General Safety Instructions
1. General Safety Instructions
 Read and observe all Warning and Caution hazard alert
messages. The alerts provide information that can help
prevent serious personal injury, damage to components,
or both.
Failure to follow the instructions and
safety precautions in this manual could
result in improper servicing or operation
leading to component failure which, if
not avoided, could result in death or
serious injury.
 All repair and maintenance should be performed by a
properly trained technician using proper/special tools,
and safe procedures.
NOTE: In the United States, workshop safety requirements
are defined by federal and/or state Occupational
Safety and Health Act (OSHA). Equivalent laws
could exist in other countries. This manual is
written based on the assumption that OSHA or
other applicable employee safety regulations are
followed by the location where work is performed.
NOTE: Before rebuilding the HOLLAND®Fifth Wheel
review the model number on the serial tag. This
rebuild procedure applies only to the FW35TT/
XA-351-TT and FW67/XA-351-UBT elevating fifth
wheel top plates.
IMPORTANT: All maintenance MUST be performed
while the tractor is uncoupled from
the trailer.
IMPORTANT: These instructions apply to the proper
rebuild of FW35TT/XA-351-TT Series and
FW67/XA-351-UBT elevating fifth wheel
top plates only. There are other important
checks, inspections, and procedures not
listed here that are necessary, prudent,
and/or required by law.
 For proper installation procedures, refer to Installation
Manual XL-FW10008BM-en-US available on the internet
at www.safholland.us.
IMPORTANT: Prior to operation of the fifth wheel, verify
that the fifth wheel has been properly
installed on the vehicle.
Failure to properly repair and install the
fifth wheel could adversely affect
performance resulting in tractor trailer
separation which, if not avoided, could
result in death or serious injury.

2. Model Identification
This manual contains the installation procedures for SAF-
HOLLAND rebuild kits RK-351-TT and RK-351-UBT. Prior to
rebuilding, verify the correct rebuild kit by identifying the fifth
wheel model number, which can be found on the fifth wheel
serial tag.
The fifth wheel serial tag is located on the side of the fifth
wheel top plate, above the bracket pin location or near the
pickup ramps (Figure 1). The fifth wheel model number and
serial number are listed on the tag as illustrated (Figure 2).
For FW35TT/XA-351-TT Series fifth wheels (Figure 3), use
the RK-351-TT Rebuild Kit.
For FW67/XA-351-UBT Series fifth wheels (Figure 4), use
the RK-351-UBT Rebuild Kit.

Top Plate Removal
3. Top Plate Removal
IMPORTANT: The FW35TT/XA-351-TT Series fifth wheel
assembly has replaceable pocket inserts
installed between the fifth wheel top
plate and mounting base. When removing
the top plate, the pocket inserts will either
remain inside of the top plate pockets, on
top of the mounting bracket caps, or may
fall out.
Failure to prevent pocket inserts from
falling out of the top plate could cause a
potentially hazardous situation which, if
not avoided, could result in minor or
moderate injury.
1. Remove the clinch pins from the bracket pins on both
sides of the fifth wheel top plate (Figure 5).
2. Using a pry bar, pull the bracket pins out on both sides of
the fifth wheel top plate (Figure 5).
3. Disconnect the air lines from the air cylinder under the
fifth wheel top plate. If the fifth wheel is equipped with
auto-lube, disconnect the grease lines.
4. Using a lifting device capable of lifting 500 lbs. (227 kg),
remove the top plate from the mounting base. Place the
fifth wheel upside down on a flat, clean working area.
NOTE: Follow the instructions published by the lifting
device manufacturer for proper operation of the
lifting device.
5. Completely remove all components from the fifth wheel
and discard.
IMPORTANT: DO NOT reuse old parts that were
removed during disassembly.
Do not hit steel parts with a steel
hammer as parts could break, sending
steel fragments flying in any direction
creating a hazard which, if not avoided,
may result in minor to moderate injury.
6. Thoroughly steam clean the top plate.
7. Inspect the fifth wheel top plate for cracks, damage,
distortion, and loose lock pin holes. Fifth wheels with
cracks, damage, distortion or loose lock pin holes MUST
be replaced.

Failure to replace a cracked, damaged or
distorted top plate could result in
improper fifth wheel operation and
trailer separation which, if not avoided,
could result in death or serious injury.

Rebuild Procedures
Figure 6
Figure 7
4. Yoke Installation
1. Lubricate tips of the yoke with a water-resistant lithium-
based grease (Figure 6).
2. With the fifth wheel top plate upside down and the
threaded hole of the yoke facing up, slide the yoke into
the top plate casting (Figure 6).
3. Lubricate the inside tube of the spring block with a
water-resistant lithium-based grease (Figure 7).
4. Set the spring block into place, ensuring the angled
end of the spring block is facing toward the top face
of the top plate casting (Figure 7). Start two (2)
M12 x 1.75 x 40 mm hex head cap screws to hold the
spring block in position.
5. Install the yoke spring over the spring block tube, as
illustrated in Figure 8.
6. Finish securing the spring block by tightening the hex
head cap screws, alternating back and forth, until each is
torqued to 80 ft-lb. (108 N•m) (Figure 8).
7. Slide the yoke shaft, through the spring block and yoke
spring, into the yoke. Align the recessed hole in the yoke
shaft with the threaded hole in the yoke (Figure 8).

Rebuild Procedures
5. Lock Installation
1. Lubricate the lock pin holes of the lock jaws with Never-
Seez (provided with the kit) (Figure 9).
IMPORTANT: Only use Never-Seez when lubricating the
lock pin holes of lock jaws. DO NOT use a
substitute lubricant.
2. Attach the lock spring onto the lock jaws and force them
closed, extending the lock spring (Figure 9).
3. Slide the closed lock jaws into the top plate casting,
lining up the lock pin holes of the lock jaws with the lock
pin holes in the casting. Be sure to position the lock jaws
with the kingpin guides facing away from the casting
(Figure 9). The yoke will hold the locks closed once they
are in place.
4. With the lock jaws properly positioned in the casting,
drive the lock pins up from underneath the casting,
through the aligned lock pin holes of the casting and
lock jaws until the heads are flush with the casting
(Figure 10).
NOTE: The spring on the lock jaws may pull the lock pin
holes out of alignment when installing the lock
pins. If needed, insert a bracket pin through the
lock pin holes from the top to align the lock pin
holes while installing the lock pin from the bottom.
5. Install the lock pin washers and M27 x 3 lock nuts onto
the lock pins to secure (Figure 10). Torque to 140-160
ft-lb (190 to 217 N•m). Use the hex feature on the end
of the lock pins to hold the lock pin stationary while
torquing the lock nut.
