READ THIS FIRST
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 extend the handle in order to reduce the required force to reach maximum
pressure. Use hand pressure only.
• Do not use the injector with accessories, which are rated below the maximum
working pressure of the injector.
• Do not use washers on sealing surfaces.
• 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 handle high pressure pipes. Oil under pressure can penetrate the skin,
causing serious injury. If oil is injected under the skin, seek medical attention
immediately.
• Do not use damaged high pressure pipes. Avoid sharp bends and kinks when
connecting pipes. Sharp bends and kinks will internally damage the pipe leading to
premature failure.
Applying pressure to a damaged pipe may cause it to rupture.
• Do not lift the equipment by the pipe 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. Application
The SKF oil injection kits 729101/300MPA and 729101/400MPA are used for pressure
joints of all sizes and applications, such as propellers, rolling bearings, couplings, gears,
pulleys, wheels, flywheels, where the surface pressure is less than 250 N/mm²
(350 N/mm² for kit 729101/400MPA).
The adapter block 226402 makes it possible to connect a high pressure pipe and pressure
gauge to the SKF oil injector 226400 E (alt. 226400 E/400).
The design of this adapter block assures a correct positioning of gauge and injector and
offers several possibilities of working position, such as on the floor, fixed in a vice or with a
G-clamp.

3. Assembly & operating instructions
If adapter block is to be used on a relatively flat surface,
put the telescopic steel pipe in corresponding slot of
adapter block. Lock it in position with the quick action
lock screw.
The adapter block can also easily be locked on the top
of a working bench by means of a standard G-clamp.
It can also be clamped in a vice.
Screw the oil injector on the adapter block until the
thread can be seen in the inside slot.
Screw the rectangular gauge adapter nipple into the
thread of the pressure gauge tightly, so that a good seal
is formed. Make sure the flat surfaces of the nipple are
aligned with the pressure gauge.
The use of a vice, with soft aluminium jaws, can greatly
simplify the mounting of the pressure gauge.
This nipple will remain on the gauge. There is no need
to remove the gauge from the nipple after using the
equipment.

Push the gauge adapter nipple into the top slot of the
adapter block.
Note:
To avoid misalignment the O-ring has to be located on
the flat part of the gauge nipple.
The O-ring has no sealing function, it only helps in
aligning the components.
The following operation should be done carefully.
The illustration shows how the seal will be achieved.
Screw the high pressure pipe nipple into the back of the
adapter block, while gently moving the gauge adapter
nipple in order to secure the correct position of the high
pressure sealing area.
Then screw the oil injector into the block until it is
touching the gauge nipple. Gently loosen and tighten the
pipe and oil injector until the oil injector is in the correct
position, then tighten the high pressure pipe.
Make sure all parts are properly aligned. Failure in doing
so will prevent proper sealing and will cause leakage.
The component design helps achieve an effective sealing
with a moderate tightening torque.

When the oil reservoir (K) is to be charged, the nozzle is immersed in oil and the piston
retracted by the handle. The oil will then be sucked into the reservoir.
To allow any air to escape, point the nozzle upwards and depress the valve ball slightly.
Screw the reservoir onto the injector, the ball is automatically depressed and the valve
opened.
Make a few strokes with the lever to displace any air trapped in the injector body and then
close the release valve firmly.
If the valve is not tight enough then it can be difficult to reach the maximum pressure.
Note: that the oil reservoir can be refilled without releasing the pressure from the pump.
The kit is now fully assembled and ready for use.
Ensure that no air is trapped in the system, by pumping
until air-free oil is released from the end of the high
pressure pipe. Thread the swivel nipple, on the high
pressure pipe, in to the application. If necessary, use any
of the connection nipples that are delivered with the set.

5. Recommended mounting and dismounting fluid
SKF mounting fluid
SKF LHMF 300/5 mounting fluid is recommended when mounting shrink-fitted
components with the SKF oil injection method.
The mounting fluid is recommended for use at a temperature of 18... 25 °C (64... 77 °F).
The fluid contains anti-corrosive additives.
SKF dismounting fluid
SKF LHDF 900/5 dismounting fluid is recommended when dismounting shrinkfitted
components with the SKF oil injection method.
The dismounting fluid should be used at a temperature of 18... 25 °C (64... 77 °F).
The fluid contains anti-corrosive additives.
Due to the high viscosity of the fluid it might be necessary to operate the pump slowly.
Oil cleanliness requirements
Dirt and metal particles in the oil can cause wear of the piston mating surfaces, leading to
excessive oil leakage and permanent damage.
The recommended oil cleanliness level should meet or exceed ISO 4406:1999 20/18/15.
Using fluids, other than oils or SKF mounting and dismounting fluids, can cause corrosion
and/or damage to the piston mating surfaces. Do not mix fluids or oils of different brands.
