EXCERPT:
24. COMPONENTS SYSTEM
24.1.2.3 OPERATION
(1) Lever in neutral position
In this case, the force of the secondary pressure setting spring (241) that determines the output pressure of the pilot valve is not transmitted to the spool (201). Accordingly, the spool (201) is pushed up by the return spring (221) and spring seat (216) permitting the output port 2, 4 to connect with the tank port T. This makes the output pressure equal to the tank pressure.
Lever in neutral position
(2) When the Lever is tilted
When the lever is tilted, the push rod (212) strokes. The spool (201) and spring seat (216) moves downward to make the port P to connect with the port 2, 4. With the result that the oil of the pilot pump flow out to the port 2, 4, to produce a pressure.
When Lever is tilted
(3) The Lever being held
When the lever is tilted till the pressure of the port 2, 4 rises to an oil pressure corresponding to the set spring force, the hydraulic pressure is balanced with the spring (241) force. And when the pressure of the port 2, 4 rises above a set pressure, the port P are closed and the port T are opened. When the pressure of the port 2, 4 falls below a set pressure, the port P are caused to open and the port T are caused to close, thus holding the second pressure constant.

33. UPPER SLEWING STRUCTURE

Tools: Spanner: 17 mm
-Tightening torque : 52 to 57 N-m (38 to 42 lbf-ft)
-Put pipe through the locking pin of the shaft, and check that the shaft rotates smoothly at a torque of approximately 78 to 108 N-m (58 to 80 lbf-ft)

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.
