STUD BOLT INSTALLATION
CAUTION
■ Thoroughly clean the Stub Bolt threads on screw holes in the block.
■ The Cylinder Block condition will change when the torque tightening is not done to the recommended specified
values. This affects the Bolts original design function which can lead to complications later.
■ Use a Tap tool to clear and correct all threads in the block. This will assist in securing the correct clamp force.
① Apply the assembly grease on the Nut surface
face & threads, prior to assembly.
② Spread Thread Lock paste on the threads of the
bolt that will be inserted into the block.
③ Fix the nut on the upper side of the Bolt in
the double nut configuration.
④ Tighten with a Torque Wrench.
⑤ Remove the double Nut.
