Kubota TL1150 Common Problems This Manual Covers
Loader hydraulics weak or not working
Worn control valve internals rob the loader of lift and curl power. The control valve section identifies the valve body, stay, orifice, and adapter parts to inspect or replace.
Manual Section: Control Valve p. 25Loader cylinder leaking or drifting
Worn seals let the boom drift down under load. The boom cylinder component parts section breaks down the tube, rod, head, piston, and seal kit.
Manual Section: Cylinder (Boom) [Component Parts] p. 31Self-leveling not holding the bucket
A faulty self-level valve upsets bucket angle through the lift cycle. The second control valve component-parts section lists the self-level valve, spring, load check, and adjustment cap.
Manual Section: Control Valve 2 [Component Parts] p. 23Hydraulic hose leaks or runs hot
Chafed hoses and internal restriction cause leaks and heat in the circuit. The cylinder and hydraulic hose section shows the hoses, sleeves, and pump tube to replace.
Manual Section: Cylinder/Hydraulic Hose p. 11Worn boom pins and bushings
Sloppy, noisy pivots come from worn pins and bushings at the boom. The boom section lists the pins, bushings, and link components to renew.
Manual Section: Boom p. 17Bucket cutting edge worn
A worn or damaged cutting edge reduces dig performance. The bucket section identifies the cutting edge, bolt-on blade, and pins for replacement.
Manual Section: Bucket p. 19Frequently Asked Questions
