I finally got my engine in and went to put the fan on and its hitting the dang Dampner, Anyone know what the deal is? I didnt see any thing the fluidampr site that said anything about any clearance problems.

 

Is your fan clutch tight? The belt lines up with the damper right? Mine doesnt hit. odd.

 

I had the exact same problem. As installed, the Fluidampr just clears the fan with maybe an eighth of an inch clearance. When running, the fan just kisses the face of the damper.

I ended up making what amounts to a 1/8" thick washer that goes between the big nut and the hub of the fan assembly. With that, there's now roughly 1/4" clearance. Running, it clears the fan OK.

Still though, I'd like more space but it works.

 

The clutch was new 5000 miles ago, the fan hits before the clutch nut even gets tight, I had to put 4 flat washers in the clutch to even get 1/8 inch clearance on the fan to dampner.

 

Silly question but is the dampner pushed back as far as it can go?

 

It doesn't push back like on a chevy small-block. Just bolts up.

 

Yes and the belt lines perfect

 

Whoops. I knew that.

 

the damper made of 3 pieces , the outside-metal , the rubber middle part , and the inside-metal , some times the outside part slips off the rubber .
Can you see if the seal is riding on the same old spot on the damper ?

 

no rubber ring on the fluidamper... its a viscous damper

 

The Fluidampr is of totally different construction. http://www.fluidampr.com/HOWITWORKS.htm

 

I dont know much about hotroding diesel's. But be very careful useing a fluidamper , know from experience. Dont care what they say and they do go bad. thats on a racing small block chevy at hi rpm's.(8700)

 

Actually, Cummins has used a viscous type damper in a number of applications. In the industrial setting, Cummins recommends a through inspection every 2000 hours or two years.
They (Cummins), are very specific that the fluid will become hard with time.
