This factory parts catalog covers the Kubota B5100E-P, B5100E, B5100D-P, and B5100E-PT compact diesel tractors in one downloadable PDF. It maps the whole machine by group, including the crankcase, cylinder head, injection pump, clutch, transmission shafts, differential, hydraulic control valve, steering, brakes, and the front axle groups that differ between the two wheel drive and four wheel drive variants.
Each group combines an exploded diagram with a parts table listing reference numbers, Kubota part numbers, quantities, and serial number ranges, plus interchangeability notes, so you can pinpoint the correct part for your specific variant and serial number.
Use it to order the right transmission input shaft seal, bearings, filters, or engine parts, and to tell the E, E-P, D-P, and E-PT components apart when a repair or full service comes due on your B5100.
