15-4 Disassembly, Cleaning, Lubrication and Reassembly of Module/with movement
Tool used
15-4-1 Disassembling
Although disassembly is basically performed in the order of PCB ass’y, coil ass'y, minute train side,
correction part and train wheel part, with respect to the details of the disassembly procedure, each
part should be disassembled one at a time according to the disassembly procedure described in the
exploded view of the service manual for each module/with movement.
For those persons who are unfamiliar with the disassembly procedure, make the repair work as fol-
lows.
a) Lay the parts out in the order they are disassembled in order to makes assembly work
easier.
b) Make the sketches of the movement while the movement is disassembled in order to make
clear the position of each components on reassembling.
When disassembling, perform work while checking each part for damaged locations and the
presence of dust and dirt.
15-4-2 Cleaning
Once disassembly work is completed, clean each
component part.
1) Pour some cleaning fluid into a container such
as a Petri dish. Use benzene or isoprophyl
alcohol when cleaning metal movements, and
isoprophyl alcohol when cleaning plastic move-
ments. (Never use benzene to clean plas-
tic movements.) (Fig. 15-6)
