KDP fix/Fan snug/warning

[Tardog]

Just a precautionary note, I did the KDP fix last week and all went smooth, piece of cake, great jig design, good instructions. Just incase, and I'm sure I'm probably 1 in a 1000 or more but I "just snugged" up the fan as per directions as it should tighten as it runs but heres the kicker. I drove the truck loaded for 400km in the bush up the hills and down the highway everything was running sweet since the fix. Then I got into heavy stop and go traffic on a 75 degree day and the truck began to heat up to a point of hearing the fan kick in and operate while we sat still. 15 min later, "shwing" the fan spun off and punched a hole in the rad. I guess the resistance worked against it. Nothing major just poked holes in 3 horizontals. Lucky for me it was right at the top dead center where i could get at it. So out with the torch and solder and a bucket of water and setting the fan with a 10lb sledge and we were on our way. This is by no way a flame or critisism just a precautionary note to those that are going to do their KDP. Please tighten the fan well, don't expect the motor to do it for you and let me be the only one this happens to. Cheers

Good warning. Sorry for the bad advice, now you have me worrying about the hundreds of jig users who may have potential problems. Still trying to figure out how it's even possible for the fan to turn the other way and unscrew. For what it's worth my fans have been taken off at least 8 times since they are removed for winter and have only been hand tightened when replaced. They were just as hard to get off every time as they were the first time.

Tardog, thanks for the heads-up. I like illflem, tightened mine hand tight. When second guessing and doubt got the best of me and I checked it a few days later, it had self tightened.



Sounds like you had a bit of bad luck, and the perfect set of circumstances to cause the problem. But I will put the wrench on mine next time it's reinstalled.



Thanks, Ronnie

I just reinstalled my fan and I only spun it on hand tight. Like the others, I thought it would take care of itself. I guess I will get the wrenches and check it out. Thanks for the heads up.

Retightend with a 3# hammer & punch...

Thanks for the warning. I'm sure we'll all be more careful in the future, but can anyone come up with a theory to explain this scenario? I'm really puzzled as to how it is possible.

dremelts,



Another local guy Where in GR are you? Shoot me a Private Message if you'd like.

Illflem, the key to his story is he was in stop and go traffic and the fan running. with the fan hub viscous (locked up) if you let off the throttle quik, all the wieght of the fan goes into spinning the fan backwards. rather the fan slows down slower than the engine. this is the second time i have heard of this.



hope you guys check them out. sounds like this guy was more than prepared with a bucket of water and torch, flux and solder.



i know i dont carry those items

 

[Tardog]

I wasn't quite as prepared as you give me credit for. The water came from a Wendy's resturante and the solder came from a hardware store nearby. I did have the torch, sledge hammer and misc. tools. I am a bridge contractor and many times logging bridges are in remote locations so we tend to carry alot of goodies. Just like a air fitting to fill our tires off the oxy bottle after we patch them by hand and set them with a can of ether and a flame. But your right, I too figured it was the inertia in the fan, it does make sense. Check those fans.

 

[moparguy]

Tardog, I didn't know you guys in the Great White North knew how to set a bead with ether and a match. More than one log skidder tire has been launched into low earth orbit down South by a hand getting a little over generious with the starting fluid when fixing a flat.

We eskimos have many tricks, like wack'n phords on their mirrors with frozen fish when we go by them.

Tardog. . very good one...

we need to do a fresh remote woods thread. . our tricks, like busting the beads, radiator repairs like tardogs, broken 4x4 front end fixes,u joint repairs... etc,etc,

 

[Tardog]

I'm sure after reading this site for 6 months we could write a book on all the tricks we have up our sleeves, pant legs and other dark orifices we have. We can all amaze ourselves when put in the right situation. Had a boken fuel pump on a carburated engine out in the bush (not to far though) so we filled up the washer reservoir with gas, rerouted the rubber lines to the carb and vola! away we went. (real jerky though, tough keep'n coffee off your lap or from chok'n when the "G" forces forced it back into your throat) :-laf All in a days drive. The thought of a book of tricks is interesting though?
