a. Tightening Specifications
Use a reliable torque wrench to tighten the
parts listed to ensure
proper
tightness
with-
out straining or distorting parts. These speci-
fications are for clean and lightly lubricated
threads only
,.
dry or dirty threads produce in-
creased friction which prevents accurate meas-
urement of tightness.
