THE FIRST NAME IN QUALITY COUPLINGS
BEFORE GETTING STARTED:
► This procedure should only be performed by a
qualified mechanic.
► Tools required: Snap ring pliers, flat-bladed screw
driver, 1/8” allen wrench, 1 1/4” socket, small
hammer.
► CAUTION: When removing and replacing snap rings
the appropriate snap ring plier tools are necessary.
Do not attempt removal or replacement without the
correct snap ring plier tools. In addition, use caution
when removing and replacing snap rings – Do not
over-expand them as damage could result. Also,
when assembling a snap ring into position - Make
certain that the snap ring is fully seated into the
groove.
► Safety glasses are required for all of the following
procedures.
► Prior to disassembly, familiarize yourself with the
location of all the various parts in the coupling. This
will assist in the assembly process.
► See the attached Image Reference Section to
identify the various product parts as well as the noted
positions (i.e. TOP, BOTTOM, FRONT & BASE) of
the coupling body. This will assist in the assembly
process.
DISASSEMBLY
1) As stated above, take a few moments to view the
coupling’s components and their respective positions,
prior to proceeding with disassembly.
2) Place the coupling on a flat work surface, with
mounting base down, pintle hook pointing away from
you with the handles on the right side. Remove the
891P Pin from the 891 Handle.
3) Place the coupling’s latch system in the opened
position by rotating the 896 Handle counterclockwise
until it stops. While holding the 896 Handle in the
maximum rotation position, grasp and rotate the 891
handle counterclockwise to full rotation, then release
896 Handle. The 896 Handle should hold the 891
Handle from rotating back to its previous position.
4) Remove one of the 894Z-1 Snap Rings that secure
the 894 Pin. While holding the 892 Hook, push the
894 Pin out. This will allow for removal of the 892
Hook from the bottom access hole in the coupling.
If the 894 Pin is stuck, use a brass pin or other soft
material to tap it out. Do not strike any components
with steel pins or hammers.
5) Measure the wear area on the pintle horn of the
892 Hook. If the wear is at or exceeds 20% of the
cross section, the coupling is to be considered Out of
Service.
6) Keep clear of the 891 Handle’s rotational space (as
it will release quickly) and rotate the 896 Handle
counterclockwise until the 891 Handle assembly is
released.
7) Prior to further disassembly, position the coupling
(see Image #2, Fig. 2) with the topside facing down
onto work surface and view the latch & spring
components in particular, noting their respective
positions. This will be helpful for proper reassembly.
8) Reposition the coupling with mounting base down
pintle hook if in place would be pointing away from
you, and the handles are on the right side, as
previously described. Remove the 387 Locknut
which secures 891 Handle.
9) Using a brass or other soft material as a punch, tap
on the center of the threaded end of the 891 Handle,
to free it from the tapered seats in the 893 Pawl and
remove it from the coupling body. Note: When the
handle is removed; the 893 Pawl, 893A Spring, and
891C Bushing are also free to be removed.
10) Remove the 275-50 Snap Ring from the end of the
896 Handle.
11) Position coupling body with the topside facing down
onto work surface (see Image #2, Fig.2 bottom view).
Remove the 895C set screw that secures the 895
Latch to the 896 Handle. Grasp 896 Handle and
890R
Coupling

pull sideways, removing it from the body. When the
896 Handle is removed, the 895 Latch and 895A
Spring are also free to be removed. Please note that
Thread Locker is used to secure the 895C Set Screw.
Therefore it may be necessary to slightly heat-up the
part with a torch, in order to remove the set screw.
CAUTION: Do Not apply heat to the 895A Spring or
permanent damage will occur.
12) If the 891P Pin & Cable are damaged, you can
now remove them. Using a chisel or flat-bladed
screwdriver placed at the base of the 16DS Drive
Screw, tap with a hammer to wedge the 16DS up and
out of the hole it resides in, and remove the 891P Pin
& Cable.
13) Disassembly is now complete. Clean and inspect
parts and body for wear and/or damage. If wear
exists or damage is noted, replace affected
part. NEVER ATTEMPT WELD REPAIR OF ANY
DAMAGED OR WORN COMPONENT.
DISASSEMBLY IS COMPLETE
IMPORTANT NOTES TO CLEAN,
INSPECT & LUBRICATE:
► Use only genuine PREMIER replacement parts on
any repairs. Use of other parts, which can have
different specifications or tolerances, may fail to alert
you to non-obvious damage to the hitch which can
lead to hitch failure.
► All body holes, part holes and pins need to be
thoroughly cleaned and lubricated with a heavy
grease before the parts are reassembled. If a bushing
resides in a part, lubricate the hole prior to installing
the bushing. (DO NOT LUBRICATE PINTLE HOOK
WEAR SURFACE).
► Clean, inspect and lubricate latch components
every 90 days or sooner if required by the operating
environment.
► Clean and inspect the coupling for damage and
excessive wear prior to each and every use.
► Do not over-tighten fasteners as this may cause
damage.
ASSEMBLY
1) With the coupling body positioned on its topside as
shown in Image #2, Fig. 2. Slide 896 Handle into
the body from the right side until approx. 1/2” of the
handle is protruding past the inside surface of the
body.
2) Place the 895A Spring inside body onto the
protruding portion of the 896 Handle, to temporarily
hold the 895A Spring in position. Straight spring leg
will be pointing towards you. (See Image #2, Fig. 2
for spring position.)
3) Place 895 Latch into position, making certain that
the spring catch on the spring is located on the long
flat side of the part. While holding the 895 Latch in
position, slide 896 handle thru the 895 Latch and
continue thru the other body sidewall until snap ring
groove is exposed. (See Image #2, Figs. 2 & 4 for
spring and latch position.)
4) Locate counter-drilled hole in 896 Handle and align
it with the tapped hole in 895 Latch. Install 895C Set
Screw into 895 Latch, making certain it maintains
alignment with 896 Handle counter-drilled hole, and
then tighten in position. 895C Set Screw should
be flush with the surface of the 895 Latch. If it is
protruding, it is not aligned with the counter-drilled
hole in the 896 Handle. (See Image #2, Fig. 4 for
approx. handle position when completed.) Use a
permanent thread locker to secure the 895C Set
Screw.
5) Rotate the 896 Handle counterclockwise checking
for spring resistance. If the 895A Spring is installed
correctly, a smooth increasing spring resistance
should be felt when handle is rotated. If no
resistance or binding is felt, the spring and/or part is
not installed correctly and must be corrected prior to
proceeding further.
6) Install 275-50 Snap Ring into groove provided on the
end of the 896 Handle. Install the 894Z-1 Snap Ring
into groove provided on 891 Handle.
7) From the left side of the body, insert the 891C
Bushing into the hole (where the 891 Handle will
reside), with the cut out lugs going inward first. Make
sure the 891C Bushing is flush with the interior body
wall.
8) Place 893A Spring into body (opened spring legs
pointing away from you), and align spring with the
hole that the 891C Bushing is resting in. When
aligned, push 891C Bushing into spring loop just
enough to hold spring in position. (See Image #2,
Figs. 2 & 4 for spring position and orientation.)
9) Grasp 893 Pawl and lower into position, making
certain the closed loop of the spring is closest to you
and catch the backside of the 893 Pawl on the spring
as shown in Image #2, Fig. 4. Align the 893 Pawl

1-800-255-5387 • www.premier-mfg.com
premier manufacturing company Page 3
with the body hole and install 891 Handle from right
side of body, through the spring, pawl, and 891C
Bushing. While holding 893 Pawl, rotate the 891
Handle until handle end points away from you. Then
engage tapered flats on handle with tapered seats
in 893 Pawl and push handle snuggly into 893 Pawl.
Grasp the end of the 891C Bushing and rotate it to
align lugs with the tapered seats in the 893 Pawl
and push inward to seat. (See Image #2, Figs. 2, 3
& 4 for parts position and orientation.) Please Note:
The 893 Pawl can be put in backwards, potentially
causing false latching to occur. Pay particular
attention to Image #2, Fig. 4 for proper orientation
prior to placing into body.
10) Install 387 Locknut onto 891 Handle and tighten.
Make certain that during tightening of the 387
Locknut that the 891 Handle’s tapered seats and the
891C Bushing lugs maintain their proper position in
the 893 Pawl and remain seated during tightening.
11) Verify that 2-3 threads of the 891 Handle are past the
end of the 387 Locknut. This assures the tapered
flats on the 891 Handle and the lugs on the 891C
Bushing are engaged properly with the 893 Pawl.
12) Rotate 896 Handle counterclockwise to full
rotation and hold in position. Rotate 891 Handle
counterclockwise checking for resistance. If spring
is installed correctly, smooth increasing spring
resistance should be felt when handle is rotated.
If no resistance or binding is felt, the spring and/
or parts are not installed correctly and must be
corrected prior to proceeding further.
13) Place coupling on mounting base with shroud
opening facing up. Place latch system in opened
position. (Rotate the 896 Handle counterclockwise
until it stops. While holding the 896 Handle in the
maximum rotated position, grasp and rotate the 891
Handle counterclockwise to full rotation, then release
896 Handle. The 896 Handle should hold the 891
Handle from rotating back to its previous position.)
14) Grasp 892 Hook and insert into body thru large
opening facing towards you (this would be the
bottom of the coupling as mounted on vehicle). Align
hook with hole in body and slide 894 Pin into body
hole and on through the 892 Hook.
15) Install the (2) 894Z-1 Snap Rings onto the ends of
the 894 Pin. Make certain the snap rings are fully
seated into the groove.
16) If the 891P Pin & Cable were damaged and
removed, you can now replace them. Securely
mount the coupling in a vise, as if mounted on a
vehicle. Place 891P Pin & Cable end over hole in
body and insert the 16DS Drive Screw into the hole
and tap into position until fully seated.
17) Test the coupling for proper operation, by opening
and closing it several times. If coupling operates
smoothly and correctly on all attempts, it is ready to
be mounted onto the vehicle and put into service.
18) If the 891P Pin cannot be inserted into 891 Handle
when in the locked position, or the pawl is not fully
seated into the 892 Hook, then remove the hook,
grind a small amount (approx. 1/32” off the end of the
pintle), reinstall and test again.
19) Retest the coupling for proper opening and closing
operation. If coupling operates smoothly and
correctly on all attempts, it is ready to be mounted
onto the vehicle and put into service.
20) Use only new fasteners torqued to SAE
specifications when mounting the assembled
coupling to its mounting structure.
WARNING:
Do NOT bind-up (jackknife) any application, as
stresses can cause damage to the hitch, drawbar
eye, other components or any combination of them.
Jackknifing may result in failure of products or
components, resulting in detachment of the trailer
while in use.
- 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
