2. While assembling the rotor, ensure that the rubber ring has taken proper seat in its
place. This is necessary for proper sealing of rotor assembly.
3. Take care with the centrifuge housing and rotor body. They are made of aluminium, hence
are susceptible to damage due to accident.
4. Always ensure that the arrow marks on rotor cover and rotor are matched after
assembling the rotor. See Fig 5.1.5.6 above. The rotor body is dynamically balanced.
Mismatch of arrow marks on rotor cover and rotor will result in excessive vibrations of
the cleaner and part breakage.
5. The rubber ring is made of Viton rubber. Use genuine spare rubber ring only. Rubber
ring of any other material will not give desired performance.

Do not over tighten the top nut. Tighten just enough to prevent leakage of oil from
centrifuge cover and housing. Over tightening top nut will damage the threading in
centrifuge housing and damage the centrifuge permanently.
Use 1.2 kg-m torque for tightening of centrifuge cover
.

Do not hold the rotor nut in clamping device like bench vice as shown. Extra
clamping pressure on rotor nut may result in damaging the circularity of upper bush
and will result in permanent damage to rotor assembly. See Fig 5.1.5.7 above
Do not open or tamper with the valve assembly. The valve assembly is preset for
opening oil pressure in engine’s oil gallery. If the setting is lost or the valve
assembly is damaged, there is risk that your engine will not get enough oil or the
centrifuge will not function properly. See Fig 5.1.5.8 above
