Kubota BT820 Common Problems This Manual Covers
Weak or slow digging force
Weak boom and dipper force usually points to the backhoe control valve, including the spool and relief components, rather than a cylinder. The Control Valve section gives the exploded view and part numbers to identify what to replace.
Manual Section: Control Valve p. 31Loose, sloppy backhoe joints
Play in the boom and swing joints comes from worn pins and bushings that need periodic replacement. The Main Frame section lists the bushings, bush and mounting pins with their part numbers.
Manual Section: Main Frame p. 3Bucket teeth and edge wear
Bucket teeth and cutting edges wear down with digging and are common replacement items. The Bucket section covers the bucket parts across its diagrams so you can match the right numbers.
Manual Section: Bucket p. 15Hydraulic hose leaks
Aging hydraulic hoses seep or burst and cause slow, weak function. The Hydraulic Hose(Intake) section identifies the intake hose and fittings for replacement.
Manual Section: Hydraulic Hose(Intake) p. 42Swing cylinder leaks or drifts
A swing cylinder that leaks or lets the backhoe drift needs seals or a rebuild. The Swing Cylinder section shows the cylinder assembly, adapters and bushes with part numbers.
Manual Section: Swing Cylinder p. 7Stabilizer will not hold
A stabilizer that will not hold the machine steady often has worn pins or a tired cylinder. The Stabilizer Arm section lists the arm pins and related parts.
Manual Section: Stabilizer Arm p. 27Frequently Asked Questions
