Replacing the housing screw
Required tools and resources
– Hand-held drill
– Drill bit (> 19 mm)
– 90° countersink bit (VIB 8.694)
– Thread tap M8 or UNC 5/16-18
– Torque wrench with 19 mm / 3/4" hex socket
– Compressed air for cleaning out the hole
– Solvent for degreasing
– Threadlocker (LOCTITE 243)
Select the point of installation
• The drilled hole must have direct connection to
the bearing carrier if the sensor should measure
shock pulse signals.
• Minimum distance between the drilled hole and
protruding edges of the housing must be 35
mm (A'). Allow adequate clearance to attach
the wrench.
Prepare mounting bore
• Remove housing cowling (B').
• Contersink hole: 90° / 3 mm deep (C').
• Blow out the hole.
• Bore out housing cowling, d > 19 mm (C'). VIB-
CODE bolt and cowling must not be in contact
after mounting. The cowling is held in place by
the locking nut only!
Mount stud
• Clean the contact surfaces of the stud and the
machine with solvent.
• Allow contact surfaces to dry.
• Thinly apply LOCTITE 243 to improve signal
transmission.
• Affix the protective cap to the stud and, if avail-
able, insert the code ring into the stud.
• Reinstall the cowling.
• At the appropriate location, the VIBCODE stud
is connected to the cowling as follows:
• Screw in the stud and tighten with a torque
wrench (11 Nm, D').
• Then tighten the locking nut against the cowl-
ing (E').
• Check the stud for tight mechanical fit.
