Cat 30 fan help

No adjustment that I can recall -
Fan is gear driven bearings in the timing gear case.
It has been well over 50 years since I was in the fan assembly.
While you have the fan assembly open, be sure to check the friction plates, the fan sometimes slips from wearing these plates, they are held tight by a spring if memory serves.
Check that before you pull the rest of it apart.

I have seen many radiators damaged by the fans!

I had a RD 6 that rubber spacer or maybe the rubber is to help limit shock loading, anyway rubber fell apart, and fan hit the core make a big mess of it. Your 30 is about the same vintage. So maybe what is going on with yours.

In reading this thread I believe I found out what that hand full of wired together rubber pre-drilled (gaskets?) are. In other words I might have just what you need. I will try to find them today. Would they be the same size as a Diesel 40? I have a 40 here to compare it to.

I was thinking it would be a bearing failure but everything looks as it should so far not seeing anything that would have caused it to hit the radiator 

Cody,
As I suggested, check that fiber washer/friction disc just behind the fan blades.
The fan slips over time and wears that away, changes the clearances.

Try to find a schematic of the fan assembly/parts book, etc.
