Parker Denison T67DBB-B20-B10-B10-3L03-B101 Hydraulic Pump – 054-34487-003

Series-specific model code

Original model: T67DBB-B20-B10-B10-3L03-B101

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

Evidence profile: T67DBB series-first T-family profile (manual-evidence revision 7)

Code segment	Evidence-bound meaning
T67DBB	Series code: T67DBB.
B20	Pump core 1 documented displacement: 66.0 cm3/rev.
B10	Pump core 2 documented displacement: 31.8 cm3/rev.
B10	Pump core 3 documented displacement: 31.8 cm3/rev.
3	T67DBB shaft code: 3. Contact us to confirm.
L	Rotation: left-hand (counter-clockwise), viewed from the shaft end.
03	Porting code: 03. Contact us to confirm.
B	Design letter: B.
1	Seal code 1: BUNA N seal class.
01	Remaining design, connection or modification selection: 01. Contact us to confirm.

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.
