ANGULAR TIGHTENING


APPLIED MODELS: All Models


SERVICE INFORMATION:


It is important that some engine parts are tightened using an angulartightening method rather than the exclusive use of the torque setting method because the tightening force (axial bolt force) which occurs using the torque setting method can result in "bolt stretch" or breakage. To assure satisfactory maintenance of the engine and to reduce the possibility of "bolt stretch" or breakage, Infiniti recommends that the angular-tightening method be used rather than the torque setting method whenever the appropriate Service Manual indicates application of this method.





A suitable angle wrench can be obtained from the Kent-Moore and the Snap-On Companies.
