71 mustang 351c adding clutch fan
#21
I was looking at my fan clutch and I do have some sort of spacer. I have forgotten about it.
Please look at the picture and tell me if this is normal. If I reduce this spacer or eliminated I should be able to pull the blades back enough. However, they may be too close to the pulleys and belts.

Nope. that's not normal at all. Clutch bolts directly to the face of the water pump pulley.

Thanks. I guess that explains why my fan is so forward. In a "normal" installation, how close are the fan blades too the pulleys? Once I remove the spacer they will be very close in my case.

Well, normal blade depth past shroud opening on a FLEX fan is 1/4  width of blade, looking down from above, this allows for flex action to nearly close the gap, proving maximum cooling. Now a clutch fan has no flex, my stock ranger flex fan centered 1/2 enshroud opening.
