Parker Denison T6D-020-1L00-B4 Hydraulic Pump – 024-40951-4

Series-specific model code

Original model: T6D-020-1L00-B4

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

Evidence profile: T6D series-first T-family profile (manual-evidence revision 7)

Code segment	Evidence-bound meaning
T6D	Series code: T6D.
020	Pump core documented displacement: 66.0 cm3/rev.
1	T6D shaft code: 1. Contact us to confirm.
L	Rotation: left-hand (counter-clockwise), viewed from the shaft end.
00	Porting code: 00 (standard porting).
B	Design letter: B.
4	Seal code 4: EPDM 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.
