tion shaft support housing.
(10) Install the reaction shaft to the pump hous-
ing. Tighten the bolts to 27 N·m (20 ft. lbs.).
(11) Remove bolts and carefully separate the hous-
ings. Measure the Plastigage following the instruc-
tions supplied.
(12) Clearance between outer gear side and the
reaction shaft support should be 0.020-0.046 mm
(0.0008-0.0018 in.). Clearance between inner gear
side and the reaction shaft support should be 0.020-
