IMPORTANT:
Finished liner for JD 6619T/A (10.14L) — LATE version (R77640). Do NOT confuse with R65629 (EARLY version). Both share 130.18mm bore but have different outer dimensions. Late version fits 8630/8640/8650 and 8820 combine. Wet-type — always replace O-ring seals. Reusing old seals is the #1 cause of post-rebuild coolant leaks. Inspect parent bore for cavitation pitting.

⚠️ Verify early vs late version and serial number breaks.
