Code segment	Evidence-bound meaning
T7DDS	Series: T7DDS.
B42	Shaft-end pump core (D family) documented displacement: 137.5 cm3/rev.
B35	Cover-end pump core (D family) documented displacement: 113.4 cm3/rev.
1	Shaft code 1: keyed SAE C shaft.
L	Rotation: left-hand (counter-clockwise), viewed from the shaft end.
00	Porting code: 00 (standard porting).
A	Design letter: A.
1	Seal code 1: S1 BUNA N seal class.
0Y	Unresolved value after the documented design/seal fields: 0Y. Contact us to confirm.
P31B	Special or legacy trailing code: P31B. Contact us to confirm.

The exact longest series prefix determines the number and family of pump-core slots. Displacement codes are decoded only through the family table printed for that slot; identical codes are not generalized across A-AS, A-ASW, B, C, D or E cores. Shaft identity remains tied to the complete series. R/L is interpreted from the shaft-end view. Porting 00 is standard; other catalog-shaped porting codes are retained and require physical-orientation confirmation. Unsupported families and unknown special tails fail closed without blocking earlier evidence-supported fields.
