Torque and Locking Agent
The following tables list the t ightening torque
for the major fasteners requiring use of a non
-permanent locking agent or liquid gasket.
Letters used in the “ Rem arks” column m ean:
AL: Tighten the two clamp bolts alternately
two times to ensure even tightening
torque.
G: Apply grease to the threads.
L: Apply a non-permanent locking agent to
the threads.
MO: Apply molybdenum disulfide grease oil
solution.
O: Apply oil to the threads and seating sur-
face.
R: Replacement Parts
S: Tighten the fasteners following the speci-
fied sequence.
Si: Apply silicone grease (ex. PBC grease).
SS: Apply silicone sealant.
The table below, relating tightening torque to
thread diameter, lists the basic torque for the
bolts and nuts. Use this table for only the bolts
and nuts which do not require a specific torque
value. All of the values are f or use with dry
solvent-cleaned threads.
