– Tightening Screws With Torque Wrench
Fit the screws by hand with a T-bar wrench or similar to allow rapid installation then tension the screws
using a calibrated torque wrench immediately.
After using the activator spray the retaining
compound will cure quickly so ensure this step is carried out right away!
A second person is necessary to hold the crank so that it does not rotate while tightening these screws.
Figure 195 (left) shows a screwdriver being used to hold the ring gear on the flywheel, locking the
crank. Alternatively a finger bar (Figure 28) may be used. The second person will also need to help
hold the engine steady. Trying to do this job alone is impractical and may compromise the job, resulting
in an in-flight failure.
Tension the screws in a standard diagonal tightening pattern. Torque all screws to the value given in
Table 9, using a standard diagonal tightening pattern.
Lock-wire may be applied. If it is used the screws must be wired in pairs per Section 3.9. Loctite 620 is
an extremely strong retaining compound and if the above procedure is followed correctly it is more than
strong enough to be used on its own without lock wire.
Allow the retaining compound time to cure (refer to manufacturer specifications) before starting the
engine
