Cent. spares vs Aussie ingenuity

[Mike Cecil]

It is a roadwheel from any of the M113A1 FOV.

There were three types:
(1) Thin Al. with wear plate riveted to inner face
(2) Thick Al.with wear plate riveted to inner face
(3) all steel, (wear plate not required so no rivets.)

(1) and (2) could be mixed on the same axle (there are two per axle, mounted one inwards, one outwards), but not (3) with either (1) or (2).

Roadwheels had to be gauged for thickness to ascertain if they were within tolerance. Too thin = replace.

This is likely (1). The ski tow using these wheels is most likely to have been built after 1965.

(The latest book on the Aust M113A1 FOV states there were two types of roadwheel: steel and Al. As can be seen from the above, this is not correct.)
