Safety precautions
Read this instruction for use fully. Follow all safety precautions to avoid personal
injury or property damage during equipment operation. SKF cannot be responsible
for damage or injury resulting from unsafe product use, lack of maintenance or
incorrect equipment operation. In case of any uncertainties as regards the use of
the equipment contact SKF.
Failure to comply with the following could cause equipment damage and personal injury.
• Do ensure that the equipment is only operated by trained personnel.
• Do wear proper personal protective gear, such as eye protection and protective
gloves, when operating the equipment.
• Do inspect the equipment and all accessories carefully before use.
• Do not use damaged components or modify the equipment.
• Do use clean recommended hydraulic oils (SKF LHMF 300, LHDF 900 or similar).
• Do not use glycerin or water based fluids as a pressure medium.
Premature equipment wear or damage can result.
• Do not use the equipment above the stated maximum hydraulic pressure.
• Do not adjust safety valves to work at pressures above the maximum
working pressure.
• Do not extend the handle in order to reduce the required force to reach maximum
pressure. Use hand pressure only.
• Do not use the pumps with accessories, which are rated below the maximum
working pressure of the pump.
• Do use a pressure gauge to monitor the oil outlet pressure.
• Do ensure that all the air has been removed from the hydraulic system before
pressurising the hydraulic system.
• Do prevent the workpiece (e.g. bearing, gearwheel or similar item) from being
forcibly ejected upon sudden release of pressure (e.g. by use of retaining nut).
• Do not use damaged hoses. Avoid sharp bends and kinks when connecting hoses.
Sharp bends and kinks will internally damage the hose leading to premature failure.
Applying pressure to a damaged hose may cause it to rupture.
• Do not lift the equipment by the hoses or couplings.
• Do follow local safety regulations.
• Do service the equipment by a qualified hydraulic technician or SKF Repair Centre.
• Do replace worn or damaged parts with genuine SKF parts.

1. Description
The 729124 has a maximum pressure of 100 MPa (14 500 psi) and delivers a volume
per stroke of 0,5 cm3 (0.03 in3). The pump is suitable for SKF hydraulic nuts (≤ HMV 54),
and for mounting or dismounting bearings or components with an interference fit applying
the SKF Oil Injection Method, where a maximum pressure of 100 MPa is required.
The pump is supplied with a 1,5 metre long, high pressure hose with quick connection
coupling. Mating quick connection nipple for attachment to the workpiece is included. The
pump is filled with SKF mounting fluid LHMF 300 and comes with an additional 1 litre can
with the same fluid. Everything is packed in a sturdy plastic case. The pump has an over-
pressure valve and a pressure gauge. The release valve is an integrated part of the pump
head.

3. Operating instructions
a) Check oil level by unthreading the container plug on the rear end of the container.
Make sure there is enough of oil for your complete operation. For mounting
bearings with the SKF oil injection method, or by means of an hydraulic nut, it is
recommended to use an oil with a viscosity of approximately 300 mm2/s
(1 400 SUS) at the operating temperature. For dismounting bearings, we
recommend to use an oil with a viscosity of approx 900 mm2/s (4 100 SUS) at
operating temperature.
b) Hold the pump horizontally or slightly tilted forwards in order to secure oil supply.
c) Close the release valve on the right hand side of the pump without using force.
d) Screw the quick connection nipple (G1/4) into the application.
e) Connect the hose to the nipple by gently withdrawing the snap-ring on the quick
connector. The hose is disconnected in the same manner.
f ) Continue pumping until necessary pressure is reached for your application. Maximum
pressure is 100 MPa (14 500 psi) at which pressure the safety valve will open.
g) Open the release valve, allowing superfluous oil to return to the oil container.

4. Maintenance
4.1 Replacing the oil
When replacing the oil or after maintenance, make sure no air is trapped in the system.
This should be checked before attaching the hose to the application by making sure only
air-free oil comes out of the hose when pumping. Only use clean, recommended hydraulic
oils.
4.2 Cleanliness
Keep the pump clean from dirt and metal particles in order to avoid excessive wear.
