JCB VMD70 & variants Common Problems This Manual Covers
JCB VMD70 and VMD100 vibrator not rotating at full speed or reduced performance p. 122
Inspect the vibration system relief valve. Test the vibrator system working pressure on page 122 to verify it falls between 80-120 bar. If pressure is low, check the fluid level and verify the vibration system oil capacity is correct at exactly 0.15 Litres for the VMD70 model.
Manual Section: Vibration System Fault DiagnosisMachine will not move or has poor drive performance with no travel drive p. 124
Troubleshoot the hydraulic travel system using the diagnostic procedures on page 124. Connect a gauge to measure the travel drive system forwards working pressure. Verify the reading matches the 30-40 bar specification on page 122. Replace the hydraulic filter if you find restricted fluid flow.
Manual Section: Hydraulic Travel System Fault DiagnosisEngine starts but stalls under load or outputs black smoke from exhaust p. 161
Check the engine valve clearance for the HATZ 1B40 engine. Remove the valve cover and use a feeler gauge to verify the inlet and exhaust clearances measure exactly 0.10 mm as specified on page 161. Adjust the rocker arms if the clearance measurement is out of spec.
Manual Section: Engine Fault Finding - HATZ EngineExcessive vibration noise or knocking near the drum assembly indicating bearing failure p. 92
Measure the drum bearing preload clearance. Pressurize the hydraulic circuit to the maximum circuit pressure of 60 bar shown on page 92. Select and install the appropriate shims to achieve a final preload clearance between 0.1-0.6 mm as detailed on page 93.
Manual Section: Drum Bearing Pre-load Check and AdjustFrequently Asked Questions
What are the replacement specifications for hydraulic filters?
The hydraulic fluid and filter element should be changed according to the service schedules, which indicate intervals of 250, 500, 1000, or 2000 hours. The filter assembly is designed to maintain the required cleanliness level and must be serviced as per the machine's service requirements.
What are the replacement specifications for hydraulic hoses?
If a hydraulic hose or hose fitting is damaged, it must be replaced immediately, and the machine should not be used until the replacement is complete. All replacement hoses must match the original in terms of size and standard.
How do you fix JCB VMD70 and VMD100 vibrator not rotating at full speed or reduced performance?
Inspect the vibration system relief valve. Test the vibrator system working pressure on page 122 to verify it falls between 80-120 bar. If pressure is low, check the fluid level and verify the vibration system oil capacity is correct at exactly 0.15 Litres for the VMD70 model.
How do you fix machine will not move or has poor drive performance with no travel drive?
Troubleshoot the hydraulic travel system using the diagnostic procedures on page 124. Connect a gauge to measure the travel drive system forwards working pressure. Verify the reading matches the 30-40 bar specification on page 122. Replace the hydraulic filter if you find restricted fluid flow.

Document Quality
This document is a scanned PDF, not a native digital file, but it includes an OCR layer so you can search and copy the full text. The text quality is generally readable, though it has a slightly fuzzy appearance typical of scanned documents rather than crisp digital text. Diagrams and illustrations are raster images, and while most are clear with readable labels, some schematic diagrams contain very small text that is difficult to read even when zoomed in. Pages are clean with no notable scan artifacts, stains, or skewed content, and there are several pages explicitly marked as intentionally blank filler pages.
