Installation Guide
Notes:
Installer / owner is responsible for locating rigid mounting
points to attach clevis mounts. A structure may need to be
fabricated to allow the tow bar to be attached to the frame
of the towed vehicle.
It is recommended that clevis mounts
be secured to a flat, nearly vertical area of the bumper.
Clevis mounts should be spaced equally from center line of
vehicle. Recommended clevis mount spacing is 26" to 41",
with 33" preferred.
Step 1
Mark both centers of the clevis mounts (#2)
on the attachment surface at the desired width.
Step 2
Using the clevis mount as a template, drill two 1/2" holes
into the attachment surface, both sides.
Step 3
Secure the clevis mount to the attachment surface with
1/2" - 13 x 1 3/4" hex head cap screws (#8), 1/2" flat washers
(#12) and 1/2" - 13 center lock hex nuts (#11). See Figure 2.
Torque all 1/2" fasteners to 75 ft-lbs.
Step 1
Secure connector weldments (#3) to tow bar arms (#5) with
1/2" - 13 x 3 1/2" hex head cap screws (#7) and 1/2" - 13 top
lock flange hex nuts (#10). Tighten the 1/2" hardware until
contact is made with both sides of the tow bar arms. See
Figure 3. NOTE: Tow bar arms (#5) must swing freely; back
off hardware slightly if necessary.
Step 2
Attach the tow bar assemblies to the previously installed
clevis mounts using 1/2" safety pins (#6).
Step 3
Loosely secure the coupler assembly (#1) to the tow bar
arms (#5) using the bolt plate weldments (#4), 3/8" conical
washers (#13) and 3/8" - 16 center lock hex nuts (#9).
Step 4
Center the coupler assembly with the towed vehicle
and torque the 3/8" fasteners to 31 ft-lbs.
Step 5
Attach the tow bar coupler to the 2" ball of the towing vehicle.
NOTE: Insure that the tow bar coupler is straight and that the
height difference between the ball and the clevis mount does
not exceed 6". Adjust ball height to make the tow bar level.
