Crankcase Cover Sump For Honda GX340/GX390/188F/190F Engines | Replaces OEM 11300-Z1C-600 | For 5kW-6.5kW Generators & Pumps

Need to replace a cracked or damaged crankcase cover (oil sump) on your Honda industrial engine? This is a direct replacement part designed to fit Honda GX340 and GX390 engines, as well as the similar 188F and 190F 13HP gasoline engines. It matches the OEM part number 11300-Z1C-600. These engines are commonly used to power 5kW and 6.5kW generators, water pumps, pressure washers, and other equipment. If your engine is leaking oil from the bottom or the cover is physically damaged, this is the part you need. Installation is straightforward for anyone familiar with basic engine repair – just drain the oil, remove the old cover (and any internal oil pickup tube if applicable), clean the mating surface, apply a new gasket (not always included, check your old one or buy separately), and bolt this new one on. One cover is included in the package. Always double-check your engine model number to ensure compatibility before ordering.
