1-4 GENERAL INFORMATION
Generally, when installing a part with several bolts, nuts,
or screws, start them all in their holes and tighten them to
a snug fit. Then tighten them according to the specified se-
quence to prevent case warpage or deformation which can
lead to malfunction. Conversely when loosening the bolts,
nuts, or screws, first loosen all of them by about a quar-
ter turn and then remove them. If the specified tightening
sequence is not indicated, tighten the fasteners alternating
Incorrect torque applied to a bolt, nut, or screw may
lead to serious damage. Tighten fasteners to the specified
torque using a good quality torque wrench. Often, the
tightening sequence is followed twice-initial tightening and
final tightening with torque wrench.
Use common sense during disassembly and assembly,
excessive force can cause expensive or hard to repair dam-
age. When necessary, remove screws that have a non
-permanent locking agent applied using an impact driver.
Use a plastic-faced mallet whenever tapping is necessary.
Hardening, shrinkage, or damage of both gaskets
and O-rings after disassembly can reduce sealing per-
Remove old gaskets and clean the sealing
surfaces thoroughly so that no gasket material or other
material remains. Install new gaskets and replace used
O-rings when re-assembling
Liquid Gasket, Non-permanent Locking Agent
For applications that require Liquid Gasket or a
Non-permanent Locking Agent, clean the surfaces so
that no oil residue remains before applying liquid gasket or
non-permanent locking agent. Do not apply them exces-
sively. Excessive application can clog oil passages and
cause serious damage.
