Cummins n-14 front main seal replacement?

To replace the front main seal on a Cummins N-14 engine, first ensure the engine is cool and disconnect the battery. Remove any necessary components such as the harmonic balancer and timing cover to access the seal. Carefully pry out the old seal, clean the sealing surface, and install the new seal, ensuring it’s seated properly. Reassemble all components in reverse order and check for leaks after running the engine.
