Source: smartcarofamerica.com Topic: clutch actuator adjustment and torque specification conversion Models discussed: 450 Solution status: unclear

Problem: User needs to understand how to convert Newton (N) force measurements to pounds for adjusting Smart Fortwo 450 clutch actuator. Instructions specify 50 N pretension and 11 N back-off but user lacks proper torque wrench and wants to use fishing scales.

Solution: Multiple replies confirm that direct conversion from Newtons to pounds weight is not possible without torque wrenches. Conversions provided: 50 Nm = 36.88 ft-lbs, 11 Nm = 8.117 ft-lbs, 10 Nm = 7.38 ft-lbs. Users emphasize that mechanical or electronic torque wrenches are the only proper tool for accurate specification compliance. Alternative method mentioned: press shift actuator until shaft contacts transmission, then advance three graduation marks on elongated bolt holes. OP directed to Evilution.co.uk subscription resource for detailed 450 actuator adjustment procedure.

Key facts: - 50 Nm = 36.88 ft-lbs; 11 Nm = 8.117 ft-lbs; 10 Nm = 7.38 ft-lbs - Newtons (force) = mass × acceleration; cannot be directly converted from weight without both parameters - Proper adjustment requires mechanical or electronic torque wrenches; no substitute tools provide accurate results - Alternative manual method: press actuator until shaft seats in transmission, then advance three graduation marks on elongated bolt holes - Evilution.co.uk offers subscription-based detailed procedure for 450 clutch actuator adjustment
