How to pump rack ?

The need to pump Strut front of their immediate installation is usually due to the fact that the inner sleeve shock absorber is an air layer, and a shock absorber because this will not function correctly.Especially if it happens during transportation.And this can lead to malfunctions in the damper as noises or knocking during car movement, and as a result may fail the entire piston shock absorber system.When deciding how to pump rack before installation, should refer to the technology of pumping cartridges or twin damper struts.In addition, the pumping damper struts before installing them will reveal whether there are cases of jamming in the valve mechanism or other faults.Even in completely new arrangements.It is important to remember that when pumping a little damper struts valve mechanism of resistance fail, or output shaft speed difference is not a malfunction and cause for panic.This is especially true shock absorber gas-oil type.


damper struts Before pump new rack, it is necessary

to set up a rod and smoothly without jerking, compress until such time as the working surface of the stem is at the top of the glass, reaching 2-3 cm.

  • 2-3 seconds damper lock rod in a given position.
  • Gently and slowly pull the damper rod to its relaxed state.This is the easiest way how to pump Strut yourself.This process should be repeated 2 or 3 times.
  • After, you need to do a test procedure.Shock must be kept in an upright position, holding the stem upward.It is necessary to produce short sharp movement of the rod, and the best that he move smoothly, with no apparent failures.
  • Following the procedure of pumping damper struts, it will be shown in working condition, and you can replace the shock absorber.In addition, it is ways of how to properly bleed the stand will be able before setting allow you to identify the jamming of the valve mechanism or other faults, even a completely new mechanism.
  • racks of other types of shock absorbers pumping technology make the appropriate way.Shock is necessary to turn the stem down and squeeze the smooth motion without jerking.
  • In this position, shock absorber rod should be fixed for 2-3 seconds.
  • After that, you need to turn the shock absorber rod upwards, thus to fix the shock absorber in this position for 4-6 sec., Holding the rod.
  • necessary to smoothly push the stock up to the limit of its travel and repeat the algorithm 2-3.Complete
  • need to control performance.Shock must be kept upright rod upward.It is necessary to produce short sharp movement of the rod, while his movements should be smooth, with no apparent failures.
  • After you spend leveling control damper struts procedure, it is better to fix the rod in position up to the date of installation on a place in the car.
