The customer has a major challenge in Spx stone hydraulic pump troubleshooting. Believe me because I have faced this problem very many times before. I am sure you know how difficult it is too. This is why SpX Stone Hydraulic Pump Troubleshooting Manual was designed to help you quickly, easily, and effectively diagnose as well as repair spx stone hydraulic pump troubles. First of all, this guideline about hydraulic pump troubleshooting will give an account of spxstone hydraulic pump troubleshootingsymptoms, causes (mainly three causes), and ways to solve it from different aspects.

⚠️⚠️⚠️WARNING:
*Repair work or troubleshooting must be performed by qualified personnel who are familiar with this equipment.
*Disconnect the power supply before removing the electrical cover. Electrical work should be performed by a qualified electrician.
*Check for system leaks by using a hand pump to apply pressure to the suspect area.Watch for leaking fluid and follow it back to its source. Never use your hand or other body parts to check for a possible leak.

spx stone hydraulic pump troubleshooting

One important thing is that the problems and solutions correspond to each other in this very detailed form of spx stone hydraulic pump troubleshooting, because if you read through the form below I am sure that 90% of the issues could be resolved.

Problem 1-spx stone Electric motor does not run

Cause	Solution
Unit is not plugged in.	Plug in unit.
No voltage supply.	Check line voltage
Broken lead wire or defective power cord plug.	Replace defective parts
Defective motor	Replace or repair motor

Problem 2-Spx Stone Hydraulic Pump is not delivering hydraulic fluid or delivers only enough hydraulic fluid to advance cylinder(s) partially or erratically

Cause	Solution
Hydraulic fluid level too low	Fill reservoir to 1-1/2″ below the cover plate, maximum.
Air in system	Bleed the system.
Debris is in pump or filter is plugged	Pump filter should be cleaned and, if necessary, pump should be dismantled and all parts inspected and cleaned.
Cold hydraulic fluid or hydraulic fluid is too heavy (hydraulic fluid is of a higher viscosity than necessary).	Change to lighter hydraulic fluid.
Relief valve or low pressure unloading valve out of adjustment	Readjust as needed.
Sheared drive shaft key(s)	Replace.
Motor rotating in wrong direction	Reverse rotation

Problem 3-Pump will not build full pressure

Cause	Solution
Faulty pressure gauge	Calibrate gauge
Check for external leakage	Seal any faulty pipe fittings with pipe sealant
Inspect the pump for internal leakage	Same procedure as above but for leaks around the entire inner mechanism. If there are no visible leaks the low-to-high pressure ball check may be leaking. Remove all parts. Inspect the check body for any damage to the seat areas. Clean and reseat if necessary. Inspect the ball for damages and replace if necessary, then reassemble.
Sheared key(s)	Replace
High pressure pump inlet or outlet ball checks in the pump are leaking	Reseat or replace valve head.

Problem 4-Automatic valve will not build full pressure

Cause	Solution
Unloading pressure is too low	Increase unloading pressure per chart, sheet 3 of 4
Defective or oversize seat on automatic valve	Replace ball and seat.

Problem 5-Electric motor cuts out

Cause	Solution
Extension cord is too long and/or not of sufficient gauge.	Replace
Faulty motor	Replace and repair
Overheated motor can trip circuit breaker in shop power panel	Allow motor to cool, reset circuit breaker located in shop power panel.

Problem 6-Foaming hydraulic fluid

Cause	Solution
Hydraulic fluid being splashed by counter weight.	Lower hydraulic fluid level to approximately 38 mm (1.5 inches) below the cover plate.

Problem 7-Cylinder(s) will not retract.

Cause	Solution
Check the system pressure; if the pressure is zero, the control valve is releasing pressure and the problem may be in the cylinder(s), mechanical linkage connected to cylinder(s), or quickdisconnect couplings.	Check the cylinders for broken return springs and check couplers to ensure that they are completely coupled. Occasionally couplers have to be replaced because one check does not stay open in the coupled position.
Inadequate air pressure (air motor only).	Increase air pressure.

Problem 8-Pump delivers excess hydraulic fluid pressure

Cause	Solution
Pressure gauge is not accurate	Calibrate gauge
Relief valve not properly set	Reset the relief valve.

Problem 9-Automatic valve will not release pressure

Cause	Solution
Sticking piston	Remove, clean and polish
High pressure hydraulic fluid is leaking past the low-to-high pressure check. This hydraulic fluid leaks back to the piston in the automatic valve, keeping the piston closed	Seat the ball check. Inspect and replace any faulty components.

spx power team hydraulic pump parts list

A good way to keep and transport your air compressed is the SPX power team hydraulic pump. It can hold up to five (5) cubic feet of air at a time, so you will have enough for many jobs. Additionally, it has an accessible pressure gauge for indicating the amount in the tank.

This 5 cubic foot compressor has a 5 horse power engine that runs quietly but it can generate as much as 200 psi. This means that it does not only fill tires or blow up basketballs, but also other huge things like mattresses and rafts. It would as well turn off automatically if pressure goes too high or low thus stopping damage to your equipment or yourself from occurring full stop

spx stone hydraulic pump wiring diagram

The diagram in the figure below is the wiring diagram for the SPX stone hydraulic pump. The SPX stone hydraulic pump has a basic control circuit consisting of two switches, two relays and several other components. Below is a simple schematic diagram showing how the control circuit for Stone’s Hydraulic Pump operates:

A motor that is electrically connected to a voltage source through its terminals powers the above mentioned SPX stone hydraulic pump. This gearbox driven by the motor transmits power to a piston enclosed in a cylinder. When this cylinder rotates, there are high pressures produced at its opposite end which can be used for lifting or lowering heavy loads among others. It is thus possible to rotate this piston at different speeds and generate pressure using various voltages and given amounts of current supplied through motor terminals.
