Parker Denison T6EC-057-022-1L03-B1 Hydraulic Pump – 054-35759-003Z

Series-specific model code

Original model: T6EC-057-022-1L03-B1

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

Evidence profile: T6EC series-first T-family profile (manual-evidence revision 7)

Code segment	Evidence-bound meaning
T6EC	Series code: T6EC.
057	Pump core 1 documented displacement: 183.3 cm3/rev.
022	Pump core 2 documented displacement: 70.3 cm3/rev.
1	T6EC shaft code: 1. 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.

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.
