description

Part number:SSY007305329
Part name:Main Valve A Wiring Harness
Unit name:Main valve harness project
Fit for Sany excavator SY1350C1C3KH, suitable for large‑scale mine excavation, earth‑rock stripping and heavy‑duty quarrying. Used to replace original main valve a wiring harness with damaged sheath and internal wire breakage.

Worn and aged sheath, broken inner wires, corroded and retreated connector pins will cause jerky movement, delayed response and operation failure, trigger fault codes. Partial hydraulic action loss may occur in serious cases and interrupt excavation work.

*Due to the wide variety of products, the pictures displayed may not match the actual ones, and the part numbers are mainly used.

advantages

Total harness length and connector pin definition fully match original machine for plug‑and‑play installation without rewiring.
Oil‑resistant and bend‑resistant outer sheath resists mud‑water erosion, adapts to high‑temperature hydraulic pipes and flying gravel around main valve.
Routing curve follows machine structure with proper slack to reduce wire breakage risk caused by vibration pulling.
Hydraulic‑electric fitting for large mining excavator, convenient for bulk stocking and easy on‑site replacement, meet spare‑parts stocking demand for overseas projects in Southeast Asia and Africa.

maintenance & replacement

Disconnect battery negative pole before disassembly to avoid solenoid valve and controller burnout due to short‑circuit.
Photograph wiring route before removal, hold connector body during unplugging. Never pull cable forcibly to prevent inner copper core fracture.
Route harness away from high‑temperature oil pipes and sharp edges, fix firmly with clips to avoid direct friction with metal parts.
Fully insert connectors and lock buckles. After installation, start machine, test all hydraulic movements and clear historical fault codes.
Do not reuse harness with multiple sheath damage, broken inner wires and heavily corroded connectors after insulating‑tape repair, replace main valve a wiring harness directly.
