Need the exact part number for your Kubota MX5100H tractor? This 358-page Kubota MX5100H parts catalog PDF covers every assembly on the machine, from crankcase internals and injection pump components to HST servo pistons, hydraulic cylinders, and eight tire configuration options. Inside: exploded-view diagrams for engine, fuel system, cooling, electrical, clutch/transmission, rear axle, front axle, steering, hydraulics, three-point linkage, hood, and ROPS, each paired with an itemized parts list. The HST section breaks down six internal component assemblies separately; the option section covers auxiliary control valves, working light kits, draft control, and swinging drawbar assemblies with full Kubota part numbers. No more calling the dealer just to read off part numbers while your tractor sits idle. Bookmarked by system: jump straight to your assembly, identify the component on the exploded view, pull the number, and place the order.

Kubota MX5100H Common Problems This Manual Covers
Kubota MX5100H HST filter part number unclear, need correct replacement for hydrostatic transmission service p. 118
Open the Clutch/Transmission section starting on page 118. The HST Component Parts exploded view identifies the charge pump and filter assembly with individual part numbers. Cross-reference the parts list to confirm the hydraulic oil filter, listed at 2.068 Lbs on page 245, matches your serial number range before ordering.
Manual Section: Clutch/TransmissionSafety switch or relay part number needed, intermittent no-crank traced to starting circuit fault p. 87
Check the Electrical System section on page 87. The Switch/Sensor and Switch/Relay exploded views break out every safety switch, relay, and connector with individual part numbers. If you're sourcing the alternator at the same time, the parts list on page 88 covers the 45A alternator assembly and its component parts separately.
Manual Section: Electrical SystemFuel filter assembly versus element-only part numbers confusing, unsure which to order for service p. 68
Check the Fuel System exploded view on page 68. The parts list distinguishes the full fuel filter assembly (1.144 Lbs, page 76) from the filter element alone (0.154 Lbs). Order the assembly part number for a complete housing swap, or the element part number for a filter-only replacement.
Manual Section: Fuel SystemAir cleaner inner versus outer element part numbers look identical, unsure which to order p. 52
Find the air cleaner breakdown on page 52 in the Engine section. The exploded view lists the complete assembly (5.5 Lbs), outer element (1.1 Lbs), and inner element (0.66 Lbs) as separate line items with distinct part numbers. Match your component to the diagram before placing the order.
Manual Section: EngineHydraulic housing crack or leak, need correct housing and seal part numbers to source replacements p. 230
Turn to the Hydraulic System section on page 230. The exploded views cover the hydraulic pump, regulator valve, oil lines, and cylinder components with individual part numbers. Verify the hydraulic oil filter part (2.068 Lbs, page 245) and confirm the housing part number against your serial number range before ordering gaskets or castings.
Manual Section: Hydraulic SystemFan belt part number needed, unsure which V-belt fits the cooling system drive p. 78
Locate the fan and drive belt components in the Cooling Water System section on page 78. The parts diagram identifies the correct fan belt part number for your serial number configuration. The replacement V-belt weighs 0.275 Lbs (page 79); use that spec to cross-check your sourced part against the parts list before ordering.
