Parker Denison T6DR-28-3R02-B31-A1 Hydraulic Pump – 024-49199-0021

Series-specific model code

Original model: T6DR-28-3R02-B31-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.
28	Pump core documented displacement: 90.0 cm3/rev.
3	T6DR shaft code: 3. Contact us to confirm.
R	Rotation: right-hand (clockwise), viewed from the shaft end.
02	Porting code: 02. Contact us to confirm.
B31	Control, connection, design or special trailing selection: B31. 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.
