That’s a great thing Dave. First quick thought is power window motors with eccentric things on them some how.

The cams hold the shoes at full up or full down via the support rod . Each pic. show in up or down mode .

Oh, now that you say cam I get it. For some reason I was thinking the rod is tightly connected to the cam lobe/ring, but it just rests on it right? :geek:

My John Deere snow thrower does have a sprocket chain idler. My Ford thrower has a plastic chain idler. So do the Case ones need one. Or not. ? Hard to say.


Noel
The newer design uses an adjustable bearing on the shaft sprocket and the auger is fixed in one spot .

Like in the parts diagram .

Dave
My caster is like the one you showed, but by moving the sprocket shaft it only tightens it a little. There are three different positions.

Harry here is the simplest way to do an idler . Spring loaded would be more involved .

That is a standard idler for a #40 chain . It i s about 3" in Dia.

Hopes this helps

Hey Dave- Maybe I missed this but why not use the adjustment mechanism from the newer SB48 snowcasters?

Because I’m new to Case’s, what would that be.

Was thinking the same thing. Then while your at it, use the old auger adjustment system to bring the auger as close to the housing possible and then tighten the chain like the sb48. I've had an older case caster with my 4000 series. I swapped the mule drive around. Then I got my hands on my current sb48 which was correct for my tractor. I like the chain adjuster better then the older auger adjustment. This sb48 was in way better condition.
