CHAPTER 3 REPAIR PROCEDURES
3.2.7 Load Cell (MFR) Replacement (Cont.)
Load Cell Kits are available for replacement purposes for all AV and AS model balances. Each Kit is
assembled and consists of metal base plate, a Load Cell mounted to the base plate and a package of
labels. Check the label on the balance and verify the capacity and model before ordering a new load
cell kit. Figure 3-23 illustrates a typical MFR load cell location.
NOTE: Replacement MFR Load Cells are not supplied with InCal mechanisms. When replacing some
InCal Load Cells, it is necessary to remove the InCal weight arm from the old Load Cell and install it
on the new Load Cell.
The following procedures describe the disassembly of the MFR load cells in a progressive manner.
When the part that has been determined to be defective is reached, it may be replaced according to
the procedure it is described in. The procedures are not stand- alone, you must start from the beginning.
CAUTION
Extreme care must be exercised so as not to twist or
deform the Load Cell in any way. Do not drop or hit the
Load cell. Any damage to the Load Cell can render it
inoperative.
1. Remove the Top Housing in accordance
with the procedures in paragraph 3.2.1.
2. Remove the Load Cell Shield by grasping
the sides and pulling upwards.
3. Remove the 4 screws and washers that
secure Load Cell to the Bottom Hous-
ing. See Figure 3-23. Remove the Load
Cell.
4. Disconnect the cable(s).
5. Install the replacement Load Cell using
the 4 screws previously removed and con-
nect the flexible cables.
