5.15Lubrication

Remove the covers to the machine and lubricate all moving parts as indicated on the

Lubrication Diagram 5.15 and with lubricants specified in Table 5.15.

applying. Surplus oil should

be wiped off as it attracts dust

teeth marked “M”

Points to be observed while carrying out lubrication:

1. Use only the recommended grade of oil. Inferior grades should be avoided as

they may cause rust, material fatigue or blockage in oil holes

2. On locations of light pin movement, only a few drops of oil are required.

3. Use brushes to grease gear surface where heavy weight is applied.

4. Supply a thin layer of oil on all sliding surfaces and at times wipe with an oil cloth

to remove accumulated grit.

5. The slide chairs must be cleaned and lubricated with an approved dry lubricant at

each maintenance visit by the maintainer.

5.16Excess Ballast

Clear all ballast and foreign matter likely to foul the operation of the point machine to

ensure clearance around all moving parts of the points.

5.17Check Operation of Point Machine

Check smoothness and correctness of operation by switching several times using

manual operation, and finally by power operation.

5.18Overhaul

A fixed overhaul period cannot be set due to traffic movement frequencies and local

conditions. Overhaul periods must be determined by inspection during maintenance, to

determine the amount of wear on the gears, throw bar, lock slide bearing surfaces and

the general condition of the mechanism. General overhaul involves complete stripping,

cleaning and inspection, replacement of worn and faulty parts and reassembly as

discussed in appropriate sections of this manual.
