Komatsu 6754-61-1010 is the cast iron engine water pump: the plain pulley hub on a sealed bearing, the diamond two bolt mounting flange and the cast impeller. It is used on Komatsu 6D107 engines. This aftermarket version is made to the same mounting and connections as the original, so it fits where the old one came off.
Sold as one unit. Check the number on your old part, or in the parts manual for your machine, before ordering.

Yes, it is a direct replacement for the Komatsu 6754-61-1010 with the same fitting.
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.
Most failures come from contamination, cavitation from a restricted inlet, or running low on fluid. Check the inlet and the fluid before fitting the new water pump.
No. It is an aftermarket water pump made to replace the Komatsu 6754-61-1010. It is not made by the original manufacturer; the number only shows what it replaces.
