Lubrication And Reassembly - Casio PRT-40C Repair Manual

2) Place all the component parts, except for the rotor, in
the cleaning fluid and clean each part with a cleaning
brush. Clean the areas around lubrication points par-
ticularly carefully.
3) Component parts may also be cleaned by pouring
cleaning fluid into an ultrasonic cleaner instead of per-
forming steps 1) and 2) above.
4) Never clean the rotor with cleaning fluid. Remove
any dust and metal particles using a Rodico. (Fig. 15-
7)

15-4-3 Lubrication and Reassembly

Once cleaning has been completed, reassemble each part.
Although the order of assembly is basically opposite that of disassembly, with respect to the details of
the assembly procedure, assembly should be performed according to the assembly procedure de-
scribed in the exploded view of the service manual for each module/with movement.
When assembling the train wheel side in particular, installing all of the gears and so forth and
covering with the bridge/train wheel check that each gear and rotor is securely installed in the proper
hole while viewing the module/with movement from the side with the screws still loose.
If the shaft has shifted out of position from the hole, adjust the position of the shaft with a pointed rod
such as an oil injector so that all gears are aligned at the proper positions.
In addition, lubricate the plate/main, bridge/train wheel, cannon pinion with driving wheel ass'y and
lever/setting. Both oil and grease are used for lubrication.
When using oil, place a suitable amount of oil to an oil pot, transfer that oil to the oil injector and drop
onto the movement.
The following indicates important points to be remembered regarding lubrication.
