Parker Denison T6ECM-85-B12-1R01-C1 Hydraulic Pump – 054-46698-001

Series-specific model code

Original model: T6ECM-85-B12-1R01-C1

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

Evidence profile: T6ECM series-first T-family profile (manual-evidence revision 7)

Code segment	Evidence-bound meaning
T6ECM	Series code: T6ECM.
85	Pump core 1 documented displacement: 268.7 cm3/rev.
B12	Pump core 2 documented displacement: 37.1 cm3/rev.
1	T6ECM shaft code: 1. Contact us to confirm.
R	Rotation: right-hand (clockwise), viewed from the shaft end.
01	Porting code: 01. Contact us to confirm.
C	Design letter: C.
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.
