Removing and installing housing for ATF supply unit and stator shaft — VW

🧭 Before you start

Fits: VW Passat B5 (3B), VW Phaeton (3D)

Don't miss

• After installing piston "“C”", tighten bolts on outer plate carrier "“C”" and ATF pump in 2 more stages as follows.
• Ensure that the rounded edges of the thick outer plate face towards friction plate (4), not towards retaining ring (6). This improves the contact surface for the retaining ring.
• If the set of plates for clutch "“C”" has been renewed, the clutch clearance must be re-adjusted .

🔩 Torque settings

Values can differ between engine variants — check the code stamped on your block.

ℹ️ Always cross-check the exact figure against your vehicle's factory manual before final tightening — a wrong torque can damage the engine. These values are extracted from workshop data and may not cover every variant or revision.
