Technical information

A By a press
Block up the loadcell (12) on the base
of the press (13) using packing under
the floating sleeve. This is to ensure
that the body will move downwards,
thus breaking the seals when pressure
is applied to the loadcell button.
When parting the loadcell in the press,
it is necessary to ensure that the
floating sleeve has been packed
sufficiently to move downwards when
pressure is applied to the loadcell
button, thus breaking the seals.
By using a steel bar, gradually roll the
rims of the floating sleeve, thus
resealing the loadcell.
B By a lathe
The diameter of the floating sleeve can
be turned down on a lathe so as to
reduce the thickness to approx.
0.25mm (0.010"), at which stage the
rims of the floating sleeve may be
broken away, releasing the sealing
rings and inner parts.
Renew sealing rings and floating
sleeve, then reassemble, clamp the
body of the loadcell in the lathe and
rotate at slow speed.
The floating sleeve can be turned off in
the lathe. First clamp the body of the
loadcell in the chuck and by taking light
cuts reduce the diameter by 2.5mm
(O.1”). At this stage it should be
possible to split the outer skin,
releasing the inner parts.
Resealing the loadcell
With all parts assembled in position, apply
a coating of Goodyear Pliobond around
the outside edge of sealing rings.
Clamp the loadcell body in the chuck and
gradually roll both edges of the floating
sleeve, thus locking the inner parts in
position.
