Looking up factory part numbers for your Kubota B6000 Tractor? This 70-page parts catalog (OEM #11040) runs from the crankcase through the 3-point linkage hitch, organized by Kubota's own OEM reference numbering. It holds exploded-view assembly groups and parts lists, each entry carrying reference numbers, quantities, and serial number applicability ranges. Hydraulic parts diagrams lay out both the Oil Pressure Groups and the Control Valve assembly, so you can pin down every component. The cylinder head assembly is factory-listed at 9 kgf and the head bolt at 0.058 kgf, the exact OEM data you need to confirm a part fits before you order. Wrong part. Two-week backorder. Not this time. Every group is bookmarked and the text is keyword-searchable, so you can pull it up on your phone, read off the reference number, and call the dealer knowing it's right.

Kubota B6000 Common Problems This Manual Covers
Kubota B6000 exhaust sounds excessively loud due to a rusted out or rattling muffler cover assembly
Open the parts diagram on page 20 to spot the exact exhaust components for your unit. Find the part number for COVER MUFFLER 1 in the list on page 21. Check that the replacement cover matches the factory 0.172 kgf weight before fitting, which keeps vibration damping and fitment correct.
Manual Section: Air Cleaner and Muffler Group p. 21Engine smokes heavily under load with excessive blow-by pushing oil out of the breather tube
Trace the exploded view on page 14 to identify connecting rod and piston part numbers. Match the standard PISTON part number on page 15 to your engine code. Confirm the new piston hits the 0.354 kgf weight requirement before it goes into the cylinder block.
Manual Section: Crankshaft Group p. 15Low engine oil pressure warning light stays illuminated after the tractor warms up
Examine the lubrication system breakdown on page 10 to locate the oil pump assembly. Cross-reference the ASSY PUMP OIL part number on page 11 against your engine serial number. Verify the replacement pump weighs 1.2 kgf, which confirms the correct heavy-duty casting.
Manual Section: Cam Shaft Group p. 11Cannot locate the correct replacement housing part number for a cracked transmission case
Pull the drivetrain parts diagram on page 22 for the transmission case and clutch housing breakdown. Locate the HOUSING CLUTCH part number on page 23. Match the replacement cast iron housing to the original 14 kgf weight so it safely supports the tractor chassis.

Each section lists OEM part numbers and quantities. p. 59
Where do I find the clutch housing part number in this catalog?
