Installation Guidelines – For Workshop Professionals

Pre-Installation Checklist

• □ 

  Depressurize hydraulic system completely

• □ 

  Clean valve mounting surface and surrounding area

• □ 

  Verify new valve body matches old unit dimensionally

• □ 

  Prepare new seals (recommended to replace along with valve body)

• □ 

  Use new M5x30 class 12.9 socket head screws – torque to 8 Nm

Step-by-Step Installation

1. Disconnect battery negative terminal

2. Tag and disconnect electrical solenoid leads

3. Remove hydraulic lines connected to the valve section

4. Unbolt the old valve body from the main control bank

5. Carefully remove the old unit – inspect spool bores for debris

6. Install new LQ35V00008S101 with fresh O-rings/seals

7. Torque mounting bolts evenly in a cross-pattern to 8 Nm

8. Reconnect hydraulic lines – verify no cross-threading

9. Reconnect electrical connections (ensure IP65 seal integrity)

10. Refill hydraulic fluid if lost during replacement

11. Start machine and perform function tests at low idle – check for leaks

Post-Installation Testing

• Check all excavator functions (boom, arm, bucket, swing, travel)

• Verify 2-speed travel shifting engages correctly

• Confirm swing brake releases and engages properly

• Monitor for fault codes on the machine display panel

Maintenance Recommendations for Longest Service Life

• Hydraulic Cleanliness: Maintain ISO 4406 code 20/18/15 or better – contaminated oil is the #1 cause of solenoid valve failure

• Electrical Inspection: Check coil connectors for corrosion, moisture ingress, or loose terminals every 500 hours

• Visual Check: Inspect for external leakage around valve body seals during daily walk-arounds

• Fluid Change: Follow Kobelco recommended hydraulic oil change intervals (typically 1,000–2,000 hours depending on conditions)

• Coil Resistance Test: If solenoids are reused, measure coil resistance (nominal 24V DC) to ensure no internal shorts
