BEARING (.030" U''SIZE) 1H2831 - Caterpillar

Right Side Of Machine
(11) Relief valve for the head end of the tilt cylinder. (21) Relief valve for attachment cylinder. (22) Relief valve for attachment cylinder.4. Install tee (17) and a 28 000 kPa (4000 psi) pressure gauge (12) with the correct fittings to the 6V3081 Hose. Connect the 3S6224 Electric Hydraulic Pump to the tee.
Typical Gauge And Fittings
(12) Pressure gauge. (13) 1P2375 Coupler. (14) Coupler. (15) Adapter. (16) Nipple. (17) Tee. (18) Nipple.5. Look at the test gauge and operate the electric hydraulic pump. The gauge reading must be 19 300 300 kPa (2800 45 psi).6. If relief valve (11) needs an adjustment, loosen nut (7) and turn retainer (8) either clockwise for an increase or counterclockwise for a decrease in the pressure setting of relief valve (11).
Relief Valve For Head End Of Tilt Cylinder
(7) Nut. (8) Retainer.7. When the pressure setting is correct, tighten nut (7) to a torque of 24 2 N m (18 1 lb ft). Remove the test equipment. Install the shroud.Relief Valves For Attachment Cylinders
Use the same basic procedures to test line relief valves (21) and (22) as is given for the tilt relief valves. Use pressure taps (19) and (20). The method to read the pressure settings will change according to the optional equipment on the machine.Bucket Positioner Adjustment Procedure
Make reference to on first page of Hydraulic System Testing And Adjusting section.
Bucket Positioner Adjustment
(1) Tube assembly. (2) Magnet assembly. (3) Switch assembly (under cover). (4) Screw. (5) Bolt (two). (A) Dimension 5 1 mm (.20 .04 in).1. With the engine running, move the tilt control lever to put the bucket at the correct angle to dig. Move the tilt control lever to the HOLD position. Lower the bucket to the ground and stop the engine.2. Make sure that magnet assembly (2) has its longer length perpendicular (in a vertical position) to tube assembly (1). Tighten the set screws in the magnet assembly.3. Measure dimension (A) between magnet assembly (2) and switch assembly (3). The correct dimension is 5 1 mm (.20 .04 in).4. To change dimension (A), loosen bolts (5) then tighten screw (4) just enough to move tube assembly (1) and the switch away from magnet assembly (2). Switch assembly (3) must be vertically centered with magnet assembly (2).5. Move tube assembly (1) until the front edge of switch assembly (3) is even (flush) with the front edge of magnet assembly (2).6. Loosen screw (4) and tighten two bolts (5).7. Start and run the engine. Put the lift arm assembly parallel to the ground with the bucket in a full DUMP position. Put the tilt control lever in the TILT BACK (detent) position. The action of the bucket positioner moves the control lever from TILT BACK to HOLD position when the bucket is at the correct angle to dig. If the tilt control lever does not move to the HOLD position at all, check the kickout solenoid adjustment.8. If the bucket angle
