Cummins 4972857 is the gear driven engine coolant pump: a cast iron body with a helical drive gear on the shaft, a mounting flange and inlet and outlet necks. It is used on Cummins M11 and QSM11 engines. This aftermarket version is made to the same mounting and connections as the original, so it fits where the old one came off.

Yes, it was made for the Cummins M11, and 2 more listed under compatible equipment. Check the old water pump is marked 4972857 or one of the cross references, because makers change parts between serial ranges.
On the Cummins M11, often 5,000 to 10,000 hours with clean fluid, much less with dirt or air in the system. It is usually changed on condition, not by hours.
Leaks from the seal or weep hole, noise or whining, overheating, or falling pressure or flow under load.
If the coolant is old or dirty, yes. Worn coolant is the usual cause of seal failure, and a new pump in old coolant fails the same way.
Clean them right back to metal and fit the new gasket or O-ring dry, unless the engine manual calls for sealant.
No. It is an aftermarket water pump made to replace the Cummins 4972857. It is not made by the original manufacturer; the number only shows what it replaces.
