FAQ
Does this seal include the wear sleeve?
No. The Cummins 4931561 seal is the seal only. Some applications may require a wear sleeve depending on crank condition.
Should this seal be installed dry or lubricated?
Cummins requires the installation tool and specific lubrication procedure. Do not over-lubricate the sealing surface.
What are the signs of a failing front crankshaft seal?
Oil mist around the balancer, buildup on the front cover, or visible drips while idling.
Is this seal better than aftermarket alternatives?
Yes—OEM Cummins seals are built to tighter tolerances and maintain crankcase pressure control critical to 6.7L performance.
Can this seal be used on high-performance or tuned trucks?
Yes. OEM is always recommended for high-boost or higher crankcase pressure environments.
