1. GENERAL INFORMATION/TROUBLE DIAGNOSIS
The length of bolts and screws for
assemblies, cover plates or boxes is different
from one another, be sure they are correctly
installed. In case of confusion, Insert the bolt
into the hole to compare its length with other
bolts, if its length out side the hole is the
same with other bolts, it is a correct bolt.
Bolts for the same assembly should have the
same length.
Tighten assemblies with different dimension
fasteners as follows:
Tighten all the fasteners with fingers, then
tighten the big ones with special tool first
diagonally from inside toward outside,
important components should be tightened 2
to 3 times with appropriate increments to
avoid warp unless otherwise indicated. Bolts
and fasteners should be kept clean and dry.
Do not apply oil to the threads.
When oil seal is installed, fill the groove with
grease, install the oil seal with the name of
the manufacturer facing outside, check the
shaft on which the oil seal is to be installed
for smoothness and for burrs that may
damage the oil seal.

Remove residues of the old gasket or sealant
before reinstallation, grind with a grindstone if
the contact surface has any damage.
The ends of rubber hoses (for fuel, vacuum,
or coolant) should be pushed as far as they
can go to their connections so that there is
enough room below the enlarged ends for
tightening the clamps.

Rubber and plastic boots should be properly
reinstalled to the original correct positions as
designed.
Boots
The tool should be pressed against two
(inner and outer) bearing races when
removing a ball bearing. Damage may result
if the tool is pressed against only one race
(either inner race or outer race). In this case,
the bearing should be replaced. To avoid
damaging the bearing, use equal force on
both races.
Both of these examples can result in bearing
damage.
