scores. Inspect the pump rotors for scores and pits.
Install the pump rotors in the pump body. Position a
straightedge, across the rotor faces and pump body and
use a feeler gauge to measure the clearance between the
straightedge and rotors. Clearance limits are 0.001 to
0.003 inch (0.02 to 0.07 mm) (fig. 2C-61).
Position the inner and outer rotors so that the center
of one tooth on each rotor is aligned and measure the
clearance between the tips of the teeth. Make four meas
urements. Rotate the inner rotor approximately 1/4
turn (90°) between measurements. Rotor tip clearance
should be 0.005 to 0.010 inch (0.13 to 0.20 mm) (View A,
fig. 2C-62).
Measure the clearance between the outer surface of
the outer rotor and the pump bore. Clearance should be
0.004 to 0.008 inch (0.10 to 0.20 mm) (View B, fig. 2C-62).

Pump Bushing Replacement
(1) Place pump housing, with reaction shaft sup
port mating surface facing downward, on flat, level
surface.
(2) Remove bushing using Remover/Installer Tool
J-24055 and Driver Handle J-S092 (fig. 2C-63).
(3) Install replacement bushing on Remover/

straight into housing until edge of bushing is flush with
bore.
(5) Stake bushing in two places to retain it using
blunt punch (fig. 2C-55).
(6) Use knife, with narrow blade only, to remove
burrs or high spots at stake points.
NOTE: Do not use a file or similar tool that might
remove more metal than is necessary.
