IMPORTANT:
Finished cylinder liner for the John Deere 6.531D (8.7L) naturally aspirated engine. This is the LATER version — do NOT confuse with R48350 for the earlier 6.531A in 4520/4620 tractors. Both share 120.65mm bore but differ in outer dimensions and O-ring groove positions. Wet-type — always replace O-ring seals. Inspect parent bore counterbore depth before pressing in new liners. Symptoms: coolant in oil, white smoke at operating temp, unexplained coolant loss indicate liner seal failure.

⚠️ Confirm engine version (6.531A vs 6.531D) before ordering.
