Side Clearances

WARNING: This page is about a different car, the 2003 Nissan Pathfinder. However, it is still accessible from the selected car via links, so may be relevant.

Measure side clearances between end of oil pump housing and cam ring, rotor, vanes and control piston. Measure in at least four places along their circumferences. Maximum measured values should be within specified positions.
Before measurement, check that friction rings, O-ring, control piston side seals and cam ring spring are removed.
Standard clearance (Cam ring, rotor, vanes and control piston):

Refer to SDS, LOW & REVERSE BRAKE .
