This Kubota LA240 Parts Catalog PDF covers one loader across 19 pages: factory part numbers, exploded assembly views, and reference data from the main frame rails to the hydraulic cylinders. Eight sections work down the machine: Main Frame hardware (left/right rails, mount pins), Boom, Bucket with cutting edge components, and five hydraulic sections mapping hose routing, outlet block connections, tube assemblies, and cylinder components. Boom and bucket cylinders both break down to component level (rod comp., piston, head, seal kit), each carrying its own factory reference number, so you order exactly what you need. No more guessing at part numbers or calling the dealer blind. Everything is bookmarked by section: open it on your tablet, search by part name, and place the right order the first time.

Kubota LA240 Common Problems This Manual Covers
Kubota LA240 boom cylinder leaking, can't identify the correct Seal Kit.1 part number p. 16
Open the boom cylinder component diagram on page 16. Locate Seal Kit.1 in the exploded view parts list, then cross-reference to confirm the correct part number for your serial number range. Verify you have the boom assembly, not the bucket: the boom cylinder nut (Ref. No. 060) is listed at 0.045 kgf.
Manual Section: Cylinder (Boom)[Component Parts]Loader drifts down after lifting, need the correct bucket cylinder seal kit part number p. 18
Pull up the Cylinder (Bucket)[Component Parts] diagram on page 18. Locate Seal Kit.2 in the parts list; cross-reference against the Parts Number List to confirm the part number for your serial number range. The bucket cylinder nut (Ref. No. 060) is listed at 0.058 kgf, distinct from the boom cylinder nut at 0.045 kgf.
Manual Section: Cylinder (Bucket)[Component Parts]Hydraulic hose leaking at a fitting, can't match the correct hose assembly part number p. 10
Check the Hydraulic Parts Diagram on page 10. Right-hand hydraulic hoses are listed separately: Hose 8 Rh Hydraulic (Ref. No. 080) weighs 0.17 kgf. Match your hose location to the exploded view to get the correct reference number, then verify the full part number before ordering.
Manual Section: Cylinder/Hydraulic HoseBoom pivot pins and bushings worn out, can't find the correct replacement part numbers p. 6
Locate the Boom & Attachment Parts Diagram on page 6. Pins are broken out with individual reference numbers: Pin Snap (Ref. No. 020) weighs 0.007 kgf and is listed separately from cotter pins and grease fittings. Match each component to its reference number in the exploded view, then confirm part numbers.
Manual Section: BoomBucket cutting edge worn smooth, need the correct part number before ordering replacement p. 8
Go to the Bucket: Attachments Parts diagram on page 8. Edge Cutting is Ref. No. 020, listed at 6 kgf; confirm the part number. Mounting hardware (bolts, lock nuts, grease fittings) are separate line items in the same diagram, so order each component individually to get the complete set.
Manual Section: BucketHydraulic outlet block coupler damaged or missing, can't identify the correct replacement part number p. 12
Find the Hydraulic Hose(Hyd.Outlet Block) diagram on page 12. The Coupler (Ref. No. 030) weighs 0.13 kgf; Dust Plug and Sleeve are separate items in the same parts group. Cross-reference the part number, then confirm you need the outlet block coupler rather than a hydraulic tube fitting listed separately on page 14.
