A leaking rear main seal on a Cummins diesel is one of those problems that gets worse the longer you ignore it — and the repair requires the right tools to avoid damaging the crankshaft or the new seal. This video demonstrates the installation using Torque King's purpose-built QK6000 seal and tool kit.
