I used to like ACDelco but I am starting to think otherwise. I am in the auto gate buss and use a lot of marine batt. and I am starting to have a lot of warr. calls. Also my fan clutch (Acdelco) is about 10 months old and she just went south. Bought a new clutch today and it is made by Hayden, anybody ever heard of them? And cost was 120.00 plus tax

Hayden has been around a long time, as has ACDelco.. I've used other Hayden products in the past with good results (electric fans, trans and oil coolers, etc.)

Hayden are good products. I've been using them for years! No major problems with any of them.Sent from my DROID RAZR using Tapatalk 2

I understand that using OEM Cummins fan clutch is the best. May cost more but will outlast any over the counter clutch.

can anyone share how free the clutch should be cold? I saw Mikes video of the eng running and holding the fan but is that how free it is just sitting cold? Is there drag at first then it spins free? I have more drag on mine then i would feel comfortable putting anything in the fan blade. I just noticed the hub bearing is bad also..:banghead:

Just with the engine off and sitting cold it should be very stiff. After you rock it back and forth a bit it should let go a wee bit but it will still be fairly stiff.

bout how long till its loose like in your vid?

i wanna see a video.

For what's in the video the engine has been running a least 60 seconds or so to spread the oil in the clutch then you'll hear the clutch unlock. Takes longer in time or more RPM as the oil get colder to unlock the clutch.

Hayden used to be a leader in quality fan clutches. Bought one for my old dodge in 1993 at Pep Boys with a lifetime gaurantee. Put the recipt in the box with the old clutch. About every 120,000 miles I take it back and get a new one. They put the lifetime gaurantee on it but didn't expect me to keep the truck for life.

got the Hayden, first one would not unlock for the first 65 miles or so.. took it back second one will unlock after about 10 miles then is ok.. seems a bit stiff but will give it a bit and see it it gets better..

Which fan clutch is the one you are using? Cummins replacement? I got a new one from Napa today that is supposed to fit a '95 (no first gen clutches in stock), and I let it run for about 10 minutes, drove it, and it still never unlocked a bit.

I'm still running OE clutch.

I see. Would you happen to know the Cummins part number for it?

Sorry I don't. But you could get one at the Dodge Dealer but you'll pay for it.

Of course. I just remembered about a guy who lives up the road from me that repair Dodge Cummins all the time, and he's got dozens of engines just lying around. I think I'll go up there and see if he'll let me have a stock 24 valve clutch.
