GENERAL INFORMATION
Tightening Sequence
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 sequence 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 quarter turn and
then remove them.
Tightening Torque
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.
Force
Use common sense during disassembly and assembly, excessive force
can cause expensive or hard to repair damage. 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.
Gasket, O-ring
Hardening, shrinkage, or damage of both gaskets and O-rings after
disassembly can reduce sealing performance. Remove old gaskets and
clean the sealing surfaces thoroughly so that no gasket material or other
material remains. Install the new gaskets and replace the used O-rings
when re-assembling.
