Torque Multiplier for Crankshaft Ford EcoBoost / Opel – as 303-1611, EN-52438

This high-quality torque multiplier is essential for achieving the required final tightening torque on crankshaft central bolts and cylinder head bolts. It multiplies the applied torque by a ratio of 5:1, ensuring precise and controlled tightening according to manufacturer specifications.

Technical Specifications

• Gear ratio: 5:1 (input torque ×5)
• Drive: 1/2" square
• Output: 3/4" square
• Designed to match OEM tool specifications

Application

Ford EcoBoost 1.0L / 1.1L – Crankshaft Bolt

The holding plate is mounted at the rear of the engine in combination with the adjustable support. The multiplier is then positioned on the crankshaft.

Tightening torque:

• 60 Nm + 5 × 90°

Opel Engines (LSQ, LXD, L3T)

The multiplier is mounted onto the crankshaft holder and stabilized via the 3/4" square drive.

Tightening torque:

• 180 Nm + 90°

Ford 2.0 EcoBlue – Cylinder Head Bolts (Accessory Required)

Using a special adapter (item.no. 124771), inserted into the injector bores, cylinder head bolts can be tightened according to manufacturer specifications.

Without a multiplier, achieving required torque values is difficult and may damage tools or components.

Tightening sequence:

• Stage 1–3: 15 Nm, 25 Nm, 40 Nm
• Stage 4–5: 90°
• Stage 6: 90° (with multiplier)

Application

The torque multiplier (1) must be used in conjunction with the adapter plate (2) and the special adapter (3).

Mount the special adapter (3) onto the adapter plate (2).
Attach the tool assembly, consisting of the special adapter (3) and the adapter plate (2), to the side of the engine block.

Connect the impact socket for the central bolt to the torque multiplier (1).
Place the impact socket onto the central bolt of the pulley and secure the arm of the torque multiplier (1) to the threaded stud of the special adapter (3).

Attach a ratchet or torque wrench to the torque multiplier (1) and loosen the central nut or tighten it to the specified torque.
