Preparation is just as important as the final torque. Before installation, the mating surfaces of the engine block and the flywheel housing must be perfectly clean and free of old gasket material or burrs. Cummins often specifies the use of a specific sealant (like Loctite 5699) rather than a traditional paper gasket. Furthermore, ensuring that the dowel pins are in good condition and properly seated is necessary to guarantee the housing is centered.
| Component | Torque (Nm) | Torque (lb-ft) | | :--- | :--- | :--- | | Starter through-bolts (M12) | | 40 lb-ft | | Starter to housing (M10) | 46 Nm | 34 lb-ft |
These bolts attach the aluminum or cast iron housing to the rear of the engine block.
