Thanks Gene,  I figured that must be the deal.  Chains instead of the bull 
gears AC uses for the final drive.  I had no idea Case used them.  It's kind 
of a take copy from the early Mack trucks I guess?

    Charlie;

    Yes, Case has used the chain final drives since the mode L was
introduced in 1929 and up till the early 60's 930.

    The differential was directly behind the transmission with stub, or
brake shafts on each side of the of the differential supported by bearings ,
then the brakes outboard of this. Each shaft had a pinion chain sprocket.
Each rear axle is independent with a driven sprocket on the inboard end. The
large roller chain connects the pinion to the driven gear. This is the final
reduction in the drive system. This system was used on all L,S and D series
as well as the 500, 600, 900 and early 930 tractors.
