SERVICE INFORMATION

PRECAUTIONS

Caution

INFOID:0000000001327509

Observe the following precautions when disassembling and servicing drive shaft.
• Joint sub-assembly does not disassemble because it is non-overhaul parts.
• Perform work in a location which is as dust-free as possible.
• Before disassembling and servicing, clean the outside of parts.
• Prevention of the entry of foreign objects must be taken into account during disassembly of the service loca-

tion.

• Disassembled parts must be carefully reassembled in the correct order. If work is interrupted, a clean cover

must be placed over parts.

• Paper shop cloths must be used. Fabric shop cloths must not be used because of the danger of lint adhering

to parts.

• Disassembled parts (except for rubber parts) should be cleaned with kerosene which shall be removed by

blowing with air or wiping with paper shop cloths.
