1. GENERAL INFORMATION
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.

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.
Lubricate the rotation face as assembling.
Check if positions and operation for installed
parts is in correct and properly.
