LIGNMENT
The Rafna railgear must be correctly aligned in order to perform properly, safely, and
avoid excessive wear. All four rail wheels can be independently aligned while lateral
adjustment of the front and rear railgear is accomplished through adjusting the railgear on
the mounting plates. A parallel line system and the following procedure should be used
to perform the railgear alignment. Rafna Industries can also supply a special alignment
tool kit (order part number R-066K) for steel rail wheels only, with which separate
instructions are supplied.
WARNING:
 The vehicle should have had a four-wheel alignment following the
installation of the railgear but prior to performing the railgear alignment.
 This procedure should be done with the vehicle parked on a straight and
level section of rail with the front tires pointing straight ahead in order to
achieve correct alignment.
 Before any maintenance or adjustments are performed under the vehicle
or railgear, ensure the engine is turned off and the parking brake is set.
1.
Fabricate a parallel string line system. Rafna Industries suggests the following (refer
to figure 3-5):
a) Fabricate two metal alignment bars (Item 1) with ½” diameter posts (Item 2) on
each end 18” tall and about 10’ apart.
b) The alignment bars may also have support legs (Item 3) to sit on the rail head.
c) Create a series of circumferencial grooves in each post at 1” intervals to hold the
string lines.
d) Ensure that the two alignment bars are fabricated identical to within 1/32”.
2.
Ensure the vehicle has had a four-wheel alignment following the installation of the
railgear but prior to performing the railgear alignment.
3.
Lower the front and rear railgear to the rail position on a straight and level section of
rail.
4.
Ensure the vehicle front tires are pointing straight ahead and engage the steering lock.
