B OOM- S ECTION 4 D IS- A SSEMBLY
Removal of the hydraulic sub-assembly from the inside of the boom is the most difficult
operation of this dis-assembly. Refer to Section 7, “Hydraulic Sub-Assembly” for removal
instructions. Remember! It is important to tie the two hydraulics carriers together during
removal. This will keep the assembly together and make it easier to remove as a unit. Be
careful when removing the hydraulic sub-assembly from the bracket.
All other components attached to boom-section 4 are exposed and require no specific
removal instructions.
