③
When installing an oil seal onto a shaft, apply
lubricating oil or grease to its seal lip and the
mounting surface of the shaft. For a double-
lip type, fill grease by 1/3 to 1/2 of the space
between the lips.
When inserting an oil seal into a case, use care
to damage the seal lip. It is good practice to use
a suitable conical sleeve.
4. Using LOCTITE
(1) Procedure for using LOCTITE
①
Clean or degrease the surface of parts you are going to apply LOCTITE, using trichloroethylene,
acetone, ether or alkaline solution.
②
Blow dry them with compressed air or allow to air dry at room temperature sufficiently.
③
Apply specified LOCTITE.
(2) Removing parts
When removing parts which were installed with the application of LOCTITE, use tools such as a
spanner, wrench, and pulley remover.
If you fear that a part may break due to the effect of LOCTITE if forcibly removed, heat the part to
200 to 250°C [392 to 482°F] with a soldering iron or gas burner.
Remember that parts are very hot after heating. Use caution not to get burnt when
removing them.
(3) Reinstalling parts
①
When destroyed, LOCTITE remains as white powder on the threads of bolts. You can apply a
new coat of LOCTITE again over their surface.
Note: For example, if a bolt turns slightly due to bolt torque checking, remove the bolt and apply
LOCTITE again and reinstall.
②
If LOCTITE is used for the surface of a flange, it is necessary to remove hardened LOCTITE with
a wire brush when reinstalling the flange.
5. How to use a power wrench
Power wrenches have their respective torque multiplying factors. Refer to the product catalog of
each power wrench.
It should be noted that a value obtained by multiplying the output torque of a torque wrench by the
multiplying factor of a power wrench is not necessarily an output torque.
Remember this especially when the tightening torque is strictly specified.
