fan hits crank pulley

[armand]

i have a red top sr and my radiator fan hits mt crank pulley, i had to put some washers in between the fan clutch and the fan so it dosen't hit the crank pulley. i was just wondering if anyone else has ran into this problem. also i am useing the fan from my ka24e could that have something to do with it. i thought the ka and sr used the same fan.

yea that has a lot to do with it...u cant use the KA fan on the SR. its bigger. ask 420xs..we ran into that prob when we did his swap.

also i was wondering if the fan clutches are the some or do i need to find one from a sr

[reccakun08]

im not 100% sure but all i know is that when i tried to use the sohc ka clutch fan it didnt fit bc of the crank pulley. and the dohc ka clutch fan clears the pulley. i took a close look to see the difference in either sr,kade,kae clutch fan but the SR and KADE is what you probably need.

the dohc doesnt work either...unless we did somethin wrong

I've compared the fans from a KA-DE and the SR, and you can tell that where the metal ring is on the clutch fan itself, on the SR, it's kinda got like a negative offset on it, whereas the KA-DE fan has like a 0 offset.

Because of that offset, when you go to put the fans on, the fan will either just clear the crank pulley or hit the crank pulley.

However, I think 1 of the motor's clutch unit for the clutch fan sticks out further and 1 of them is shorter, I can't remember. In either case, I must have the one that sticks out further, because I can use either the KA or the SR fans on my SR and they both cleared my crank pulley.
