Disassembly and assembly of this machine, with inspection and change of vibrator oil included,
should be done on a horizontal surface area. Before disassembly and assembly, understand well
the normal assembly condition so that you will not make assembly error.
If oil seal, gasket, packing, O-ring or lock washer is disassembled, replace it with a new one each
time.
The contact surface between vibrating case and vibrator cover should be sealed with Packing or
O-ring. (Clean the contact surface and be careful about O-ring position when assembling.)
Apply Liquid Gasket (Three bond 1215 or equivalent) on the each side of packing of Case Cover.
When tightening bolts and nuts, tighten them according to the specified standard torque and
applying the screw lock agent (Loctite, etc.). For bolts and nuts with no specification, refer to the
“Tightening torque list”. (When applying screw lock agent, degrease and clean the screw part with
the brake cleaner, etc.)
Note) The bolts used on this machine are all of the right hand thread.
When disassembling and assembling, work in the maintenance shop without dirt and dust.
When the bolts applied the screw lock agent (Loctite, etc.) are difficult to loosen, they loosen
easily by heating them with a torch burner. Then, replace the heated bolt with a new one. It
should be a specified high tension bolt (genuine parts).
Use correct tools correctly.
