Big Radiator Fan "HUB"

[Pete]

Jim, mine has the AX73's. When I had my fan clutch/radiator problem, prevost tried to put the AX74's on and could not get the clutch/a/c platform adjusted far enough away from the radiator to avoid possible contact. Thus the AX74's were installed.

Pete,

I have heard you mention concerning losing the three belts that drive the gearbox and the result was your radiator fan extended damaging your radiator. Sounds painful.

I checked my bracket and a piece of the metal bracket holding the small air bag that controls the belt tension will prevent this over extension of the fan. If you unit does not have this bracket design, perhaps an upgraded bracket would prevent future mishaps.

I'm sorry, thus the AX73's were installed. Sorry bout that

Hector, mine does have the bracket, and we modified that with a piece of rubber hose over the ear of the bracket to keep it from moving to far toward the radiator.
The next time we see each other, I can show you what we did. My radiator has an "X" brace from the upper left corner to the bottom right corner and the upper right corner to the bottom left corner. This "X" brace is about 1/4" in diameter and on the inside of the radiator nearest the fan. The damage was done when the assembly hit the "X" brace shearing off the fins on the round aluminum portion causing them to penetrate the radiator. Guess I am not very good at explaining things, hope this will be clear enough to understand.
