PRECAUTIONS
PRECAUTIONS
PFP:00001
CautionEDS00060
Observe the following precautions when disassembling and servicing drive shaft.
lPerform work in a location which is as dust-free and dirt-free as possible.
lBefore disassembling and servicing, clean the outside of parts.
lThe disassembly and service location must be clean. Care must be taken to prevent parts from becoming
dirty and to prevent the entry of foreign objects.
lDisassembled parts must be carefully reassembled in the correct order. If work is interrupted, a clean
cover must be placed over parts.
lPaper shop cloths must be used. Fabric shop cloths must not be used because of the danger of lint adher-
ing to parts.
lDisassembled parts (except for rubber parts) should be cleaned with kerosene which shall be removed by
blowing with air or wiping with paper shop cloths.
Precautions for Brake SystemEDS0 00 I2
lWhen installing rubber parts, final tightening must be carried out
under unladen condition* with tires on ground.
*: Fuel, radiator coolant and engine oil full. Spare tire, jack,
hand tools and mats in designated positions.
lUse flare nut wrench when removing or installing brake tubes.
lAfter installing removed suspension parts, check wheel align-
ment and adjust if necessary.
lAlways torque brake lines when installing.
