The setpoint torque deviates from the adjustable torque when using special tool 2 405 614 .
The setpoint torque deviates from the adjustable torque when using special tool 2 405 614 .
- Convert setpoint torque into adjustable torque:
(setpoint torque x L1): L2 =adjustable torque
L1 = length from the center of the grip to the reversible ratchet head
L2 = length from the center of the grip up to the insertion of the special tool in the screw
- Replace the oil filler plug (1) and the sealing ring.
Parts: Oil filler plug, sealing ring
