INSPECTION / OPERATION / MAINTENANCE
The 160HD Coupling is only to be used and
maintained with Premier parts listed in the
Replacement Part Information section. Any
substitution or use of non-Premier parts in a 160HD
Coupling will VOID ALL PRODUCT WARRANTY.
Installation Procedure
:
1. The 160HD Coupling must be installed to
comply with the Federal Motor Carrier Safety
Regulations. Specifically, Section 393.70,
Paragraph C: “Towing of Full Trailers.” Prior
to install or operation, consult with local,
State and Federal agencies, as there may
be additional applicable laws governing
installation and use of this product.
2. Make certain that the cross member the 160HD
Coupling is to be mounted on is of sufficient
strength to withstand the load rating of the
coupling.
3. Using the Standard Installation Drawing,
measure and layout the cross member and
then drill the holes for the mounting bolts.
4. Mount the 160HD Coupling using either Premier’s
159 Bolt Kit and provided torque value, or
four other 9/16” grade-8 bolts and grade-C
locknuts (or grade-C nuts and lock washers).
Only use new fasteners when mounting
couplings or drawbar eyes and torque to SAE
specifications.
5. Once mounted, check the latch components
for proper operation and clearances (see the
Inspection/Operation/Maintenance section for
opening and closing the latch). If the operation
of the latch components is sticky, lubricate
all rotation points with a light penetrating
oil. Work the latch assembly several times
to distribute the lubricant evenly and remove
any excess with a rag. Do not apply lubricant
to the pintle/hook or saddle area of the 160HD
Coupling.
6. An “IMPORTANT WARNINGS!” sticker
was enclosed. This must be attached to the
coupling or cross member and be visible for
the end user to read.
Inspection and Maintenance
:
1. Visually inspect the coupling body and latch
components for cracks, impact damage and/
or deformation before each and every use. Do
NOT use if any of these conditions exist.
2. Check for wear in the saddle area. If the 1
23/32” dimension shown in the 160 Standard
Installation Drawing is worn 1/8” or more, the
coupling is considered out-of-service and must
NOT be used.
3. If the wear area on the pintle/hook has worn
20% or more from its original cross-section,
the coupling is considered out-of-service and
must NOT be used.
4. Check the gap between the top of the pintle/
hook and the adjacent surface of the 152 Latch
before each and every use. If a gap of 3/8” or
more exists between these two surfaces, the
coupling must be taken out of service and is
not to be used.
5. Lubrication of the latch components must
be performed at 90-day intervals or sooner
depending on the operating environment.
Lubricate the latch components with a spray-
type lubricant to evenly coat the 274 Bolt,
153B Roll Pin and 151 Trigger. Squeeze the
trigger and rotate the latch components several
times to evenly distribute the lubricant.
