Fan Sizes

[jlandry@domain.elided (John A. Landry)]

OK Tommy my boy...

This time I used the calipers (which is what I should have done in the first
place) to measure the difference between the two type of radiator fans.  So
this should be real close.

Radiator fan for fan clutch with threaded coupler:

2-5/8" ID hole in fan
2-1/4" hole spacing to bolt fan to clutch.

Radiator fan for fan clutch with bolt flange coupler:

2-1/2" ID hole in fan
2-1/8" hole spacing to bolt fan to clutch.

Regards,

John L.
