Question 1

Why do hydraulic pumps need periodic reconditioning?

Accepted Answer

Hydraulic pumps operate under high pressure and are exposed to fine contaminants in the oil over time. Left unchecked, this leads to:

Internal wear on gears/pistons, reducing output pressure
Seal degradation causing internal leakage
Reduced cycle speed on attached cylinders

We recondition every pump with new seals, bearings, and a full bench pressure test before listing it.

Question 2

What maintenance intervals does Komatsu recommend?

Accepted Answer

For most Komatsu excavators and loaders, the standard service intervals are:

250 hrs — engine oil & filter change
500 hrs — hydraulic oil sampling
1000 hrs — full hydraulic filter replacement

Refer to your specific model's operation manual for exact figures, as they vary by series.

Question 3

Is this hydraulic pump compatible with PC200-8 and PC210 as well?

Accepted Answer

Yes — this pump assembly is directly interchangeable across the PC200-8, PC200-8M0, and PC210-8 variants, since they share the same mounting flange and spline configuration. If your machine has a different suffix or year, message us the chassis/serial number and we'll confirm compatibility before dispatch.
