(6) Slide outer rotor into body, press to one side
with fingers and measure clearance between rotor
and body (Fig. 115). If measurement is 0.39 mm
(0.015 inch.) or more, replace body only if outer rotor
is in specifications.
(7) Install inner rotor into body. If clearance
between inner and outer rotors (Fig. 116) is 0.20 mm
(0.008 inch.) or more, replace both rotors.
(8) Place a straightedge across the face of the body,
between bolt holes. If a feeler gauge of 0.077 mm
(0.003 in.) or more can be inserted between rotors
and the straightedge, replace pump assembly (Fig.
117) ONLY if rotors are in specs.

(9) Inspect oil pressure relief valve plunger for
scoring and free operation in its bore. Small marks
may be removed with 400-grit wet or dry sandpaper.
(10) The relief valve spring (Fig. 118) has a free
length of approximately 49.5 mm (1.95 in.) it should
test between 101–110 N (23–25 lbs.) when com-
pressed to 34 mm (1–11/32 in.). Replace spring that
fails to meet specifications.
