For 7" bore cylinders and larger, the tie
rods are given an initial torque, the tie
rods are heated, and then the tie rod
nuts are turned a calculated amount.
First torque all 4 tie rod nuts to 200-250
foot pounds. Measure the cylinder to
obtain length L, consult the chart for the
proper number of turns or fractions (in
12ths). The figures in Column 1 shown
in 12ths corresponds to the points and
flats of the hex nut (see illustration).
The piston rod of the cylinder should be
either fully retracted or fully extended
prior to heating. Place an asbestos sheet
between the tube and tie rod and heat to
800°F for as long a length as possible.
When the distance between the cylinder
heads is 18" or less, do not heat closer
than 3" of either head. Tie rods should
be heated and tightened in cross corner
rotation and in steps up to full tension.
Allow the tie rods to cool before testing
or installation.
