FAQ
Will this seal kit fit both 5.9L and 6.7L Cummins engines?Yes—the M-3802820 kit covers front crank seal replacement for 5.9L (12- & 24-valve) and 6.7L Cummins B/ISB engines (1989–2018). Always confirm by ESN for model sub-variants.
What’s included in the kit?
You get one front crankshaft seal and one wear sleeve—everything needed for a proper front seal replacement.
Can I reuse the old wear sleeve?
Not recommended—the wear sleeve is precision-hardened and wear-prone. Use the new sleeve for proper sealing and longevity.

No special tools required—just ensure the sleeve is seated smoothly and the seal is pressed on squarely. Confirm torque specs per the Cummins service manual.
