Part of the Kubota Parts Manuals.
This is the factory parts catalog for the Kubota LA853 front loader, a 66 page reference organized by system with exploded diagrams matched to Kubota part numbers, quantities and serial number ranges. It covers the loader itself, from the main and side frame through the boom, bucket, quick bucket, control valve, control lever and full hydraulic circuit.Use it to identify the exact replacement part before ordering. Each section pairs a picture page carrying reference numbers with a part number page, and the optional quick hitch, pallet fork and bale spear attachments are broken out separately.For owners and independent mechanics servicing a loader that leaks, drifts or will not latch, it removes the guesswork of matching worn cylinders, hoses, valves and pins to the correct part numbers.

Kubota LA853 Common Problems This Manual Covers
Loader lifts slowly or not at all
Weak or dead lift usually traces to control valve wear, low fluid or a clogged filter. The control valve section exploded the valve so you can identify the internal parts that restrict flow.
Manual Section: Control Valve p. 26Bucket drifts down when held
A bucket that creeps down after being raised points to internal leakage past worn cylinder seals. The bucket cylinder section identifies the piston, head and seal parts for a reseal.
Manual Section: Cylinder (Bucket) [Component Parts] p. 57Hydraulic leaks at hoses and fittings
Aging hoses, sleeves and fittings weep oil around the outlet block. The hydraulic hose section lists the individual hoses, bands, sleeves and block for accurate replacement.
Manual Section: Hydraulic Hose(Hyd.Outlet Block) p. 48Bucket responds backward to joystick
A loader that reacts opposite to input often has misrouted lines or a control linkage fault after a repair. The control lever section diagrams the lever, cable and linkage parts.
Manual Section: Control Lever p. 41Quick attach will not latch securely
Broken or worn clamping and latch pins keep the quick attach from locking. The quick hitch option section breaks out the latch handle, spring, pins and links.
Manual Section: Quick Hitch [Option] p. 59Boom cylinder seal weeping
Oil weeping at the boom cylinders signals worn rod and piston seals. The boom cylinder section exploded the tube, rod, head, piston and seal kit for a rebuild.
Manual Section: Cylinder (Boom) [Component Parts] p. 55Frequently Asked Questions
