  1. Remove nut (2) and washer (3) from the mounting.
  2. Attach each mounting to the engine / installation brackets by means of fixing the nut (2), washer (3) and central buffer (4) handtight; simultaneous block the central buffer by applying a spanner to the hexagon.
  3. Lower the installation load onto the mountings.
  4. Loosen nut (2).
  5. Check that all central buffers (4) can be turned easily by applying a spanner to the top hexagon. If this is not possible, it will be necessary to partly remove the installation load, until the buffers can be turned freely. The central buffer should now be turned anti-clockwise (upwards) and the installation relowered onto the mountings. Check that all central buffers can be turned freely. If this is not the case then the above-mentioned procedure should be repeated. Where practical, the mountings should be allowed to settle for a minimum of 48 hours before any attempt is made to line up drives, pipe-work, etc.
  6. The suspended installation may now be levelled if necessary by means of jacking bolts, which can be placed into the tapped holes of the base casting of each mounting. Care must be taken, during levelling of the installation, to ensure that individual mountings are not overloaded. The variation in laden height should not exceed 2 mm and should ideally be less. The laden height can be measured between top and base casting at X, on two sides (see dim. sketch). The difference between the two sides of a mounting should not be more than 0,9 mm.

The central buffer working clearance for each mounting can now be set as follows:

  • Turn the central buffer clockwise (downwards) to the maximum lower position, until it contacts the filler plate or foundation.
  • Turn the central buffer two full turns (RD 113 - 1,5 turn) anti-clockwise (upwards) into its operating position (buffer will now have a working clearance of 6 mm).
  • Fasten nut (2), while simultaneously blocking the central buffer by applying a spanner to top hexagon. Place protective cap over nut. Further locking is not necessary.
  • Individual filler plate thickness can now be measured. Notice that the filling plate must at least have the dimensions of the mounting foot.

  1. Remove nut (2) and washer (3) from mounting.
  2. Place adjusting nut (5) in neutral position by means of rotating, until the distance from top of adjusting nut to the machined part of top casting is 25 mm.
  3. Attach each mounting to the engine / installation brackets by means of fixing the nut (2), washer (3) and central buffer (4) handtight; simultaneous block the central buffer by applying a spanner to the top of hexagon.
  4. Lower the installation load onto the mountings.
  5. Loosen nut (2).
  6. Check that all central buffers (4) can be turned easily by applying a spanner to the top hexagon. If this is not possible, it will be necessary to partly remove the installation load, until the buffers can be turned freely.

The laden height can be measured between top and base casting at X, on two sides (see dim. sketch). The difference between the two sides of a mounting should not be more than 0,9 mm.
  8. The adjusting nut (5) is meant to adjust the effect of creep on the alignment after a period of time.

The central buffer working clearance for each mounting can now be set as follows:

  • Turn the central buffer clockwise (downwards) to the maximum lower position, until it contacts the filler plate or foundation.
