Caterpillar's SBS pump naming is organised by equipment weight class rather than machine type — which is why the D6R/D6N dozer and the 320D excavator, both in the 19-22/20 tonne range, converge on the same SBS120 pump family. A documented aftermarket part reference for this pump is 9T-7099, though we recommend confirming your exact number from the pump's own nameplate before ordering, since running changes exist across D6H, D6R, and D6N generations.

FAQs — Caterpillar D6R Pump
Can I use the same pump for my D6R dozer and 320D excavator?
Both share the SBS120 base pump family, but always confirm exact part numbers match before assuming interchangeability — WhatsApp both machines' nameplates and we'll confirm.
Is the D6H pump the same as the D6R/D6N?
These generations share the same broad SBS120 architecture, but confirm your exact machine and part number, since running changes exist across generations.
