Step 6: Assembly of cylinder mount, Figure #7, to vertical column, Figure #3 as shown on
drawing 50979.
a.) Remove the cylinder mount from the shipping crate using a forklift or
bridgecrane.
b.) Select six (6) M20 "I" taper washers, item 12 , six (6) 3/4" flat washers, item
54 , and twelve (12) M20x2.5 nuts, item 15 .
c.) Lower the cylinder mount and carefully align and slide over the six (6) M20 bolts
protruding through the vertical column. The cylinder mount must be oriented so
that the cylinder pin hole is located at the bottom rear corner of the cylinder
mount.
d.) Now place the six (6) M20 "I" taper washers, the six (6) 3/4" flat washers, and
the six (6) M20 nuts respectively on the bolts. Make certain the nuts are tight by
applying 367 foot-lb of force using a torque wrench. Now place one (1) each
M20 nut in addition to the existing nuts and torque to ensure that the fasteners
will remain secure during operation of the test stand. See drawing 50979 for
details and orientation.

Step 7: Assembly of winch to tester frame. See assembly on page 20 and drawing 50979
page 26.
a.) Select the components as shown on the winch assembly drawing page 20.
b.) Assemble the RH and LH pulley mounts, items 1 and 4 page 20, and pulleys
with components, items 6 , 7 , and 9 , prior to attaching them to the tester
frame. Be sure the mounting holes are oriented correctly as shown in the ass-
embly drawing page 20. The ends of the frame with two (2) mounting holes
are located to the front of the tester and the ends with the single mounting holes
to the rear. Place all three (3) pulleys, pulley spacers, and pulley bushings in
position and attach by using three (3) M12x70mm long bolts, item 50 , three (3)
M12 lock washers, item 47 , and three (3) M12x1.75 nuts, item 46 , as shown on
assembly drawing 50979. Do not tighten nuts until after attaching to the tester
frame.
