Side Clearance

WARNING: This page is about a different car, the 2006 Subaru Outback. However, it is still accessible from the selected car via links, so may be relevant.

Measure the clearance between oil pump inner rotor and rear chain cover. If the clearance exceeds specification, replace the rotors as a matched set.

Side clearance:

Standard

0.020 - 0.046 mm (0.0008 - 0.0018 in)

Fig 1: Measuring Clearance Between Oil Pump Inner Rotor And Rear Chain Cover

Perform the replacement part selection as follows.

When replacing all inner rotor, outer rotor and rear chain cover with new parts
On the inner rotor, outer rotor and the rear chain cover, there are identification marks of A, B, or C in locations shown on the figure. When replacing, use those with matching identification marks.
