Mounting Information
Mounting Information
Mounting Height
When mounting a coupling device, a height should be selected
that results in the chassis of the towed vehicle being close to
level with the ground. An offset in mounting height will create
vertical and horizontal displacement of the drawbar in relation
to the mating component of the coupling device. This mismatch
in height will lead to accelerated wear and changes in vehicle
handling.
Improper Mounting Height
(causing excessive vertical and horizontal movement)
Mounting Surface
The mounting surface for a coupling device must be flat and of
adequate strength to support the rated capacity of the coupling
device. It must have sufficient vertical load and horizontal load
capability to comply with the requirements of SAE J847.
Mounting Hardware
All mounting hardware must be new ASTM Grade 8 bolts with
hardened steel washers and ASTM Grade C locknuts. Bolts
should be of sufficient length to provide a minimum of two (2)
full threads beyond the end of the nut under recommended
torque.
Proper Fastener Selection
Bolt head designation
for Grade 8 is 6 equally
spaced bars as show.
A minimum of 2 full
threads must be exposed
after proper torquing.
To develop the full rated capacity of a coupling device, all
required mounting fasteners must be present with proper
and equal torque applied to each fastener. Torque values and
procedures should follow SAE J429 and are stated in the Owner’s
Manual shipped with each Holland coupling product. This
information is also available online at the SAF-HOLLAND website.
