This page focuses on 7834-77-3002 as the main part number. 7834773002 is the no-hyphen search format. Final fitment should be confirmed by the old monitor number, front panel layout, rear connector type, plug position, mounting points, engine model and machine information before ordering.

Machine and Engine Reference

Common references for this monitor display panel include Komatsu PC120-6, PC130-6 and PC200-6 excavators with 6D102 engine application. These model references should stay in the page title area, top parameters, first paragraph and image ALT text.

Machine model alone is not enough for final confirmation. Komatsu monitor panels may vary by machine version, wiring harness, connector layout, software version and cab configuration. The old monitor label and rear connector photos are more reliable than the model name alone.

For accurate ordering, compare the removed monitor with the replacement unit before shipment. Photos of the front screen, rear label, connector side, mounting area, engine nameplate and machine nameplate are useful for confirmation.

How to Confirm the Correct Komatsu Gauge Cluster

Excavator gauge clusters can look similar from the front, but small differences in rear connector, plug quantity, display layout, warning icons and mounting position may affect installation. Before ordering, compare the removed monitor carefully.

• Confirm whether the old monitor number is 7834-77-3002 or 7834773002.

• Check whether the engine application is Komatsu 6D102.

• Check whether the machine reference is Komatsu PC120-6, PC130-6 or PC200-6.

• Compare the front panel layout, display area and button arrangement.

• Check the rear connector type, plug quantity and pin layout.

• Send photos of the old monitor front side, rear label, connector side, engine nameplate and machine nameplate before quotation if you are not sure.

Common Gauge Cluster Failure Symptoms

A gauge cluster monitor may need replacement when the screen is black, dim, flickering, cracked, unreadable, shows missing display areas, cannot show warning information, has button failure or does not respond normally after power-on.

Before replacing the monitor, check the power supply, fuse, ground wire, connector, harness condition and controller communication. Some display faults may be caused by wiring or power issues rather than the monitor itself.

If the old gauge cluster was damaged by water, corrosion, unstable voltage or short circuit, the root cause should be corrected before installing the replacement monitor. Otherwise, the new display panel may fail again.

Installation and Testing Notes

Before installation, turn off the machine power and inspect the old connector. Do not force the plug into the new monitor if the connector shape, pin layout or mounting position is different.

After installation, power on the machine and check whether the gauge cluster starts normally, displays machine information, responds to buttons and shows warning indicators correctly.

If the monitor powers on but does not show correct machine data, check the wiring harness, controller communication and machine version before assuming the monitor is defective.
