The D8T/D8R sits between CAT's mainstream construction dozers and the largest mining-class machines — a genuinely popular, widely-deployed production dozer used across construction, mining, and land clearing operations globally. Its pump designation (E6-3136, also referenced as SBS160 depending on the parts catalog) reflects a slightly different naming convention than the D6/D7/D9 series, worth noting when cross-referencing part numbers.

FAQs — Caterpillar D8T Pump
Does the D8T pump share a family with any CAT excavator, like the D6R and D9T do?
No — the D8T/D8R's E6-3136/SBS160 pump is genuinely dedicated to this dozer class, not shared with CAT's mainstream excavator lineup covered elsewhere on this site.
Why does my parts catalog reference "E6-3136" while another lists "SBS160" for the same machine?
Both are genuine Caterpillar naming conventions for the same pump family, used across different generations of parts catalogs. WhatsApp your machine's exact serial number and we'll confirm the correct match.
