Assembly oil: Several different lubricants and fluids are used in the construction of locomotive dampers.

2
00:00:07,000 --> 00:00:15,917
Assembly oils or greases are yellow, black, or white in color, and can be easily distinguished from the red hydraulic damping fluid.

3
00:00:15,917 --> 00:00:21,750
When the damper is new, the assembly lubricant may cause a slightly moist rod or body.

4
00:00:21,750 --> 00:00:27,333
If this occurs, simply wipe off the excess oil and return the damper to service.

5
00:00:27,333 --> 00:00:32,375
If a new damper has red oil droplets, the damper should not be installed.

6
00:00:32,375 --> 00:00:39,042
Sweating: For a long service life, it is necessary for the rod oil seal to remain lubricated.

7
00:00:39,042 --> 00:00:45,708
The continuous inward and outward movement of the piston rod may cause oil "sweat" from the rod oil seal.

8
00:00:45,708 --> 00:00:52,167
This loss of oil can be recognized by the outside of the damper being slightly moist and dirty.

9
00:00:52,167 --> 00:00:57,792
A slight oil sweating will not affect the damping force and the damper may remain in service.

10
00:00:57,792 --> 00:01:07,833
Droplets: If red droplets of oil are clearly formed or the damper body is wet with hydraulic fluid, the damper must be replaced.
