Lift Switch Assembly
Refer to Figure 2
1. Remove the 1/2" x 5 1/2" long bolts (#28) nuts, flat
washers, and springs from the right hand transport
cylinder brace and insert the switch mount (#4), and
1/2" lock washer (#15), under the head of the bolt.
Position the mount and bolts back onto the brace
and reassemble the nuts, flat washers and springs
onto the brace. It is important that these support
braces are properly assembled to support the trans-
port cylinders without binding or placing undo side
loads on the cylinders. Whenever the 5 1/2" support
bolts are removed or the inner axle slide blocks be-
come worn, assemble or adjust the cylinder support
braces as follows.
a. Assemble the 1/2" x 5 1/2" long full thread bolt
(#28), 1/2" lock washer (#15), and the switch
mount (#4) to the cylinder support brace (#22)
bolted to the rod end cylinder casting.
b. Screw on three 1/2" jam nuts (#23), and one
1/2" washer (#24) as shown in . Tighten the first
jam nut against the cylinder support (#22) and
run the other two jam nuts on, nearly all the way.
c. With the cylinder properly installed, the support
bolts (#28) should extend through the bracket
(#27) on the outer slide tube when the base end
and rod end pins are in place.
d. Screw the outer 1/2" jam nut out until the 1/2"
washer (#24) just touches the bracket on the
outer slide tube. Do not put pressure on the cyl-
inder by tightening the 1/2" jam nut. Once the
washer touches the bracket, lock the outer 1/2"
jam nut in place with the center 1/2" jam nut.
e. Install spring (#25) and 1/2" nylock nut (#26).
Tighten nut to compress spring to a 1 1/4"
length.
Use this procedure for each of the two support bolts
on the transport cylinders.
2. Fasten the cylinder rod clamps (#3 & 6) to the clevis
end of the cylinder rod with two 5/16" x 1 1/4" bolts
(#16), lock washers (#18) and nuts (#19). The offset
of the clamp must be toward the right hand side of
the hitch as shown.
3. With the ramp of the push rod (#5), facing toward the
center of the hitch, insert it between the ears of the
cylinder rod clamp (#6), and bolt it in place with a
5/16" x 1 1/4" bolt (#16), two 5/16" USS flat washers
(#17), and nylock nut (#20). It is recommended to
bolt it through the lower-most hole in the push rod.
Only run the nylock nut far enough onto the bolt to
make full engagement of the nylon collar on the nut.
Do not cinch it down. The bolt and push rod must be
free to move in the slot of the clamp.
4. Slide the switch guide block (#2), over the push rod
and fasten it to the mount with two 1/4" x 2" long
bolts (#12), flat washer (#21), lock washers (#13),
and nuts (#14).
5. Bolt the plunger activated switch (#7), to the mount
with the spacer plate (#1), under it with two #10" x
1 1/2" long round head machine screws (#8), flat
washers (#9), lock washers (#10), and nuts (#11).
Slide the plunger switch in the slots of the mount so
the plunger moves "in" about 1/8" when the cam on
the push rod activates it and tighten the screws. Do
not "bottom out" the plunger on the switch or it could
be damaged.
