If cylinders are removed or inner-axle-slide blocks become
worn, assemble or adjust support braces as follows. Use
this procedure for both support bolts on the transport-lift
cylinders.
1. Assemble 1/2-by-5 1/2-inch, full-thread bolt (1) to cyl-
inder support brace (2), bolted to rod end cylinder
casting.
2. Screw on three 1/2-inch jam nuts (3) and one 1/2-inch
washer (4) as shown. Tighten first jam nut against cyl-
inder support (2) and run other two jam nuts on nearly
all the way.
3. Install cylinder with support bolts (1) extending
through bracket (5) on outer slide tube and pin both
base end and rod end.
4. Screw outer 1/2-inch jam nut out until 1/2-inch washer
(4) just touches bracket on outer slide tube. Do not put
pressure on the cylinder by tightening the 1/2-inch jam
nut. Once washer touches bracket, lock outer 1/2-inch
jam nut in place with centre 1/2-inch jam nut.
5. Install spring (6) and 1/2-inch nylock nut (7). Tighten
nut to compress spring to 32 mm (1 1/4 inches).

page 31.
When in storage, lower openers on a board or hard sur-
face. Apply a light coat of oil to exposed cylinder rods.
