10 DISASSEMBLING THE LOADER Removing Loader Lift Arms The following describes removal of the loader lift arms from the crawler. e. Attach hoist to one of the tilt cylinders. Remove cylinder mounting pins, then carry the cylinder from the crawler. f. Repeat step 3d at the opposite tilt cylinder. g. Lower the loader to the floor. 4. Support lift cylinders, then remove rod eye pin from both cylinders. It is not necessary to remove the lift cylinders. 5. If the loader is equipped with a 4-In-l bucket, disconnect clam cylinder hoses at rear of right-hand lift arm. Figure: 6 - Loader Removal Remove the exhaust stack. Attach the hoist to the lift arms close to the rear. Support the lift arms with the hoist to take weight off the eccentric pins. Remove the eccentric pins: 1. Rest the loader on the floor with the bucket flat. With the engine off, move the control lever in all directions to relieve any trapped oil in the hydraulic lines. 2. Remove the bucket. If removing a 4-In-l bucket, close openings in disconnected lines with clean caplugs. Retract bucket cylinders. 3. Remove the tilt cylinders: a. Remove side cover from return to dig actuator on right-hand tilt cylinder and disconnect the cable. b. Mark the location of the return to dig actuator on the right-hand tilt cylinder. Remove the actuator from cylinder and set it out of the way. c. With the engine off, move the control lever to Dump and Rollback positions to relieve trapped oil. Disconnect hoses at the rear of the tilt cylinders and close openings with clean caplugs. d. Start engine and raise the loader just enough to permit removal of the mounting pins at the rear of the tilt cylinders. s. 9. a. Mark the position of the eccentric pin hex head on the loader upright so the pin can be installed in the same position. b. Remove retaining bolt and washer. c. Pry the pin from the loader. Grease may be applied through the grease fitting, if difficult to remove. Back the crawler out of the lift arms. NOTE: Do not move the loader control lever with the engine running. If the crawler is to be driven for any distance, remove the lift cylinders and install steel fittings in ends of hydraulic lines. When reinstalling hydraulic lines, torque fittings to specifications in Section Installation of Eccentric Pins Eccentric pins are used to attach the loader lift arms to the loader uprights, Figure 1. Incorrect installation of either or both pins may cause the loader to rub on the 'radiator guard S
