Table20: Tightening torque (81152 / 81154)
1. Fit the new absorption element(81148) and flanges(81145 / 81146) with roll pins(81151)
and socket screws(81154).
Tighten socket screws(81154) crosswise. Observe the tightening torque.
2. Check value X = 15 mm +/- 0.1 mm along the circumference at four points (0°, 90°, 180°
and 270°).
If value X is not satisfied, unscrew the socket screws(81154) and repeat step one.
3. Fit the mounting plate(81149) with washers(81153) and hexagon-head screws(81152).
Observe the tightening torque.
4. Remove the filter silencer (see Fig.84: Installing the uncoupled filter silencer (see
Table57: Tightening torque (72054) →133).
