II.
Insert a 3/8” - 16 x 1 1/4” swing bolt with the tab
pointing to the rear of the chassis. Secure with a 3/8”
washer and 3/8” - 16 Nyloc
®
nut. Tighten as described
in step 10.
III.
Prepare T-Bolts and stabilizer tubes as described
in step 12, except the inner tube should be set at 1”
instead of 5”.
IV.
After fully retracting rear telescoping jacks, attach
the clevis end of the stabilizer inner tube to the swing
bolt tab on the rear side of the jack using a 3/8” - 16 x 1
1/2” bolt with a 3/8” washer on the top and bottom of the
tab and a 3/8” - 16 Nyloc
®
nut. Tighten nut until tight.
V.
Repeat steps 16A.I-16A.IV for opposite side of
the chassis.
B.
For chassis that are constructed with C-Channel rear
cross-members and uninsulated, go to step 17.
C.
For chassis that are constructed with C-Channel rear
cross-members or tubular frames and/or insulated, refer
to step 18.
17.
Attach a 3/8” - 16 x 1 1/4” swing bolt to the clevis end
of the stabilizer outer tube with a 3/8” - 16 Nyloc
®
nut and
3/8” washer. Tighten nut enough to allow swing bolt to
point upwards.
A.
Rotate stabilizer tube toward center of chassis and up
to cross-member identified in step 2.
B.
Mark where center of swing bolt meets the center of
the cross-member front-to-back on the bottom of the
cross-member.
C.
Align a stiffening pad with the outer hole centered
on the mark for the center of the swing bolt. Clamp the
stiffening pad to the cross-member with a pair of locking
pliers and drill mounting holes with a 3/8” bit.
D.
Secure stiffening pad to the cross-member with a 3/8”
- 16 x 1 1/4” bolt, 3/8” - 16 Nyloc
®
nut and 3/8” washer in
the inside mounting hole.
E.
After removing the locking pliers, attach swing bolt
to remaining mounting hole with a 3/8” - 16 Nyloc
®
nut
and washer.
F.
Repeat steps 17A-17E for opposite side of the chassis.
18.
Prepare spacer mounts as described in step 8. Rotate
stabilizer tubes toward center of chassis and upward to
cross-member identified in step 2.
A.
Using the spacer mount as a template, mark the
mounting holes by aligning one short edge with the center
of the cross-member. Make sure the spacer mount is
parallel to the edge of the rear cross-member.
B.
Center punch and drill 1/8” pilot holes at each mounting
hole location.
C.
Drill 1/8” pilot holes at the four mounting hole locations,
then re-drill the holes located closest to the electric jacks
to 5/16” on both sides of chassis.
D.
Tap the 5/16” holes with either a 3/8” - 16 tap or a 3/8” -
16 x 1” self-tapping bolt. Lubricate tap as needed.
E.
Secure spacer mount to bottom of rear cross-member
with a 3/8” - 16 x 1” self-tapping bolt, taking care to keep
the remaining pilot hole centered in the mounting of the
spacer mount. Tighten bolt securely.
F.
Re-drill the remaining pilot hole to 5/16”. Then insert a
3/8” - 16 x 1” self-tapping bolt and tighten.
G.
Repeat steps 18A-18F for opposite side of chassis.
19.
Place Warning Label in any available location that is
visible while operating electric leveling jack switch.
A.
Clean mounting surface thoroughly.
B.
Remove backing from label and adhere to mounting
surface using a squeegee or similar tool.
