Hyundai Excavator Hydraulic Parts: R Series

Hyundai excavator hydraulic parts for R series machines, from 5-ton mini units to the 50-ton class. We stock main pumps, travel motors, swing motors, control valves, cylinders and seal kits, in five grades: RITO, genuine, rebuild, OEM, aftermarket.

Hyundai numbers its hydraulic assemblies with its own 31 series codes, which rarely match the pump maker's model. A K5V140DTP pump on an R305-7 is sold as 31N8-10011, and buyers who search for the Kawasaki number do not find the Hyundai one. Both refer to the same unit.

For R260, R320, R360, R380 and R520, send the serial number and the assembly number from the machine plate, and we will confirm which build applies.

Tell us either number, the Hyundai 31 code or the pump maker's model, and we will cross it. Most buyers arrive with one and need the other.
