IMPORTANT:
Oil pump fitting JD PowerTech 4045 (4.5L, 4-cyl) AND 6068 (6.8L, 6-cyl) — same pump for both engine sizes. Alt: DZ100057. Used in JD 5000/6000-series tractors, forestry, and industrial equipment (1998-2010 production). Spur gear type, 5.4" rotor, 7.0" OAL.
Do NOT confuse with RE521756 (the newer PowerTech PT/Plus variant) — these are different pumps for different engine generations despite both fitting 4045/6068 blocks. Match your engine serial number prefix to determine which generation pump you need. Failure: gradual pressure decline, valve train noise at hot idle.
⚠️ Fits both 4045 and 6068. Verify engine generation — NOT same as RE521756.
