Whatever your application, selecting the proper equipment for the job is very important� Proper selection along
with regular inspection and maintenance will help keep operating costs minimal while providing long life to each
component� Below are general guidelines for selecting Premier Couplings and Drawbar Eyes� If you feel that your
application is unique, please give Premier a call so that we may help you through the selection process�
Follow these four steps to ensure proper selection of Premier Couplings and Drawbar Eyes�

Product Catalog
(Based on Steps 1 - 3)
Step 1:
Determine “Gross
Trailer(s) Weight”
(GVWR(s) of towed trailers)
“Gross Trailer(s) Weight” is usually determined by the Gross Vehicle Weight Rating (GVWR)� This information is
attached to the trailer by the trailer manufacturer�
For “Double Trailer” configurations, only the rear trailer is considered
when selecting your Premier Coupling or Drawbar Eye� In this example, a
Coupling and Drawbar Eye with a “Gross Trailer Weight” rating of 40,000 lbs�
(18,143 kg) would be the minimum rating acceptable for normal, over-the-
road applications (see Tongue Weight section below)�
For “Triple Trailers”, only the two most rearward trailers are
considered in selecting your Premier Coupling or Drawbar Eye�
In this example, a Coupling and Drawbar Eye with a “Gross
Trailer Weight” rating of 80,000 lbs� (36,287 kg) would be the
minimum acceptable for normal, over-the-road applications
(see Tongue Weight section below)�

40,000 LBS 40,000 LBS
40,000 LBS
Environments such as rough uneven roads or off-road use can dramatically increase shock loads to both drawbar
eyes and couplings� In general, increasing the “Gross Trailer Weight” (Step 1:) and “Tongue Weight Capacity”
(Step 2:) by a minimum of 25% will be sufficient for many applications� Even if an application is used off-road
occasionally, the minimum increase necessary for Gross Trailer and Tongue Weight is 25%� Certain types of
equipment and/or operating practices can also dramatically increase loads through equipment binding and/or
improper loading practices� Of special concern is high tongue weight� However, each application is unique and
every environment different, therefore your application may require more than 25%�
Once both “Gross Trailers(s) Weight” (Step 1:) and “Tongue Weight Capacity” (Step 2:) have been determined,
evaluate your operating conditions and apply an appropriate margin of safety�
Browse the Premier Product Catalog and refer to the “Specifications” section of each product� Be sure to review
the “Understanding Premier Load Specifications” section and “Coupling to Drawbar Eye Cross-Reference” sheet
on the next couple pages�
“Tongue Weight Capacity” is the maximum expected weight at
the drawbar eye� If a hinged drawbar is used, the maximum weight
will be approximately 1/2 the overall drawbar weight� If a non-hinged
drawbar is used and the actual tongue weight is not known, you can
approximate the weight by multiplying the GVWR of the towed trailer
by 15%� However, each application is unique and the best practice is
to weigh the tongue when the trailer is loaded to its GVWR�

Model 240KSA Coupling
INSTALLATION
NOTE: DO NOT USE SWIVEL-TYPE
DRAWBAR EYES WITH THE 240KSA
COUPLING.
The 240KSA 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
240KSA Coupling will VOID ALL PRODUCT
WARRANTY.
Installation Procedure:
1. The 240KSA 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
240KSA 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. Note: Center hole for the
240KSA shaft is to be drilled to Ø2 1/8 in.
(54mm).
4. Mount both 235P Mounting Plates using two
3/4” grade-8 bolts and grade-C locknuts,
leaving each bolt slightly loose. Make certain
the bolts are installed as shown in the
Standard Installation Drawing, so the locknuts
are on the back side of the mounting structure.
5. Generously lubricate both faces of both 237NT
Bushings. The 240K Coupling is already
mounted to the 235K Swivel Adapter at the
factory.
6. Slide one 237NT Bushing onto the shaft of the
235K and, using extreme care not to damage
the threads on the shaft, insert the shaft
through both 235P Mounting Plates. Slide the
other 237NT Bushing over the shaft.
7. Clean and lubricate all visible threads on the
shaft.
8. Slide the 238 Washer and thread the 416
Locknut on the shaft. Tighten the locknut until
all slack between the 235K Adapter and the
235P Mounting Plates has been removed.
9. Tighten the 416 Locknut until the desired
rotational stiffness of the coupling assembly
is acquired. Install the 208 Snap Ring into the
groove at the end of the shaft.
WARNING: Do NOT rotate the coupling body
to tighten the nut.
10. Tighten each 3/4” bolt and mating locknut.
Only use new fasteners when mounting
couplings or drawbar eyes and torque to SAE
specifications.
Optional Accessories:
- Wear Gage 14011 (2 in.): To determine hook wear limits.
- Latch Gage 14026: To determine latch gap limit.

INSPECTION / MAINTENANCE / OPERATION
11. Grease both 235P Mounting Plates at the zerk
fittings. Each mounting plate should take a
minimum of 3-4 pumps using a mechanical
grease gun.
12. 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 240K Coupling.
13. 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.
Operation:
OPENING Coupling Latch:
1. While facing the mounted 240KSA Coupling,
push the 133 Latch Lock toward the mounting
plate (away from you) until full rotational travel
is reached. While holding the latch lock in this
position, grasp the top of the 132 Latch and pull
out toward the pintle, rotating the latch until full
rotational travel is reached.
2. Holding the 132 Latch in place, slowly release
the 133 Latch Lock until it has rotated into the
latch.
3. Release the 132 Latch and the 240K Coupling
is now open and ready to couple or uncouple.
Inspection and Maintenance:
1. Visually inspect the 235K Swivel Adapter, 235P
Mounting Plates, 240K 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 the gap between the 132 Latch and the
top of the pintle/hook on the coupling body
before each and every use. A gap of 3/8” or
more means the coupling must be taken out-of-
service and repaired or replaced.
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. 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 all rotation points.
Rotate each latch component several times to
evenly distribute the lubricant. Lubricate the
mounting plates at the grease zerks using a
mechanical grease gun.
5. Remove any excess lubricant with a rag. Do not
apply lubricant to the pintle/hook or saddle area
of the coupling.
6. Check for wear on both 237NT Bushings. Any
slack should be removed by tightening the 416
Locknut. Excessively worn 237NT Bushings
should be replaced immediately.
7. Never weld on any Premier part in order to
repair damaged or worn areas. Field and/or
shop welds are inadequate and may further
weaken the coupling.
8. WARNING: Other inspection and maintenance
procedures are also required prior to the
operation of combination vehicles. Consult
and follow all Federal Motor Carrier Safety
Regulations as well as local, state and federal
guidelines.

Operation:
CLOSING Coupling Latch:
4. Rotate the top of the 132 Latch toward the
pintle until full rotational travel is reached. Push
the 133 Latch Lock toward the mounting plate
as far as it will go.
5. While holding the 133 Latch Lock in this
position, slowly release the 132 Latch. Release
the latch lock making sure it seats fully down
in the slot on top of the latch. The 240KSA
Coupling latch is now closed.
6. To test for proper latching, apply a force toward
the coupling body to the front of the 132 Latch
(down near the top of the pintle). THE LATCH
SHOULD NOT OPEN! If the latch does
not stay closed, do not use until it has been
repaired or replaced.
7. This product is designed to be operated within
its free rotation limits. It is the responsibility of
the vehicle designer/end user to ensure that
these limits are not exceeded (do not bind-up/
jackknife).
8. WARNING: Prior to towing, make certain that
adequately rated safety chains have been
properly connected.
- Do not weld on any coupling assembly
- Always use Grade-8 fasteners properly torqued
- Do not apply lubricants to the coupling hook
- Clean & inspect coupling for damage & excessive wear prior to each and
every use
- Lubricate all coupling components at a minimum of 90 day intervals
- Do not bind-up (Jackknife) any application as stresses can cause damage
to products or components, resulting in failure and detachment of the trailer
while in use
