2.7 Hydraulic oil
The pump is filled with SKF Mounting Fluid
LHMF 300.
Dirt and metal particles in the oil can cause wear of
the piston mating surfaces, leading to excessive oil
leakage and permanent damage to the THHP 300.
The recommended oil cleanliness level should meet
or exceed ISO 4406:1999 20/18/15.
Using fluids or oils, other than SKF mounting and
dismounting fluids, can cause corrosion and/or
damage to mating surfaces.
Do not mix fluids or oils of different brands.
Use appropriate oil with a viscosity of 300 cSt, at
operating temperature, to mount bearings and
similar items using the SKF Oil Injection Method.
SKF hydraulic fluids used in our pumps are
especially formulated for the mounting and
dismounting processes. In the table below is an
overview of what to use when:
Job type Environment temperatures SKF Oil
Mounting 0 °C (32 °F) to 35 °C (95 °F) SKF Mounting Fluid, LHMF 300
35 °C (95 °F) to 45 °C (113 °F) SKF Dismounting Fluid, LHDF 900
Dismounting 0 °C (32 °F) to 10 °C (50 °F) SKF Mounting Fluid, LHMF 300
10°C (50 °F) to 45 °C (113 °F) SKF Dismounting Fluid, LHDF 900
