It is used on Kubota M95S, M105S and M108S tractors. This aftermarket version is made to the same mounting and connections as the original, so it fits where the old one came off.
It replaces Kubota 3N300-82200, Kubota 3N300-82203 and Kubota 3N300-82204.
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 is a direct replacement for the Kubota 3N300-82200 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.
Yes. Fill the pump and its suction line with clean fluid before the first start. Running it dry, even for a few seconds, can score it.
On piston pumps, yes. Fill the case through the drain port with clean hydraulic oil before the first start, or the bearings run dry.
No. It is an aftermarket hydraulic pump made to replace the Kubota 3N300-82200. It is not made by the original manufacturer; the number only shows what it replaces.
