Good Day All,

Firstly my apologies if this has been covered before but I am seeking some info on the bridge classification disks used on Australian CMP's.

I just need confirmation of the diameter and the thickness, or gauge, of the steel from which they are made.

I read somewhere that they are 6" in diameter but that does not seem to be the case based on the spacing of the bracket holes to hold it and a picture of what I believe to be an original on an F15. Rough proportioning from the photo of the original would put it at 7" to 7-1/2" diameter based on the 5" between centres of the mounting holes.

I also note from AWM photos "5" ton is the amount shown on a F15A disk. That seems high based on weight of vehicle and cargo capacity. Were different weights specified or did all F15A's get a 5 ton limit?

Thanks for any info. May try cutting out one on the lathe this winter if I can confirm the diameter and thickness. Bolted to a block of wood on a faceplate it shouldn't be too hard to do.

Cheers,
