Installation available at our shop in Bacliff, Texas. Please contact us for more information, or to schedule an appointment.

Use only bonded rubber/metal washers to seal the fittings in the pump. DO NOT use tapered adapters, sealing compound or P.T.F.E. tape.
Ports marked 'A' and 'B' are the service line connections to the ram (one is used, one is plugged), the pipe work and connections must be suitable for a 100 bar working pressure minimum rating.
The port marked 'R' is the reservoir or balance line and must be connected.
DO NOT plug this port--damage and failure could result.
Ensure that no dirt enters the system during the installation, be certain that all pipes and fittings are cleaned before connecting up.
Hydraulic Fluid:
Good quality 10 to 40 cst hydraulic mineral oil is recommended.
Power steering or Automatic transmission fluid can be used (Dexron/Mercon etc.).
The pump must not be run without oil.

 Pump Installation and Service Instructions:                                                                                                          Pump Size Maximum flow output at no load is indicated on the rating plate. Check the voltage shown is correct output. Locate pump away from high temperature, vibration, and moisture exposure when possible. Mounting the unit on a flimsy surface can transmit and amplify undesirable noise. As in common with other electrical equipment, contact with water and excessive humidity must be avoided. Keep the cable and pipe work runs as short as practically possible. Any attitude of mounting may be used but 'motor up' is advantageous. This unit should not be positioned in a confined area where there are flammable gases. Hydraulic Connections The 'A' and 'B' and 'R' ports are G1/4(BSP) parallel threaded, DO NOT USE tapered pipe threaded fittings. Our pump fittings use o-ring seals and no thread sealant or sealer should be used. 

40MM cylinder dimensions:

With a minimum of moving parts and top quality precision engineering the pump will give many year of trouble free service. Should service replacement seals be required, a kit is available from your nearest dealer under the following part code PR-sk
During disassembly carefully note the order of the components and keep everything clean, especially the pump faces with the plastic shim gasket or o-ring. When re-assembling, lubricate the check valve piston and gears with hydraulic fluid and ensure that all parts move freely. A smear of grease on the o-rings will aid assembly without damage.
Evenly torque the four M6 pump socket head cap screws to 10 lbs/ft (13.5Nm). The gears must turn easily at this stage.
Inspect the motor brushes every 500 hours, or annually, for wear. Replacement motor brushes are available from your dealer. State the serial number of your unit when ordering. Be sure to clean out all loose carbon before fitting new brushes. Electric motor cleaner recommended. If fluid has entered the motor, degrease the brush gear and commutator before running the unit, otherwise arcing will reduce brush life.

Trouble Shooting

1) Motor does not run:check electrical connections:check fuse/trip rating:check motor brushes


2) Motor runs, but no ram movement: check for air in system. Check for incorrect hydraulic connections. Check there is sufficient fluid in the system. Check that the relief valve is set correctly (see below). Check the drive coupling between pump and motor.


3) Excessive noise:check for air in system:check the motor for damage

To adjust relief valve, loosen jam nut and turn in Allen screw 1/4 to 1/2 turn to increase pressure. Adjust until there is just enough pressure to lift vehicle plus an 1/8 turn. The pump has 2 pressure ports, one is plugged, adjust the port that is connected to the system.
