing spline in
the shafts (51 and 52) to approximately
90deg to each other (e.g. 12 o’clock and 3
o’clock).
2. Fit the rotors (3) ensuring to align the
missing spline in the rotors with the
missing spline on the shafts.
3. Fit the rotor nut (4) and tighten fully
locking the rotors against each other if
required.

1. Rotate the rotors to allow measurement of
the rotor wing face to face axial alignment.
2. Using a depth micrometre ensure axial
alignment is within a tolerance of
0.015mm (0.0006 in) across each wing,
rotating the rotors as required.
3. If the alignment is within tolerance move
to step 15. If the alignment is incorrect,
note the adjustment required and move to
step 19 to adjust the abutment shims (37).
Note: If used rotors are being refitted it may
be difficult to accurately measure face to face
axial alignment due to rotor wear. In this case
the rear rotor hub to rotor front wing
clearance should be checked using a feeler
gauge. 3206-0036
