Figure 13-36 incudes an exploded parts diagram
of the SR-80 undercarriage for your reference.
2.
Remove the outer plate securing the assemblies to
the shaft. (Most plates will be a two bolt design.
The one bolt version is shown here.) (fig. 13-13)
3.
Loosen and remove the 4 bolts securing the bogie
assemblies together around the mounting shaft.
(fig. 13-14, 13-15)
4.
The inner and or outer bogie wheels may now be
removed with an impact wrench and allen socket
as shown in fig. 13-16. If necessary, clamp one
wheel in a vise to keep the axle from spinning
while you remove the bolts.
Note:
The wheel assemblies in the SR machines use
metal face seals to keep dirt/debris out of the wheel
bearings. During wheel removal/replacement, it is nec-
essary to remove, inspect and clean all components
prior to reassembly to ensure proper function.
5.
Remove both wheels from the hub. (fig. 13-17)
Note:
Take care not to drop the metal face seal halves.
The sealing surfaces are surface ground and have an
extremely fine finish. If scratched or disfigured, the
seal will not function as intended.
Also, take care not to lose the keys for indexing the
wheels onto the shaft.
Note:
Now is a good time to inspect the components
for damage or wear. If the bearings do not roll smooth-
ly when rotated, replace them. If the seals appear worn
or damaged, replace them. If the wheels are worn or
damaged, replace them. If the components appear to
be in good working condition, you may reuse them.
