Fitting the main transformer TC02
When replacing the main transformer, it is also necessary to replace the transformer core.
This is because the core is bonded with adhesive, and cannot be disassembled.
Adhesive and tape are required when fitting a new transformer, in addition to the coil and
core. Part numbers for the requisite adhesive and tape are shown as Item 428 in the spare
parts list.
1. Transfer wire 020 and connector XS17 to the new transformer. If the wire needs to be
replaced, it is important to use the correct type of insulation (Teflon)

2. Apply a layer of tape (t) to each of the three airgaps in the transformer core. Use the tape
specified in the spare parts list.
3. Apply Loctite 648 (see the spare parts list) to the contact faces between the cores and
between the core and coil. Secure the transformer in position in the machine. The
adhesive takes about 20 minutes to harden.
