RE: Fan clutch stuck? The tool I used to fix. (05-30-2019 )Chamberpains Wrote: Mr. Loo there may be a psi reducer before the solenoid or the solenoid itself may reduce the pressure to only 90 psi. They don't need more than that to operate and International is known to put reducers in line for a lot of things. I'm thinking you are correct on the International side with the solenoid. By all rights it should have broken loose with the air the truck compressor built up. Either they are reducing it or it will not activate the solenoid unless the cab controller shows the motor running. As far as the plate on the clutch, it was much easier to remove the two nuts and worm gear clamp on the air filter than it would have been for me to get at the fan clutch with a wrench. Very little room up there with the front structure intact. And the push pull connect removal pliers made this job a breeze. | |||

RE: Fan clutch stuck? The tool I used to fix. I suppose you can keep your rig in the truck and just connect it to your seat blow gun and have it out on the road with you too. I've stretched mine out the window a few times to diagnose fan clutch and air controlled turbo actuator problems. | |||

RE: Fan clutch stuck? The tool I used to fix. Wish you guys posted this earlier! For the second truck I’m slowly doing up, I’ve gone and purchased a new clutch assembly. Did previously try the airline to the compressor and even wd40 but never tried the hammer! Will do this tomorrow! If she doesn’t budge I’ll loosen those bolts on the rear. The good old hammer trick! Thanks guys | |||

RE: Fan clutch stuck? The tool I used to fix. Sometimes a two wire solenoid will short to the case. These are usually bolted to something metal. The short will cause problems if the solenoid is ground controlled thru the one of the two wires. A while back had a run of bad ones new, right out of the box bought from OE in this case Navistar. To get going ended up strap tying them to the wiring harness bundle. Then they worked fine. | |||

It is held in an adel clamp that is insulated with rubber bushing. User's Signature: ->: What I post is just my own thoughts and Opinions! --- I AM Full Of S__T!. | |||

Just being long winded for the guys like myself that have read about using air to release a stuck fan clutch, have no clue on how, but want to know how IF you have a CAT they will not disengage the fan clutch until 30 seconds after they sense RPM. So, unless you have CAT ET to send a command to disengage the fan with the engine off you will have to use Waterloo's method. | |||

So, unless you have CAT ET to send a command to disengage the fan with the engine off you will have to use Waterloo's method. That is how it was acting, as if there was no signal telling it to disengage. I had more than enough pressure built in the system, well over 120 psi according to my gauges. As soon as the direct connect with my shop compressor reached over 90 psi, the clutch popped. All is good now, working as it should. And that new remote ball valve I installed at the heater core has already paid for itself. I was running early this morning and ran right into a tropical monsoon here in Ohio, LOL. I needed heat to clear the glass, thank God I installed that valve. Right in the construction... It was not pretty. | |||

RE: Fan clutch stuck? The tool I used to fix. I end up getting mine unstuck but found the fan had abit of play, might have to change it after all. Don’t want that thing flying off and puncturing the radiator. | |||

Don’t want that thing flying off and puncturing the radiator. Most {borg werner} fan clutches have a little bit of side-play in them when they are in free-spin mode. Only question needing answered is if it is more than normal. User's Signature: ->: What I post is just my own thoughts and Opinions! --- I AM Full Of S__T!. | |||
