44842 DRAIN PLUG 2SF,4SF,2X22E,2X30G

SKU: 3737

Genuine CAT Pumps part 44842, a nylon drain plug documented for CAT's 2SF, 4SF, and 3DX direct-drive plunger pumps. It seals the crankcase oil drain port, and CAT's own service literature flags the drain plug as a known oil-leak point — a loose plug or worn drain-plug o-ring should be tightened or replaced when oil weeping appears. The catalog name also lists 2X22E and 2X30G fitment, which no retrieved source confirmed, so verify your model against CAT's parts breakdown before ordering. Listed as SKU 3737.
