Parker Denison T6DR-31-1R00-A20-A1 Hydraulic Pump – 054-37856-0

Series-specific model code

Original model: T6DR-31-1R00-A20-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.
31	Pump core documented displacement: 99.2 cm3/rev.
1	T6DR shaft code: 1. Contact us to confirm.
R	Rotation: right-hand (clockwise), viewed from the shaft end.
00	Porting code: 00 (standard porting).
A20	Control, connection, design or special trailing selection: A20. 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.
