1.0 GENERAL RAILGEAR INFORMATION
SAFETY PRECAUTIONS
If any problems are encountered, please call G&B Specialties, Inc. for technical
assistance.
 Failure to heed to any of the following warnings could result in severe bodily
injury and/or equipment damage.
 Read and understand all manuals completely before attempting operation of
the railgear equipped vehicle or service or installation of the railgear.
 Generic instructions provided below only address RAFNA railgear equipment.
Applicable railway company procedures and policies must be adhered to.
 Ensure that the position and function of all railgear controls are known before
attempting operation.
 Railway company rules governing rail travel must be observed at all times.
 Rail travel speed should always be in conformance with railway company
regulations and should be reduced during inclement weather, passing through
road crossings, switches, frogs, bridges, and curves. Curves of greater than 20
degrees should be negotiated with extreme caution. Operation of this vehicle
at unsafe speeds could result in derailment.
 Ensure the railgear is locked in road or rail position before starting road or rail
travel respectively.
 This vehicle will not operate crossing signals. At level crossings, ensure that no
other vehicles are approaching and flag the crossing to ensure safety. Use
caution when approaching and traversing level crossings.
 Never operate the vehicle if the Gross Vehicle Weight Rating (GVWR), Gross
Axle Weight Rating Front or Rear (GAWR), or the wheel or tire load ratings are
exceeded.
 Before performing any work under the vehicle or railgear, ensure the engine is
turned off and the parking brake is set.
 Ensure all body parts and loose clothing are clear of any moving parts of the
equipment.
 If misalignment of the railgear equipment is indicated, promptly perform the
alignment procedure. Note that excessively worn rail wheels, vehicle pulling to
one side while on rail, and vibration through the vehicle while on rail are
indicators of railgear misalignment.

 Following the first 100 km (62 miles) of combined road and rail travel, the
vehicle road wheel and spacer lug nuts should be re-torqued as per the Road
Wheels and Tires Kit Operation, Service, and Parts manual if applicable.
 On newly installed railgear, following the first eight (8) hours of rail travel,
inspect the rail wheel bearing end-play as per the Railgear Kit Operation,
Service, and Parts manual. During this time, the bearings will have seated and
may require adjustment of end-play. If the end-play is not in accordance with
specifications, bearing failure could occur and would not be covered under
warranty. Also check for sufficient grease in the wheel bearings.
 If the vehicle was derailed or involved in an accident, a thorough inspection of
the complete railgear package for damaged parts should be carried out before
the vehicle is put back in service.

GENERAL RAILGEAR INFORMATION
The RAFNA railgear is a hydraulically operated road-to-rail conversion system. The front and
rear railgear are mounted to the vehicle frame and hydraulically raise and lowered via a 12
VDC electric hydraulic pump or an alternative hydraulic pump (e.g. PTO driven pump). During
road travel, the front and rear railgear are mechanically locked in the road position. During
rail travel, the front and rear railgear are locked in rail position via hydraulic check valves or
mechanical locks, depending on model. A steering wheel lock keeps the vehicle front wheels
straight during rail travel. The railgear’s spring suspension system ensures constant rail wheel
to rail contact and a comfortable ride. Propulsion and braking on rail is provided by the
vehicle original systems through the vehicle’s wheels contact with the rail. Additional on rail
braking may be provided by an optional rail wheel brake package.
The RAFNA railgear is supplied with a group of Operation, Service, and Part Manuals and
Installation Manuals which are specific to the railgear, mounting, hydraulic, wheel, steering
wheel lock, and/or other or optional kits ordered. As a group, the manuals provide all the
information relative to the particular railgear package. The group of manuals may not be
interchangeable with other railgear equipped vehicles due to different options and/or
applications. If replacement manuals need to be ordered, the railgear serial number and/or
the kit numbers must be provided to G&B Specialties.
All the manuals should be read in their entirety before any installation or operation is
attempted. This will ensure that all the information is covered.
All manuals use the “Driver’s Seat” orientation convention. All directions, i.e. right, left,
front and back, are from sitting in the driver’s seat of the vehicle.
The railgear serial numbers, model numbers, and dates of manufacture for both the front and
rear railgear should be recorded below for future reference. This information is stamped on
the railgear identification plate riveted to each railgear.

on Railgear.
IMPACT:
Excessive wear in this area can lead to an axle failure.
ACTION:
Inspect this area as follows to determine the amount of wear acceptable before axle change
is required:
Primary method of Inspection
Inspect vehicle as close to actual use by means of, rail, alignment rack, two by fours or steel
tubing.
Deploy railgear and observe or measure axle movement at the Axle Guide Pin Location.
You can have 1/8” of wear in both the up and down direction from center line of the Axle
Guide Pin.
This would be a total of 1/8” up from center and 1/8” down from center, for a total of ¼”
wear.
If the ¼” wear is all up from center or all down from center, then this would not be
acceptable. If axle is out of specifications replace with Axle R-2930.
Pin should show no wear. If pin shows wear replace with P/N, R990KIT-353.
Alternate method for inspection
Lower Railgear until it is resting on the ground without any load being applied to it. Remove
5/32” cotter pin and slide bellows out of the way, then remove Guide Tube Pin. Now inspect
axle and pin for wear. Replace pin and cotter pin and proceed to other end of axle and
repeat inspection process. Inspection process for pin wear and axle wear is as follows:
If pin shows wear replace with P/N, R990KIT-353.
Use Alternate Method of Inspection drawing which shows limits of wear for slots and holes.
Use appropriate measuring tools to perform the required measurement. Measuring tools will
vary from location to location. If Axle is out of specifications replace with Axle R-2930.
