HIGHLAND MYHT Portable Hydraulic Tester Supports On-Site Excavator Troubleshooting
When an excavator develops slow hydraulic movements or reduced working performance on a construction site, maintenance teams need reliable measurements before deciding which components require further inspection. Pressure readings alone may not reveal the full picture. Checking flow and oil temperature alongside pressure provides a stronger basis for troubleshooting and helps teams focus their investigation.
The HIGHLAND MYHT series portable hydraulic tester brings these measurements to the machine, supporting on-site assessment of hydraulic pumps, motors, valves, and related circuits. Its portable design allows service technicians to carry testing equipment to the work area and investigate hydraulic performance before deciding whether workshop inspection is necessary.

From Machine Symptoms to Measurable Evidence
Consider an excavator whose hydraulic movements become slower as the machine warms up. Rather than immediately assuming that the main pump needs replacement, a technician can measure flow, pressure, and oil temperature at an appropriate test location.
Comparing readings under defined operating conditions with the machine manufacturer’s specifications helps establish whether hydraulic output meets requirements. The results can guide further checks of the pump, control valves, or other components. Measurements support the investigation; identifying the root cause still requires an understanding of the complete circuit. This approach reflects the measurement-led troubleshooting discussed in industry maintenance guidance. Reference: Webtec maintenance guidance.
Portable Testing for Field Service Teams
For the MYHT-1-5 model, HIGHLAND lists a maximum flow rating of 500 L/min and a maximum pressure rating of 420 bar. Model selection, hoses, fittings, and the test arrangement must suit the circuit being assessed. Testing should follow the equipment manuals and be performed by qualified personnel. Reference: MYHT-1-5 specifications.
| Parameter | Specification (MYHT-1-5) |
|---|---|
| Maximum flow rating | 500 L/min |
| Maximum pressure rating | 420 bar |
| Measured parameters | Flow, pressure, and oil temperature |
| Typical use | On-site assessment of pumps, motors, and valves |
Key Applications for Maintenance Teams
- On-site assessment of hydraulic pumps, motors, valves, and related circuits.
- Comparing flow, pressure, and oil temperature against manufacturer specifications.
- Gathering evidence before deciding whether workshop inspection is necessary.
- Supporting repair decisions and post-repair performance checks.
Why On-Site Hydraulic Testing Matters
Slow or inconsistent hydraulic movement is a common symptom across aging construction equipment, and it can be caused by a range of factors—from pump wear to valve leakage or fluid condition. Because several components share responsibility for hydraulic performance, a single pressure reading rarely confirms the root cause on its own.
By measuring flow, pressure, and oil temperature together at the machine, field service teams can build a more complete picture of hydraulic health. This measurement-led approach supports faster, better-informed decisions and reduces the risk of unnecessary component replacement.
For construction equipment service companies and fleet maintenance teams, on-site hydraulic testing provides practical evidence for repair decisions and post-repair performance checks.
