Installation decomposition diagram
Park excavator on level ground, lower attachment to ground
Engage parking brake and implement all safety locks
Relieve all hydraulic system pressure before disconnecting lines
Clean pump and surrounding area thoroughly to prevent contamination
Use proper containment for hydraulic fluid drainage
Disconnect battery to prevent accidental engine start

Installation Steps:
Document existing pump configuration, line connections, and adjustment settings
Tag all hydraulic lines (P, A, B, T, LS, etc.) for proper reinstallation
Use proper tools for line disconnection - never force fittings
Carefully remove drive coupling and check for wear
Clean all mounting surfaces and connection points
Prime new pump with clean hydraulic fluid before installation
Install new COGENG pump using proper torque sequence and specifications
Connect hydraulic lines using new O-rings and seals
Ensure proper drive coupling alignment
Verify all connections are secure and properly sealed

System Commissioning:
Fill system with recommended Volvo hydraulic fluid
Bleed air from system following manufacturer procedures
Start engine and operate at idle to check for leaks
Gradually increase engine speed while monitoring pump operation
Check pump case drain flow for proper operation
Adjust pump settings according to Volvo service specifications
Test all hydraulic functions through complete operational cycles
Verify proper operation of load sensing and pressure compensation systems
