Bolt Torque Settings

This article isn't about excavator final drive removal, or even final drive disassembly. This is just a simple reminder about correct bolt torque settings when you come to re-assemble a final drive unit.

If you don't have a metric torque wrench then buy one! This prevents the expensive mistakes that arise from using charts to calculate torque specifications for bolts.

kN = Axial Load in kiloNewtons Nm = Torque Setting in Newton Metres
