When reworking the mounting hole, pay particular attention to the
centricity of:
- the hole,
- the thread and
- the sealing surface.
Pressure sealing takes place on the 45° beveled sealing surface and on the front
cylindrical section of the PT (see figures 06 and 07).
The sealing surface must be:
- correctly machined
- free from marks and rough edges
- free from solidified plastic residue.
6.2 Checking the mounting hole
- Paint the test bolt DYNISCO on the marked area
(figure 08, item 1) with marking ink up to the
thread.
Fig. 08: test bolt with marking ink
- Insert the test bolt in the mounting hole
- Twist it in by hand until the two sealing surfaces make contact.
- Remove and examine the test bolt.
The only acceptable abrasion of marking ink is at the sealing edge (45°), evenly (!)
over the entire circumference.
If the ink has been rubbed off in other places too:
- rework the mounting hole.
