METHOD FOR REMOVAL AND REFITTING OF RIGID PIPES AND WIRING
METHOD FOR REMOVAL AND REFITTING OF RIGID PIPES AND WIRING 1 - The rigid pipes of the various systems can all be removed individually , i.e. without having to remove any pipes belonging to other systems. 2 - For particularly complex removal operations, number the pipes in the order in which they are removed, label any intermediate connections and the positions of the intermediate retaining clamps. Refit the pipes in reverse order to removal. 3 - After having repositioned the pipes in their original locations, tighten the fittings by hand and locate the retaining clamps and intermediate fixings. 4 - First tighten the fittings using also a holding wrench to the torques specified in the tables in Section 00, and then tighten the pipe clamps. 5 - To enable the operator to determine the correct routes for the rigid pipes and the wiring harnesses on the tractor frame, we have provided photographs showing the original routes for the two versions of the tractor with additional oil flow obtained by gear pumps and a variable displacement pump, both of which are equipped with air trailer braking.
IMPORTANT 1 - After removing pipes, immediately plug the ends of the pipes and the open fittings on the components from which they were disconnected in order to prevent the entry of contaminants. 2 - After disconnecting electrical connectors, protect them against oil, dust and other contaminants by covering them in bags made of waterproof material and attach the bags to the wiring with insulating tape. 3 - Should any oil, coolant, moisture or water come into contact with the connectors, clean them with compressed air at low pressure (max. 2 bar) and clean the wires and contacts with isopropyl alcohol or a specific water-repellent product. 4 - Check wiring fixings carefully; these must not impinge on the connectors and must be positioned at regular intervals of about 30 cm to prevent vibration that could cause an interruption in current flow or signal loss.
