Parker Denison T6ED-066-028-4R00-B1 Hydraulic Pump – D-000543-0/00RO

Series-specific model code

Original model: T6ED-066-028-4R00-B1

Code coverage: Evidence-supported meanings shown. Confirmation required for remaining configuration.

Evidence profile: T6ED series-first T-family profile (manual-evidence revision 7)

Code segment	Evidence-bound meaning
T6ED	Series code: T6ED.
066	Pump core 1 documented displacement: 213.3 cm3/rev.
028	Pump core 2 documented displacement: 90.0 cm3/rev.
4	T6ED shaft code: 4. Contact us to confirm.
R	Rotation: right-hand (clockwise), viewed from the shaft end.
00	Porting code: 00 (standard porting).
B	Design letter: B.
1	Seal code 1: BUNA N seal class.

The source first segment is retained as the series code. Pump-core positions are recovered only when the shaft/rotation/porting boundary is structurally unambiguous; a documented family-local displacement table is then applied per core. An unknown series variant or option never prevents later independent fields from remaining visible.
