All parts should be thoroughly cleaned, paying
special attention to the engine oil passages, pis-
tons and bearings. Rotating parts and sliding parts such as piston,
bearing and gear should be coated with oil prior to
assembly.
Be careful not to let oil, grease or coolant contact
the timing belt, clutch disc and flywheel.
All removed parts, if to be reused, should be re-
installed in the original positions and directions.
Bolts, nuts and washers should be replaced with
new ones as required.
Even if necessary inspections have been made
in advance, proceed with assembly work while
making rechecks.
Remove or install engine in an area where chain
hoists, lifting devices, etc. are available for ready
use.
Be sure not to damage coated surfaces of body
panels with tools, or not to stain seats and windows
with coolant or oil. Place a cover over fenders, as
required, for protection.
Prior to starting work, prepare the following:
Service tools, clean cloth, containers to catch cool-
ant and oil, wire ropes, chain hoist, transmission
jacks, etc.
Lift-up or lower the vehicle when necessary.
Make sure to support the correct positions.
