Part of the Kubota Parts Manuals.
Kubota's B6100E-P Parts Catalog (OEM #11043) splits your tractor into 50-plus labeled assemblies across 128 pages, from the Crankcase and Piston Crankshaft Groups through the Hydraulic System, 3-Point Linkage, and Front Axle. Exploded views and parts lists cover every group, including the Control Valve, Oil Pressure, and Oil Pressure Pipe Groups. Serial-number applicability columns and I/C interchangeability codes (New-for-Old, Old-for-New) tell you which part number fits your specific build before you place an order. Need a replacement battery? Cross-reference 66704-55430 at 9.3 kgf, one of hundreds of part numbers tied to exact serial ranges. Bookmarked by system group and keyword-searchable, the file opens on your tablet so you can tap straight to the assembly you need and order right the first time.

Kubota B6100E-P Common Problems This Manual Covers
Kubota B6100E-P starter won't crank or turns over slowly, tractor won't start p. 111
Pull the Battery Group diagram on page 111 and confirm the correct replacement. The catalog lists battery part #66704-55430 (9.3 kgf / 20.46 lb). Cross-reference the Starter Group on page 47: starter assembly part #15231-63010. Check both numbers against your serial range before ordering, since the Name Plate Group on page 39 identifies your exact variant.
Manual Section: Battery GroupCan't identify the correct fuel filter element part number for the injection system p. 118
Open the Fuel Filter Group on page 118. The replacement filter element is part #15231-43560 (0.03 kgf). For the complete filter assembly, that's part #19204-43010, listed for serial numbers 10001 and up (0.37 kgf). Verify your serial number on the Name Plate Group before ordering the assembly, since earlier production units use a different configuration.
Manual Section: Fuel Filter GroupAir cleaner element part number unknown, need to match correct filter for engine intake p. 116
Check the Air Cleaner Group on page 116. The replacement element is part #15222-11220, weighing 0.344 kgf (0.7568 lb). This section covers domestic and North American variants only; overseas units are excluded from the diagram, so confirm your build code on the Name Plate Group before placing the order.
Manual Section: Air Cleaner Group Except[Overseas]Clutch disc part number needed after wear, unsure which disk fits transmission p. 37
Reference the Clutch Group exploded view on page 37. The clutch disk assembly is part #66591-13300, listed at 0.9 kgf (1.98 lb). Cross-check the Clutch Rod Group on page 59 and Clutch Housing Group on page 96 so you catch any related linkage components that may need replacing at the same time.
Manual Section: Clutch Group3-point hitch lift weak, need to identify hydraulic control valve and linkage parts p. 120
Start with the 3-Point Linkage Group on page 120, which covers the hitch arms and attachment hardware. From there, cross-reference the Control Valve Group on page 79 for the hydraulic valve assembly parts, and Oil Pressure Group 1 and 2 on pages 81 and 83 for pump-side components. Match each part number against the Oil Pressure Pipe Group on page 77 to confirm you have the full set of fittings and lines.
Manual Section: 3-Point Linkage GroupRadiator or cooling hose part number needed, overheating after coolant loss p. 100
Locate the Radiator Group on page 100. The complete radiator assembly weighs 6 kgf; use the exploded view there to identify individual hose and fitting part numbers. If you only need the upper or lower hose, find it in that same diagram. Rule out the Fuel Tank Group on page 109 if the leak location is ambiguous, then confirm your part selection against the serial number on the Name Plate Group.
