INSTALLATION OF REAR RAILGEAR KIT
1. To install the railgear at the correct height, ensure that the vehicle is resting on its six
properly inflated tires. Remove tail lights.
2. Position and support the railgear so that the railgear mounting boxes are on either side of
the rear of the vehicle frame with the blind end of the hydraulic cylinders facing the rear
of the vehicle. The mounting boxes should be flush with the rear and top surface of the
vehicle frame (as a starting point) and fit around the vehicle’s suspension hangers. The
holes in the mounting boxes should align with existing holes in the rear of the vehicle
frame. It may be necessary to loosen or remove the fasteners that support the railgear
axle lock system to be able to fit the railgear on the frame. Once the railgear is on the
frame, tighten and torque the 1/2” fasteners securing the railgear lock system to the
railgear to 100 ft-lbs dry. Do not over torque.
3. Ensure that there is approximately 21.5” between the railgear-to-mounting box interface
and the ground as shown in Figure 1. The slots in the mounting boxes will allow for
approx. 1/4” of vertical adjustment, either up or down. If the 21.5” mounting height
cannot be achieved, the vehicle suspension will need to be modified. This modification is
not included with the RAFNA railgear.
4. Fasten each railgear mounting box to the vehicle frame using two 5/8” x 2” long bolts,
four 5/8” washers and two 5/8” nuts through the existing frame holes at the rear as
shown.
5. Repeat step four for two 7/16” x 1 3/4” long bolts, washer and nuts through the existing
frame holes as shown.
6. Using the front-most bottom holes in each railgear mounting box as a guide, drill a 25/32”
hole through the vehicle frame.
7. Fasten each railgear mounting box to the vehicle frame using through the drilled hole
using 3/4” supplied hardware as shown.
8. Using the center hole in each railgear mounting box as a guide, repeat steps 6 and 7.
9. Fasten each rear support bracket to each railgear mounting box using two 1/2” x 1.75”
long bolts, four 1/2” washers and two 1/2” nuts. Slide support bracket up until the top of
the bracket is resting on the bottom of the truck frame. Torque the 1/2” fasteners to 100
ft-lbs dry. Do not over torque.
10. Torque the 5/8” fasteners to 150 ft-lbs dry and the 3/4” fasteners to 175 ft-lbs dry. Do
not over torque.
11. Place the rail wheels below the mounting tables on the railgear axle. Place the rail
sweeps to the rear of the rail wheels and on top of the mounting tables. Fasten the rail
wheels and rail sweeps to the mounting tables with eight 1/2” x 2.25” long bolts, sixteen
1/2” washers and eight 1/2” nuts.

RAIL WHEEL BEARING ADJUSTMENT
The rail wheel bearings require periodic adjustment in order to keep the end-play within
specification. If the rail wheel bearings are not correctly adjusted, failure may occur that will
not be covered under the railgear warranty. Check and adjust the bearing end-play with the
railgear in the road position and with the rail wheels free to turn.
Use a magnetic base dial gauge to measure the end-play of each rail wheel bearing. The
bearing end-play must be between 0.001” and 0.005”. If this is not the case, adjust as
follows:
1. Remove the rail wheel hubcap and gasket by removing the three 1/4” bolts and 1/4” lock
washers.
2. Remove the spindle nut cotter pin.
3. Ensure that the wheel bearing cavity is full of grease.
4. While rotating the rail wheel forward, torque the spindle nut to 20 ft-lbs. Then loosen the
spindle nut and re-torque it to 6 ft-lbs. Re-check and re-adjust the bearing end-play if
required. If no torque wrench is available, tighten the spindle nut until the rail wheel is
difficult to turn by hand. Then loosen the spindle nut and retighten it just until no
looseness can be felt in the bearings. Re-adjust the bearing end-play with a torque wrench
as soon as possible.
5. Install a new 3/16” x 2” long cotter pin through the spindle nut. Tighten the spindle nut
slightly if needed to insert the cotter pin.
6. Re-install the hubcap and gasket using the 1/4” bolts and new 1/4” lock washers. Blue
Loctite can be used on the bolts as an added safety measure. Tighten and torque the 1/4”
fasteners to 12 ft-lbs dry. Do not over torque.
RAIL SWEEP ADJUSTMENT
The distance between the rail sweep rubber and the rail is adjustable and should be
maintained at approximately 1/8”. To adjust the rail sweep rubber, with the railgear in the
rail position, loosen the two ¼” fasteners which secure the rail sweep rubber to the rail
sweep bracket. Slide the rail sweep rubber up or down for the correct clearance. Tighten and
torque the ¼” fasteners to 12 ft-lbs dry. Do not over torque.

RAIL WHEEL LOAD ADJUSTMENT
During rail travel, the railgear removes a predetermined portion of the vehicle’s load from
the vehicle’s wheels and carries it on the rail wheels. A minimum amount of load must be
maintained on the rail wheels in order to avoid derailment. Likewise, a minimum amount of
load must be maintained on the vehicle wheels in order to provide traction for acceleration
and braking.
The rail wheel load should be adjusted following the installation of the railgear once the
vehicle has had all of its permanent load (service body, crane, welders, etc.) installed. The
rail wheel load requires periodic checks; however, it should only require re-adjustment if the
railgear is moved, the vehicle equipment is changed, or the vehicle suspension settles or is
changed. As non-permanent load is added to and/or removed from the vehicle, the rail wheel
load will change also. This is acceptable as long as the weight ratings of the vehicle, axles,
wheels, tires and railgear are not exceeded and as long as the minimum rail wheel load is
maintained.
The rail wheel load must be a minimum of 800 lbs and is checked as described below using a
hydraulic bottle jack equipped with a gauge. If the gauge on the hydraulic bottle jack reads in
pounds per square inch (psi), use Table 4 along with the jack bore diameter to convert this
reading to pounds (lbs). If the gauge reads in pounds, then no conversion is required.
Check each rail wheel load as follows:
1. Place the vehicle on a straight and level section of rail with the railgear lowered to the
rail position. Ensure the railgear is taking load through the tread of the rail wheel and not
on the flange of the rail wheel. The vehicle should only be carrying the permanently
attached load (service body, crane, etc) and any always carried non-attached load
(welders, etc.) during this procedure. Do not include the operator or passengers. Ensure
the vehicle tires have been inflated to the manufacturer’s recommended air pressure and
that they are not in contact with any obstructions except the rails.
2. Place the hydraulic bottle jack on a solid surface beneath the rail wheel spindle housing
and jack the rail wheel off the rail.
3. Insert a piece of paper between the rail and the rail wheel. Lower the jack until the rail
wheel squeezes the paper so that it cannot be pulled out.
4. Slowly jack up the rail wheel while pulling on the paper and observe the jack gauge. When
the paper can be pulled out, stop jacking.
5. Record the load or pressure reading on the jack gauge.
6. If necessary, convert the pressure reading to a load reading using the supplied table.

Adjust each rail wheel load as follows:
There are two rubber springs on the railgear located between each railgear outer tube
assembly and spring plate. Each spring is held in place by a nylock nut above it and a spring
plate with a jam nut below it. The spring plate can be lowered and raised on the threaded
rod to correspondingly decrease and increase the rail wheel load.
1. Raise the railgear until the rail wheels are off the rails.
2. Loosen the 1” nylock nut above each spring and the 1” jam nut under each spring plate.
3. To decrease the load on the rail wheels, lower the spring plates on the threaded rods. To
increase the load on the rail wheels, raise the spring plates on the threaded rods. Each
side should be adjusted the same amount.
4. Lower the railgear to the rail position and re-check the rail wheel loads. Re-adjust the rail
wheel loads if necessary.
5. Raise the railgear until the rail wheels are off the rails. Tighten the 1” jam nut on the
threaded rod so that they are tight against the spring plate.
6. Tighten the 1” nylock nuts above the springs so that the rubber springs are compressed to
3.75”.
7. Following the rail wheel load adjustment, the railgear may contact the vehicle if not
enough clearance was left during installation. Check the railgear clearance to all vehicle
components throughout the full range of railgear and railgear suspension movement. If
there is interference with the vehicle exhaust system, it can be bent to fit, ensuring any
exhaust system modifications conform to applicable laws and regulations. If there is
interference with any other vehicle components, please call G&B Specialties, Inc. for
technical assistance.

RAILGEAR ALIGNMENT
The railgear must be correctly aligned to perform properly, safely, and avoid excessive wear
and derailment. The rail wheels can be independently aligned for toe-in/toe-out and the
railgear can be adjusted side to side (laterally) on the vehicle. A parallel line system and the
following procedure should be used to perform the railgear alignment.
The rail wheel loads should be checked and adjusted, the vehicle should have had a four-
wheel alignment (with the complete railgear package installed on the vehicle and any
suspension modifications done) and the tires should be properly inflated prior to performing
the railgear alignment.
The railgear alignment is done with the vehicle on a straight and level section of rail with the
railgear in the rail position and the vehicle wheels pointing straight ahead. The individual rail
wheel alignment should be done first, followed by the lateral alignment of the railgear.
Each rail wheel is aligned by loosening the four 1/2” fasteners that secure it to the railgear
axle. The rail wheel is then turned into alignment. The four 1/2” fasteners should then be
tightened and torqued to 100 ft-lbs dry. Do not over torque.
The railgear is aligned laterally by loosening the eight 5/8” fasteners that secure it to the
railgear mounting boxes. The railgear is then moved sideways into alignment. It may be
necessary to raise the railgear off the rails to move the railgear side to side. Do not use any
force against the railgear guide tubes as this may damage them and restrict suspension
movement. The eight 5/8” fasteners should then be tightened and torqued to 150 ft-lbs dry.
Do not over torque.
Refer to Figure 5 for alignment measurement and specifications. Use an 18” magnetic straight
edge on the back of each rail wheel to measure from.
Following the railgear alignment, the railgear may contact the vehicle if not enough
clearance was left during installation. Check the railgear clearance to all vehicle components
throughout the full range of railgear and railgear suspension movement. If there is
interference with the vehicle bumper, it can be trimmed and reinforced as required. If there
is interference with the vehicle exhaust system, it can be bent to fit, ensuring any exhaust
system modifications conform to applicable laws and regulations. If there is interference with
any other vehicle components, please call G&B Specialties, Inc. for technical assistance.

RAILGEAR LOCK SYSTEM ADJUSTMENT PROCEDURE
The rear railgear lock system provides a mechanical locking mechanism to hold the railgear
axle in the road position. For the system to function properly, the contact surface of the
angle plate on the axle and the top surface of the locking pins must have a contact length of
approximately 3/4” to 7/8” as shown. If this criteria is not met, the following procedure can
be followed:
1. Raise the railgear so that the lock angle on the rear axle is parallel to the ground. Support
the railgear axle and the lock-up system. *The railgear may not be fully retracted. The
railgear should rotate up past parallel for the lock-up to work properly*
2. Remove lock-up cover (if equipped).
3. Loosen the four 1/2” fasteners that secure the lock-up support to the lock-up frame.
4. Adjust the lock-up support and/or rear railgear up or down accordingly so that the pin and
the contact surface of the angle plate are parallel. Tighten but do not torque the four
1/2” fasteners.
5. Remove the four inside 3/8” fasteners that secure the lock-up plate to the lock-up
support.
6. Loosen the two outside 3/8” fasteners that secure the lock-up plate to the lock-up
support.
7. Adjust the lock-up plate in or out accordingly so that the contact surface of the angle
plate and the top surface of the lock pins have a contact length of approximately 3/4” to
7/8”.
8. The holes in the lock-up plate and the lock-up support allow for horizontal adjustment in
1/8” increments. Align the closest set of holes that will allow a contact length of
approximately 3/4” to 7/8”.
9. Re-install the four inside 3/8” fasteners that secure the lock-up plate to the lock-up
support, that were removed in step #5 above. Tighten but do not torque at this time.
10. Retract the lock pins and lower the railgear. Raise the railgear and ensure that the lock
system has been properly adjusted and functioning properly and that there are no
interferences between lock-up and railgear axle.
11. Repeat the above steps as necessary.
12. Tighten two outside 3/8” fasteners that secure the lock-up plate to the lock-up support.
13. Torque the 3/8” fasteners to 40 ft-lbs dry. Do not over torque.
