CautionNDS000C0
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
location.
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 adher-
ing 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.
