Relief valve - Pressure test PRIMARY HYDRAULIC POWER SYSTEM - Special tools (A.10.A) 1.

Park the machine on a level surface.

2.

Lower all attachments to the floor.

3.

Stop the engine.

4.

Move the control levers in all directions to release any circuit pressure.

5.

The best way to connect the hand pump is directly to the control valve. Disconnect the tube from the port of the control valve and connect the hand pump to the port. By connecting directly to the control valve, you avoid the possibility of a bad reading because of cylinder movement.

6.

Remove all dirt and grease from the connecting point.

7.

Connect the hose of the hand pump to the connecting point, but do not tighten the connection.

8.

Make sure that the hand pump is filled with oil. The temperature of the oil must be at least 21°C (70°F).

9.

Operate the hand pump to fill the hose of the hand pump with oil. Then tighten the connections.

10.

Operate the hand pump and read the pressure gauge. Record the highest indication. Check the pressure several times to make sure that the indications are correct.

11.

Compare the indication with the specification Pump - General specification (C.20.F). If the indication is not correct, replace the circuit relief valve.

NOTE: The circuit relief valves for the loader circuit are not adjustable and must be replaced if they do not meet the specification. 12.

Repeat this test after installing a new circuit relief valve.

Relief valve - Flow test Prior operation: Relief valve - Flow test (A.10.A) . 1.

Start the engine and run the engine at 2300 r/min (rpm).

2.

Hold the bucket control lever in the ROLLBACK position and close the pressure valve on the flowmeter until the pressure gauge indicates 124 bar (1800 psi). Adjust the engine speed to keep the engine running at 2300 r/min (rpm). Read the flow gauge and record the reading as test number 7.

3.

Hold the bucket control lever in the DUMP position and adjust the pressure valve on the flowmeter until the pressure gauge indicates 124 bar (1800 psi). Adjust the engine speed to keep the engine running at 2300 r/min (rpm). Read the flow gauge and record the reading as test number 8.

NOTE: Understanding the results of the tests are outlined in the steps below. 4.

Refer to Hydraulic pump - Flow test (A.10.A) If the flow indication for a circuit was approximately the same as the flow indication at the same pressure in Test Number 1 of the Hydraulic Pump Flow Test , the circuit is good.

5.

If the flow indication for a circuit was more than 3.8 L/min (one gpm) less than the flow indication at the same pressure in Hydraulic pump - Flow test (A.10.A) Test Number 1, there is leakage in that circuit.

6.

Leakage in the tilt circuits can be caused by any of the following problems: A. Damaged or worn packing in one or both of the tilt cylinders. B. Damaged or worn spool or spool bore in the loader control valve. C. Self-leveling valve (if equipped) is sticking or has worn spools. D. Defective circuit relief valves. E. Inadequate control spool travel.

7.

If the flow indication for every circuit tested was more than 3.8 L/min (one gpm) less than the flow indication at the same pressure in test number. 1, there is leakage at a point common to the entire system. A probable cause is a damaged or worn main relief valve or seals.

HITCH AND WORKING TOOL - SINGLE ARM Lift

Control valve - Overview loader lock control valve On-Road regulations require the loader arm and bucket to be locked in a ‘traveling’ position. To prevent the operator from inadvertently lowering or raising the loader or bucket causing damage to roadway, vehicles or machine. Operator to place bucket and loader in the appropriate position. Operator then switches the loader lock to on position, locking the bucket and loader in the set position. The operator will not be able to move the bucket and loader until the loader lock switch has been turned off. The switch will illuminate when Loader Lock is on. The function is always active when hydraulics are enabled. A Mechanical Machine with Loader Lock on will trigger trouble code 4952. This is expected.

4.

Move the control levers in all directions to release any circuit pressure.

5.

The best way to connect the hand pump is directly to the control valve. Disconnect the tube from the port of the control valve and connect the hand pump to the port. By connecting directly to the control valve, you avoid the possibility of a bad reading because of cylinder movement.

6.

Remove all dirt and grease from the connecting point.

7.

Connect the hose of the hand pump to the connecting point, but do not tighten the connection.

8.

Make sure that the hand pump is filled with oil. The temperature of the oil must be at least 21°C (70°F).

9.

Operate the hand pump to fill the hose of the hand pump with oil. Then tighten the connections.

10.

Operate the hand pump and read the pressure gauge. Record the highest indication. Check the pressure several times to make sure that the indications are correct.

11.

Compare the indication with the specification Pump - General specification (C.20.F). If the indication is not correct, replace the circuit relief valve.

NOTE: The circuit relief valves for the loader circuit are not adjustable and must be replaced if they do not meet the specification. 12.

Repeat this test after installing a new circuit relief valve.

Relief valve - Flow test Prior operation: Relief valve - Flow test (A.10.A) 1.

Start the engine and run the engine at 2300 r/min (rpm).

2.

Hold the lift control lever in the LIFT position and adjust the pressure valve on the flowmeter until the pressure gauge indicates 124 bar (1800 psi). Adjust the engine speed to keep the engine running at 2300 r/min (rpm). Read the flow gauge and record the reading as test number 9.

3.

Hold the lift control lever in the LOWER position and adjust the pressure valve on the flowmeter until the pressure gauge indicates 124 bar (1800 psi). Adjust the engine speed to keep the engine running at 2300 r/min (rpm). Read the flow gauge and record the reading as test number 10.

NOTE: Understanding the results of the tests are outlined in the steps below. 4.

Refer to Hydraulic pump - Flow test (A.10.A) If the flow indication for a circuit was approximately the same as the flow indication at the same pressure in Test Number 1 of the Hydraulic Pump Flow Test , the circuit is good.

5.

If the flow indication for a circuit was more than 3.8 L/min (one gpm) less than the flow indication at the same pressure in Hydraulic pump - Flow test (A.10.A) Test Number 1, there is leakage in that circuit.

6.

Leakage in the lift circuits can be caused by any of the following problems: A. Damaged or worn packing in one or both of the lift cylinders. B. Damaged or worn spool or spool bore in the loader control valve. C. Defective circuit relief valves. D. Inadequate control spool travel.

7.

If the flow indication for every circuit tested was more than 3.8 L/min (one gpm) less than the flow indication at the same pressure in test number. 1, there is leakage at a point common to the entire system. A probable cause is a damaged or worn main relief valve or seals.

Accumulator located on the right side of machine behind side skirt. NOTE: Do not expose the accumulator to temperatures above 120°F (49°C). A charged accumulator contains nitrogen compressed to 1600 PSI (11 032 kPa). High heat will cause the safety plug to blow out of the accumulator and the escaping nitrogen will propel the accumulator at a dangerous rate of speed. M407

Charging Accumulator with Nitrogen WARNING Explosion hazard! Use only nitrogen when charging the accumulator. Do not use air or oxygen that will cause an explosion. Failure to comply could result in death or serious injury. W0975A

EXCAVATING AND LANDSCAPING - CARRYING Unarticulated tools

Tool Cutting edge - Replace 1.

Cut or grind the old cutting edge from the bucket floor and sides. Remove all old weld and foreign material from the welding area.

SH88030

2.

Straighten the bucket floor and sides if required.

3.

Thoroughly clean the area where the new cutting edge will be welded.

4.

Use dry AWS-E7018 low hydrogen electrodes or either of the following equivalent low hydrogen wire feed electrodes: Gas metal arc welding (C0² or argon C0²) AWS-E70S6 or flux cored arc welding AWSE70T1.

5.

Preheat the parts to be welded (both tack and final welds) to a minimum of 400ºF (204ºC). The preheat temperature must be throughout the entire thickness of the parts joined, and at least 51 mm ( 2 in) back from the joint. Maintain preheat throughout the entire welding operation.

NOTE: This is a hardened steel edge. If not preheated, the cutting edge may later crack during use. 6.

Tack weld the preheated parts starting at the center of the bucket and working toward the outside ends.

7.

Finish welding the preheated parts starting at the center of the front edge of the bucket floor and working toward the outside ends. Repeat this operation at the back side of the cutting edge to bucket floor.

8.

Do not remove the bucket from the welding environment until the weld and metal temperature drops to the ambient temperature. Do not force the cooling rate of the welds and material.

9.

Follow the same welding procedure for welding the side cutting edges and bottom wear plates to the bucket.

10.

Bolt On Cutting Edge Replacement: Loosen and remove the bolts from the cutting edge.

11.

Remove the cutting edge from the bucket.

12.

Install new cutting edge on the bucket. Install new bolts and tighten the bolts.

EXCAVATING AND LANDSCAPING - CARRYING Unarticulated tools

15.

The dirt tooth kit consists of six teeth that are welded to the bucket cutting edge as indicated at (1). The teeth are used to break up the material when rough digging conditions are experienced. This will make it easier to fill the bucket. The teeth are intended to be used only on dirt and foundry or low-profile buckets.

16.

Tooth Point Replacement

17.

The points of the teeth are a replaceable "pin-on" design and can be obtained from Parts.

18.

To replace the "pin-on" points, use a punch that just fits into the pin hole, (1), and drive the old retaining pin from the shank.

19.

Place the new point over the shank and insert the retaining pin into the hole, (1). With a punch that contacts both sides of the metal part of the retaining pin, drive the pin until it is centered in the shank.

SH88032

2

SH88033

3

SH88034

4

NOTE: If the punch or driver is too small and just contacts the rubber center of the retaining pin, the pin will be damaged and will not retain the point.

20.

Tooth Location and Installation

21.

The bucket should be flat on the floor when placing and welding the teeth to maintain good weld points, (1).

NOTICE: Remove the bucket from the loader while welding teeth to prevent damage to the loader electrical system. 22.

Slide the replaceable points in place but do not attach with the steel/rubber pins as the rubber may be damaged during the welding process.

Bucket Tooth Spacing

NOTE: Position the teeth at these spacings, then re-center if necessary for equal spacing.

25.

Welds are high carbon steel (tooth) to high carbon steel (bucket). Use welding rods marked 7018 or some comparable rod. Weld on both sides of the tooth from the back of the tooth towards the replaceable point at (1). Stop welding 13 mm ( 1/2 in) from the cutting edge as noted at (2). Weld along the back of the tooth at (3). A minimum 5 mm ( 3/16 in) fillet weld is required for this application.

26.

Weld in the direction shown at (1).

27.

Weld a 5 mm ( 3/16 in) fillet weld along both sides and rear of the tooth at (2), high carbon steel to high carbon steel.

To prevent personal injury: Relieve all pressure before disconnecting fluid lines or performing work on the hydraulic system. Before applying pressure, make sure all connections are tight and all components are in good condition. Never use your hand to check for suspected leaks under pressure. Use a piece of cardboard or wood for this purpose. If injured by leaking fluid, see your doctor immediately. Failure to comply could result in death or serious injury. W0178A

WARNING Burn hazard! Before performing any service on the hydraulic system, you must allow it to cool. Hydraulic fluid temperature should not exceed 40 °C (104 °F). Failure to comply could result in death or serious injury. W0241A

WARNING Avoid injury! Always do the following before lubricating, maintaining, or servicing the machine. 1. Disengage all drives. 2. Engage parking brake. 3. Lower all attachments to the ground, or raise and engage all safety locks. 4. Shut off engine. 5. Remove key from key switch. 6. Switch off battery key, if installed. 7. Wait for all machine movement to stop. Failure to comply could result in death or serious injury. W0047A

NOTE: The images in these instructions may not be the actual model being worked on. All models have the same concept. 1.

Before removing the coupler, remove any attachment from the machine.

2.
