Routine Maintenance
Prior to any maintenance it is necessary to have the following data.

The date that the lubricator was last maintained.

The final depth of the reservoir piston when the lubricator was last maintained.

The plunger height when the lubricator was last maintained.

Any works that were carried out when the lubricator was last maintained that could change the
grease output.

Any work that was identified but not carried out on the previous visit.
7.1 Measuring the Reservoir
7.1.1 This measurement is the only true guide to how much grease the lubricator has used since
it was last visited. It is necessary to have the previous recordings of the last inspection, this
will enable you to make judgements and carry out corrective action if needed without any
guesswork.
7.1.2 Using a ruler, insert it into the centre hole in the front cover of the reservoir, making sure
that the side of the ruler is touching against the side of the hole and that the ruler is at the
same angle of the reservoir (See Figure 4).
7.1.3 When the ruler stops at the rear most face of the piston, check exactly the measurement
(in millimetres) against the face of the front cover at the centre hole.
Figure 4
7.1.4 Record this measurement and compare it to the data that you have brought to site.
7.1.5 By subtracting the final measurement recorded from the last time the lubricator was
maintained from the measurement you have recorded this time would give you the grease
used in millimetres.
7.1.6 The type of lubricator, its installation and rail traffic will determine the volume of grease
used since the lubricator was last maintained. Figure 4 shows Whitmore Rail reservoir
(Part No. LCS102-01) where 1mm of piston displacement equates to 0.12kg of grease.
7.1.7 However do not make any alterations at this stage, as other reasons for incorrect grease
outputs may be the cause.
