This is a checked good used core, not a remanufactured or factory-tested unit - the supplier explicitly states internal components are not guaranteed to be all present or assembled correctly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 30-day return-or-replace after delivery\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShipping:\u003c\/strong\u003e UPS Ground from our Tennessee warehouse, 2 business day handling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eOEM \/ interchange references\u003c\/strong\u003e (verify against your casting\/tag):\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e2202770320\u003c\/li\u003e\n\u003cli\u003eA2202770320\u003c\/li\u003e\n\u003cli\u003e78510AA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eFits\u003c\/strong\u003e (engine\/year matters — read carefully): Front (input) oil pump body with gears out of a Mercedes-Benz 722.6 five-speed automatic, casting suffix 0320 (Mercedes A 220 277 03 20). The 722.6 was fitted to Mercedes-Benz rear-drive cars and SUVs from roughly 1996 through 2014 - C-Class (W202\/W203), E-Class (W210\/W211), S-Class (W140\/W220\/W221), CLK, CLS, SL and SLK, ML (W163\/W164), GL, R-Class and G-Class - behind M112 3.2L\/3.7L V6, M113 4.3L\/5.0L\/5.5L V8, M272 3.0L\/3.5L V6, M273 4.6L\/5.5L V8, and OM647 2.7L I5, OM648 3.2L I6 and OM642 3.0L V6 CDI diesels.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eImportant:\u003c\/strong\u003e Four things to check on your own pump before you order. (1) THE CASTING SUFFIX - this is the big one. Buffalo\/BEC stocks three 722.6 pump bodies that are the same diameter, same bolt pattern and look identical in photos: cast 0120, cast 0220 (Mercedes 140 277 02 20) and cast 0320 (Mercedes 220 277 03 20). This one is 0320. Pull your pump and read the raised\/stamped number on the body - only the last four digits matter. Ordering by year and model instead of by casting is how buyers end up with the wrong one. (2) BUSHING VS BEARING - the 722.6\/722.9 pump body was built with a plain bushing in the center converter-hub bore, and later with a caged needle bearing after Mercedes had bushing spin-out problems. Look straight into the center bore: a smooth bronze\/brass sleeve is bushing style, visible caged rollers is bearing style. Match what came out of your unit.\u003c\/p\u003e\n\u003cp\u003eBefore you order: confirm your transmission code and casting\/part numbers. Not sure?
