Kubota KX101 Common Problems This Manual Covers
Boom, arm, or bucket movement weak or jerky
Weak or jerky working movement on the KX101 usually points to wear or leakage in the hydraulic control valve or the spools that direct oil to the boom, arm, and bucket circuits. This section shows the control valve assembly and its component parts for identifying worn spools and seals.
Manual Section: 0045 Control Valve 1 p. 94Hydraulic oil overheating or performance loss
Overheating oil or a general loss of hydraulic performance often traces to low fluid, a clogged filter, or degraded oil in the tank. This section identifies the oil tank, its filter, and related parts so you can service or replace them.
Manual Section: 0044 Oil Tank p. 92Travel is slow or one track pulls harder
When the machine crawls or one track pulls, the drive (travel) motor or its internal parts are common causes. This section breaks down the drive motor component parts for inspection and replacement.
Manual Section: 0040 Drive Motor Component Parts 1 p. 84Engine starts poorly, stalls, or lacks power
Fuel restriction from a clogged filter, air in the line, or a fouled supply leaves the engine hard to start or short on power. This section shows the fuel piping so you can trace and replace the affected parts.
Manual Section: 0029 Fuel Piping p. 62Hard starting or no crank
A no-crank or slow-crank condition usually points to the battery or its connections. This section identifies the battery and related hardware for inspection and replacement.
Manual Section: 0033 Battery p. 70Weak swing or swivel action
Sluggish or weak swivel and swing movement can come from wear in the swivel motor. This section lays out the swivel motor component parts for teardown and parts identification.
Manual Section: 0042 Swivel Motor Component Parts p. 88Frequently Asked Questions
