Komatsu PC390LC parts requests often arrive during planned rebuilds, field repairs or urgent downtime. VOMEKS helps equipment owners, workshops and purchasing departments organize those requests around the exact component identity, machine details and delivery requirement instead of relying on model name alone.
A planned PC390LC repair is an opportunity to group related wear items before the machine returns to service. When one component has failed after long operating hours, technicians may also inspect mating surfaces, seals, bearings and fastening hardware so the replacement is not damaged by an unresolved surrounding fault.

The PC390LC should be diagnosed by function before parts are ordered. Slow implement movement, weak travel, irregular swing or oil contamination each leads to a different inspection path, and the resulting quotation is more accurate when the request identifies the affected circuit or mechanical group.
For the Komatsu PC390LC, Priority groups for this model: Final-drive and travel components; Undercarriage wear parts; Hydraulic cylinders and related seals; and Boom, arm and bucket linkage parts. The actual order should follow inspection results, operating hours and the reason the machine entered repair.
Hydraulic leakage under load: Inspect cylinder sealing surfaces, hose connections and valve-area leakage before assuming that a single seal is the only cause. For the Komatsu PC390LC, recording the operating condition when this symptom appears gives the parts team better context.
For the Komatsu PC390LC, Gear tooth or bearing damage: Look for metal contamination, lubrication loss and misalignment in the affected reduction assembly before installing replacement gears or bearings. Treat the finding as part of the complete repair diagnosis rather than automatically replacing the first visible worn item.
For the PC390LC, send the Komatsu part number first when it is available. Add the machine serial number for assemblies that may have production changes; photos of tags, castings, ports or removed components are especially useful when the original number cannot be read.
Clean handling matters when the PC390LC hydraulic circuit has been opened. Protect ports, renew contaminated fluids or filters as required by the repair plan, and make sure debris from the original failure is not carried into a replacement pump, valve, motor or cylinder.
For an export quotation, send your required quantities, destination country and any delivery deadline together with the PC390LC identification details. We can check suitable OEM or high-quality aftermarket supply routes according to the requested component and availability.
