TM 5-3805-260-24LINES, PLUGS AND FITTINGSHYDRAULIC LINE INSTALLATION1. For a metal tube to hose installation, install the tube and tighten all boltsfinger tight.2. Tighten the bolts at the rigid end.3. Install the hose and tighten all bolts finger tight.4. Put the hose in a position so that it does not make contact with themachine or another hose.5. Tighten the bolts on both connections.6. Start the engine.7. Move the implement control levers to all positions.8. Look at the hose during movement of the implement.Make sure hose is not in contact with the machine orother hoses.9. Shut off the engine.10. If necessary, put the hose in a new position where itwill not make contact when the implement is moved.ASSEMBLY OF FITTINGS WITHSTRAIGHT THREADS AND O-RING SEALSThis type of fitting is used in many applications.The tube end of the fitting will be different in design sothat it can be used in many different applications.However, the installation procedure of the fitting is thesame. If the tube end of the fitting body is the same asin the illustration (either an elbow or a straight body) it willbe necessary to assemble the sleeve on the tube beforeconnecting the tube to the end.ELBOW BODY ASSEMBLY1. End of fitting body (connects to tube). 2. Fittingbody. 3. Locknut. 4. Backup washer. 5. O-ringseal. 6. End of fitting that goes into other part.1. Put locknut (3), backup washer (4) and O-ring seal(5) as far back on fitting body (2) as possible. Hold thesecomponents in this position. Turn the fitting into the partit is used on, until backup washer (4) just makes contact.with the face of the part it is used on.2. To put the fitting assembly in its correct position turnthe fitting body (2) out (counterclockwise) a maximum of359. Tighten locknut (3) finger tight.NOTE: If the fitting is a connector (straight fitting) the hexon the body takes the place of the locknut. To install thistype fitting tighten the hex against the face of the part itgoes into.TORQUES FOR FLAREDAND O-RING FITTINGSThe torques shown in the chart that follows are to beused on the nut part of 37 Flared, 45 Flared andInverted Flared fittings (when used with steel tubing), O-ring plugs, O-ring fittings and swivel nuts when used inapplications to 3000 psi (20700 kPa).A29919X21-63
