TRACK AND SUSPENSION

General Information (Cont):

Roadwheel support arms although they carry different part numbers are physically

interchangeable. Replace shock provisional arms with similar arms if possible.

Drive sprockets, carriers, roadwheels, track, track adjusters and idler wheels are

identical throughout the M113 FOV.

The track idler arm assemblies used will need modified mounting provisions. When

changing the idler arm assembly the spindle must also be changed. The mounting bolt

holes will align with the rosan inserts in the hull if using the updated suspension system

or if using the old parts depending on the vehicle being repaired. The six mounting bolts

will hold the assembly without major problems.

The opposite side idler arm assembly can be used but only the bottom bolt holes

will align. For last resort use only should an idler be used with only two bolts holding

the spindle assembly.
