Caterpillar 247-8968 is the variable displacement axial piston pump with a splined drive shaft, a two bolt mounting flange and an electrically controlled (solenoid) regulator with its wiring lead. It is used on Caterpillar 365B, 365C and 374D excavators. 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.

Slow or weak hydraulics
A worn pump loses flow and pressure: functions slow down, especially when the oil is hot.
Noise
Whining or knocking from the pump points to worn gears or pistons, or cavitation from a blocked suction line.
Contamination
Metal in the filter or oil means the pump is wearing. Replace it before debris damages valves and motors.
Fitting tips
Flush the system, change the oil and filters, fill the pump case before starting, and run at low speed first.

Yes, it was made for the Caterpillar 365B, and 6 more listed under compatible equipment. Check the old hydraulic pump is marked 247-8968 or one of the cross references, because makers change parts between serial ranges.
On the Caterpillar 365B, 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.
On piston pumps, yes. Fill the case through the drain port with clean hydraulic oil before the first start, or the bearings run dry.
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 hydraulic pump made to replace the Caterpillar 247-8968. It is not made by the original manufacturer; the number only shows what it replaces.
