What engines have torque sequences available?

Torque sequences are available for DD13, DD15, DD16, Cummins ISX/X15, PACCAR MX-13, Volvo D13/MP8, 6.7 Powerstroke, L5P Duramax, and 6.7 Cummins engines.

Are torque sequences in ft-lb and Nm?

Yes. All torque values are listed in both ft-lb and Nm for each pass.

Why are multi-pass torque sequences important?

Multi-pass sequences ensure even clamping load across the gasket or joint. Skipping passes or applying full torque in one pass can cause warping, leaks, or fastener failure.
