Drive belt date codes ?

[cranetruck]

I suspect that these numbers represent date codes for the belts (week and year) and if so, they give a pretty good understanding of the maintenace performed over the years.

For example, the compressor drive belt was changed in 1975. This for a vehicle that was used at the field artillery school (Ft Sill, OK), no less.

Makes one wonder how many PS Magazine articles were actually read or how many TMs were even looked at. More credit must be given to the vehicle designers.....
Come to think of it, most of my manuals and PS magazines are un-smudged except by yours truly.

Can't say for military vehicles, but Musclecar era Mopars had belts stamped with the part #, vendor code and a date code…. For years, NOS belts were worth hundreds and in a few cases, thousands, until good repros came out.

I can tell you, it's fun being a judge and trying to lay on your back with a mirror to try and read the #'s
