Parker Denison T6DR-B20-5R02-A10-A1 Hydraulic Pump – 054-34753-0020

Series-specific model code

Original model: T6DR-B20-5R02-A10-A1

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

Evidence profile: T6DR series-first T-family profile (manual-evidence revision 7)

Code segment	Evidence-bound meaning
T6DR	Series code: T6DR.
B20	Pump core documented displacement: 66.0 cm3/rev.
5	T6DR shaft code: 5. Contact us to confirm.
R	Rotation: right-hand (clockwise), viewed from the shaft end.
02	Porting code: 02. Contact us to confirm.
A	Design letter: A.
1	Seal code 1: BUNA N seal class.
0	Remaining design, connection or modification selection: 0. Contact us to confirm.
A1	Control, connection, design or special trailing selection: A1. 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.
