For HYUNDAI R505 series excavators (including R455, R485, and R505 models spanning the -7 and -9 generations), the factory original main hydraulic pump assembly corresponds to specific part numbers.
Depending on your region, production year, and configuration, your R505 could be fitted with either a Rexroth (A8VO200) or a Kawasaki (K5V200DT) setup.
The primary official part numbers for the R505 main hydraulic pump assembly are:
31NB-16110 (Most Common / Current Standard)
31Q7-40150
31Q7-40070
R(R455 / R485 / R505-7 / R505-9).
If you are looking at the tag affixed directly to the pump housing by the original component manufacturer, you will find one of these model numbers:
Rexroth Option: A8VO200 Series (e.g., A8VO200LA1H1)
Kawasaki Option: K5V200DT Series
Because these main pumps are high-value components, it is always safest to double-check the actual pump data plate before processing an order:
Look for the 10-digit Rexroth ID (usually starts with R902... or R901...) if it is a Rexroth pump.
Provide your excavator's full VIN / Chassis Serial Number to your parts dealer so they can run it through the Hyundai HCE-EPC (Electronic Parts Catalog) to verify the exact split for your specific production year.
