STEP 1
Attach a suitable strap to the boom cylinder to hold the cylinder rod to the cylinder barrel.
NOTE: Lift the cylinder carefully. The cylinder is heavy and must be balanced by slings when lifting.
STEP 2
With a sling and a hoist attached, lift the boom cylinder. Align the boom cylinder with the mounting brackets on the main frame of the machine. Support the outer end of the boom cylinder on a suitable stand.
STEP 3
Install the pin through the mounting bracket and boom cylinder by driving the pin in. Secure the pin with the cap screw. Using a feeler gauge, check that the clearance between the mounting bracket and the cylinder tube mounting eye is between 0.059 to 0.118 inch (1.5 to 3 mm). If necessary, remove the cap screw and pin and add shim(s) as necessary to obtain the correct clearance. Install the pin and cap screw. Install first nut on the cap screw and tighten until the nut makes contact with the boss on the mounting bracket. Back off the nut 1/4 turn and using two wrenches, install the second nut to secure the first nut in place.
NOTE: Once installed, the cap screw will have approximately 1/16 inch (1.6 mm) of free play.
STEP 4
Start the vacuum pump. Remove the plugs and caps from the hydraulic hoses and fittings. Connect the two hydraulic hoses to the boom cylinder fittings. Shut off the vacuum pump.
Remove the strap securing the cylinder rod to the cylinder barrel.
STEP 5
Lift the boom cylinder and align the rod end of the cylinder with the mounting hole in the boom.
STEP 6
Repeat steps 1 through 5 to place the second boom cylinder on the opposite side of the boom into position.
STEP 7
Install the pin through the cylinder, shim, boom, shim, and second boom cylinder.
STEP 8
Install the shims on both ends of the pin. Install the lock rings on both ends of the pin. Install the two cap screws through the lock rings and pins. Using a feeler gauge, check that the clearance between the mounting bracket and the cylinder rod mounting eye is between 0.059 to 0.118 inch (1.5 to 3 mm). If necessary, remove the cap screw and pin and add or remove shim(s) as necessary to obtain the correct clearance. Install the pin and cap screw. Install first nut on the cap screw and tighten until the nut makes contact with the lock ring. Back off the nut 1/4 turn and using two wrenches, install the second nut to secure the first nut in place. Remove the sling and hoist from the boom cylinder.
NOTE: Once installed, the cap screw will have approximately 1/16 inch (1.6 mm) of free play.

Removal
STEP 1
Park the machine on a level surface. Lower the attachment to the ground.
STEP 2
Turn the key switch to the OFF position to stop the engine.
STEP 3
Turn the key switch to the ON position. Make sure the left control console is down in the OPERATING position and the gate lock control lever is pushed down to the OPERATING position. Check that the CONTROLS LOCK symbol is not displayed on the systems display panel. If the CONTROLS LOCK symbol is displayed, push and release the CONTROLS OFF button on the left control panel.
STEP 4
Operate the swing and attachments control levers back and forth, left and right, ten times to release hydraulic system pressure.
STEP 5
Turn the key switch to the OFF position.
STEP 6
Open the left side access doors. Open the air tank drain valve to release air pressure.
STEP 7
At the top of the hydraulic reservoir, loosen the air relief plug to release air pressure in the hydraulic reservoir. When air pressure release starts, stop loosening the air relief plug. Air pressure can also be released by lifting the rubber cover from the breather, raising the rod in the breather and releasing the air pressure. When all air pressure is released, tighten the air relief plug and close the air tank drain valve.
WARNING: Before doing any maintenance on the hydraulic system, make sure that all hydraulic pressure has been released by operating the control levers several times and the hydraulic reservoir air pressure has been released. Failure to do so could cause serious injury.
WARNING: Pressurized hydraulic system; before you replace the hydraulic filters or service the hydraulic system, release the hydraulic reservoir air pressure. If you do not follow these instructions, you can be injured.
STEP 8
Install a DO NOT OPERATE tag on the ignition key and put the key in the key switch.
STEP 9
To prevent loss of hydraulic oil when disconnecting the hydraulic lines, connect a vacuum pump to the hydraulic reservoir. (See Section 8000.)
STEP 10
Remove the top front center access cover.
STEP 11
Place a four gallon (15 liter) container beneath the swing reduction gear oil drain plug. Remove the drain plug and drain oil from the swing reduction gear until the oil level is just below the crosshatch marks on the oil level dipstick. Install the oil drain plug.
STEP 12
To aid installation, install tags on all hydraulic hoses and fittings to be disconnected during removal.
Turn on the vacuum pump. (See Section 8000).
STEP 13
Turn on the vacuum pump. (See Section 8000).
STEP 14
Disconnect the return hydraulic hose and the two hydraulic hoses from the tee. Plug the hoses and cap the fittings.
STEP 15
Disconnect the two hydraulic hoses from the elbows installed in the reaction-less swing valve. Plug the hoses and cap the elbows.
STEP 16
Remove the eight socket head cap screws, lock washers, and the four flanges. Disconnect the two hydraulic hoses from the left side of the swing motor. Remove and discard the 0-rings.
Plug the swing motor ports and the hydraulic hoses.
Disconnect the swing brake release signal hydraulic hose from the elbow installed in the left side of the swing motor. Cap the elbow and plug the hose.
STEP 17
Turn off the vacuum pump.
STEP 18
Connect suitable lifting equipment to the swing motor.
STEP 19
To aid in assembly, put an alignment mark on the swing motor and swing reduction gear. Remove the twelve socket head cap screws securing the swing motor to the swing reduction gear.
STEP 20
Carefully raise the swing motor up and away from the swing reduction gear. Move the swing motor away from the machine and place on a clean work bench.
STEP 21
Place a cloth or other suitable protective covering over the swing reduction gear to prevent contamination of the gear lubricant.
