What is the thread size/pitch of the clutch-fan stud ??

Thanks.

I have a spare water pump at home. I can get it out and measure it for you later if no one else can say.

Try a 3/8-16 bolt.

looks like 1 1/4" 16 tpi to me.

Thanks so much and right you are.


I happened to remember I had one hanging on the hoist, minus the fan.

1-1/4 X 16 UN-2B LH


The reason I asked was that I thought I may have found a source for direct-drive fan-hubs that eliminated the clutch.

The hubs I found are M30 X 1.5 LH and these DO FIT the B-series Cummins.

I had sorta hoped they would fit the I-H as well, but no go.


Well, I tried.
