Parts Compatible with the Kubota KX41 Mini Excavator

The KX41 is the original generation 1.4 ton class entry in Kubota's K Series mini excavator family, produced from the early 1990s through the late 1990s before being replaced by the KX41-2 second generation. The KX41 and KX41H designations cover variants of the same physical machine: the H suffix indicates the hydraulic thumb factory option. Both share the chassis, drivetrain, D902 era 2-cylinder diesel engine, and hydraulic main pump. Customers commonly find KX41 machines still in fleet service in landscaping, rental, and small contractor applications because the simple mechanical injection engine and direct-drive hydraulic system are robust and supportable with widely available parts.

The KX41 shares many service parts with the KX61 (the 2.5 ton sibling in the same era) and with the KX91 (the 3 ton sibling), because Kubota engineered the original K Series on a shared parts platform with the small displacement D-series engines. Successor generation KX41-2 and KX41-3 machines use distinct engines, distinct cab designs, and distinct hydraulic plumbing, so KX41 service parts generally do not cross to those later models.

Common Replacement Parts for the Kubota KX41

Engine service is the largest order category for the KX41. Engine Oil Filter W21ESO1600 (and the alternate 16271-32092, 1627132090, and W21ES01600 aftermarket revisions) is the primary spin-on lube filter that fits the KX41 across the production run. In-Line Fuel Filter 1258143011 and Fuel Filter RA211-51280 cover the fuel system service. Engine Oil Filter HH150-32430 is the secondary aftermarket cross reference for the same lube position.

Internal engine service uses Gear Ring 16871-63820 (the flywheel ring gear that wears with starter engagement over decades of rental fleet use), Glow Plug 16851-65510 (the original mechanical injection cold start service), and Stud 16241-91490. Head end work uses Cylinder Head Gasket 16394-03310 and Thermostat Gasket 15676-73270. Water Pump 16251-73034 covers cooling system service as these older machines approach the end of their second or third water pump service cycle. Many of these internal engine parts cross to the KX61 and KX91 (1990s K Series siblings) and to other Kubota equipment powered by the same era D902 / D905 engine family.
