Calculating shim(s) — VW
Calculating shim(s) on VW: 19 steps, 1 torque figure. What to remove, what to tighten and to how many Nm, what to check after.
Workshop procedure for VW — the exact step sequence and torque figures, straight from real workshop data.
🧭 Before you start
Fits: VW Passat B5 (3B)
- Special tools named: 3459
Don't miss
- Ascertain thickness of shim(s) according to table and determine part No. from parts catalogue. In this example, two shims must be installed (each 1 mm thick).
🔩 Torque settings
Values can differ between engine variants — check the code stamped on your block.
| Torque | Fastener / step |
|---|---|
| 5 Nm (3.7 lb-ft) | Bolt 3459 to flange for ATF pump |
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.
📋 Procedure
- Observe general repair instructions .
- Set smooth side of retaining ring on last inner plate.
- Place 3459 on retaining ring and turn so that the 3 clips align with the 3 holes for ATF pump.
- Bolt 3459 to flange for ATF pump with 5 Nm torque. — 5 Nm (3.7 lb-ft)
- Measure from pump flange of gearbox housing (arrow) to 3459 with depth gauge.
- Note calculated value a.
- Remove 3459.
- Remove retaining ring.
- Push piston into ATF pump to stop.
- Place new paper gasket on ATF pump.
- Place straightedge (B) on stator support (arrow) and measure with depth gauge (A) to gasket of pump flange.
- Note calculated value b.
- Determine thickness of shim(s) according to table:
- Ascertain thickness of shim(s) according to table and determine part No. from parts catalogue. In this example, two shims must be installed (each 1 mm thick).
- Place three spring caps onto compression springs.
- Insert last outer plate, 3 mm thick.
- Install correct shim(s) (a).
- Place retaining ring (b) onto shim(s). Smooth side faces shim.
- Further installation instructions are described from .

Who makes these pages, and how
TorqFix was built by a mechanic — after a 2,700 km drive with five roadside repairs that no diagnostic tool could explain.
The figures on this page come from manufacturer workshop documentation and are shown as they are. The page is assembled automatically from that data — it is not written by an AI. The AI works in the chat, where it answers for your specific car. It writes nothing here.
Variants of the same model differ. Cross-check torque against the factory manual for your engine before final tightening.
