Transport Cylinder Support Brace
The transport-lift cylinders are equipped with cylinder sup-
port braces to prevent cylinder buckling during transport.
These support braces must be properly assembled to sup-
port transport-lift cylinders without binding or placing undo
side loads on cylinders.
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. See Figure 3-9.
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 center 1/2-inch jam nut.
5. Install spring (6) and 1/2-inch nylock nut (7). Tighten
nut to compress spring to a 1 1/4 inches (3.18 centi-
meters).
