Hi, skipjack herring.

If you take that sketch and those part #s to a good bearing supplies mob, they should be able to cross reference it all and tell you what if any of it is available.

Failing that, you might be looking at finding a good used set. This 'fella' might be able to help:

Just my 0.02.

You have a wonderful day. Best wishes. Deas Plant.

6B8150 was replaced by 6D0749 which Cat shows a price of about $600 but says contact dealer for availability, so may not be available. Check eBay there is a listing for two 6D0749 new Cat $250 ea. Or Machinerytrader.com shows a few sources

Hi Brian, I wanted to see if the ebay listing gave dimensions but when I searched for 6D0549, it lists a spring for $25? How did you run your search?

Neil I posted wrong number it is 6D0749, which I corrected in original post. No dimensions, but a clear picture and a cat box. Has part numbers but no obvious manufactures name.

I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
