D) Installation instructions
Synchronising the adjustment screws
of the tensioning unit
Synchronisation is carried out with the tensioning unit removed.
Check that the pressure plates are fully pushed back against the
stops.
Lay the tensioning unit on a surface plate with the pressure plates
facing downwards.
Using a dial indicator with magnetic base, set the tip of the indica-
tor onto the clamp at "A". Set the indicator dial to
”0” (zero)
.
Move the mechanism now until the tip sits on the clamp at "B".
Note!
The dial indicator must remain stationary.
Lift the adjuster rod so that the toothed wheel runs free from the
bevel gear. Using the adjuster rod, turn the adjusting screw until
the indicator reads
”0” (zero)
.
Return the adjuster rod to its position. If the toothed wheel does
not mesh correctly with the bevel gear, lift the adjuster rod and
locate it inanother position on the adjuster screw. Keep trying
WITHOUT
turning the adjuster rod, until the toothed wheel and
the bevel gear mesh together correctly.
Check the measurements again at point "A" and "B" to make sure
that they are within
0 ± 0.2
mm of each other.
If the difference is more than
0.2
mm then a new synchronisation
must be carried out.
