A hydraulic subassembly is preassembled outside the vehicle into which it is later installed, using an assembly tool. The components of the subassembly are fastened in predetermined positions on the assembly tool, following which hydraulic connections are made between the components. The completed subassembly is fastened to a pickup tool and then disconnected from the assembly tool, allowing an assembly operator to lift the subassembly away from the assembly tool and carry it to the vehicle for installation. The pickup tool is also used to position and hold the subassembly within the vehicle while the subassembly is being connected to hydraulic systems on the vehicle. Following installation of the subassembly, the pickup tool is unfastened from the subassembly and removed from the vehicle. |
