Fan Removal

Biggpigg4x4 · Feb 27, 2015

Trying to install dual fueler on my 6.7 can't get the clutch fan nut to break loose. Pulley keeps spinning on the belt. Anybody had this issue? Are these reverse thread or normal? I know opposite of what it runs, but the trucks in too many pieces to run at the moment. Thanks in advance.

Probably reverse thread. Engine should run clockwise. May help to have someone push on the belt to increase tension while you bust it loose.

I think that the 6.7 rotates counterclockwise

The 6.7 spins off counter clockwise. 6.4 fans are clockwise.

Sorry thought he meant engine rotation :morons:

When I had to pull the fan on my 7.3, I ended up using a one inch ratchet strap to hold the pulley. Each end hooked to the frame and it was wrapped around the pulley a few times. This was because I didn't have the right tools.
