Hydraulic fluid leak or burst hose: what to send before a repair
Stop the affected machine work and arrange an assessment of a hydraulic leak. A wet hose, fitting or cylinder area needs identification before a replacement hose is selected. Keep clear of pressurized fluid and unsupported attachments.
Application & limits
Commercial trucks and equipment. Match the installed engine or machine, year and serial number before testing.
What the symptom or code tells you
Cat hose guidance highlights damage, rubbing and routing as inspection concerns. A visible wet area alone does not identify the original leak point; fluid can spread across nearby components.
A hose repair request is different from a machine that drifts or has weak functions without an obvious hose leak. Explain both the fluid loss and any change in control so the mechanic can prepare for the right scope.
Information to send
Use details already available from the normal operator position or your records. Do not run a test or approach a hazard to collect them.
- Machine make, model, serial number and attachment, if already available in your records.
- Where fluid was first noticed and which function was being used.
- Existing safe photos of hose markings, connection area and routing, without touching or approaching a live leak.
- Site entrance, surface conditions and whether equipment is blocking access.
What the mechanic assesses
The mechanic confirms the source, hose/fitting specification, routing and access under the machine service procedure. Fabrication capability does not establish that every coupling is stocked. Any supply, pickup and repair location must be confirmed before a visit.
Prepare a repair request
Text the machine or vehicle, exact symptom and location. We confirm scope, safe access, parts needs, pricing and availability before a visit.
