Don't see why not. The clutch is sealed internally to keep fluid from spewing out of it.... Anything that will hold fluid pressure should hold air pressure too. Air activated may be much easier to do than going the P/S fluid route.

They are different connectors.... Is the connector on your truck that plugs into the PMD black or gray?

Google search the serp pulley part number, I see at least 2 places that appear to sell it.

Reliability is alright.... Biggest problem to be honest is the electrical controller (little black box). It goes out, then the fan doesn't come on. If you were to rig one of these up with a toggle switch, to turn it on whenver you like, it would be great. I can tell you these fans and a fully...

You may have gotten air into the fuel system while you were cleaning the screen in the FFM. Your black PMD won't work in place of the gray one. The connector is different from a black PMD to a gray one. If you want to swap a different PMD to see if that's the problem, you will have to get...

This info is all Military..... The Army acronym for a hummer is: HMMWV ..... which means High Mobility Multipurpose Wheeled Vehicle, but figured hummer was more easily understandable. It's actually the same exact fan clutch for both v-belt and serp setups. The pulley (either v-belt wp...

To answer your questions; The fan clutch is hydraulically controlled for "locked" or "unlocked". It uses power steering fluid pressure routed through an elctro-hydraulic solenoid that locks up the fan clutch just like a clutch pack would be in an automatic trans. The solenoid operated (to...

No problem, start a new thread on this and I will post pics and talk about how it works. Don't want to hi-jack this thread.

Yes on both accounts. You will end up using two wrenches at the same time, one that holds the pulley still and the other grabs the fan clutch and loosens it.

There is a special tool for that.... Most of the chain parts stores rent the fan clutch wrenches to make it easy. Sometimes you can pop the clutch loose with just the tension of the belt holding the WP pulley.

Good advice

Buddy, I agree.... However, I guess my interpretation of what he said/meant is a little different than how it comes across to someone else reading the same thing. Here is how I interpreted the OP...... These are merely my interpretations of what I read in the original post, your...

You should see an "edit" button at the bottom of your post next to the reply and reply with quote buttons. Hit "edit post" and you can bust it up into paragraphs.

Short answer, yes I think it would be worth $900 for the parts you can get out of it. You would have everything you need to do the trans swap, minus maybe the driveshaft.... Not sure of the wheel base differences between the CC C3500 and your HD. Also the rear crossmember for the trans, I am...

X2 Very well said.

antifreeze going into the combustion chamber, through a crack or bad head gasket, can cause low power and white smoke. If it's been doing this for a long time and you haven't been losing antifreeze....then that probably isn't your problem. Does it seem to run alright while it is having low...

Blueish white smoke is normally bad news..... Especially enough smoke to get a ticket..... Do you ever have to add oil or antifreeze to the engine? If so, how much and how often?

His website seems to be down right now...... Here is a link to his ebay store. http://stores.ebay.com/Teds-Trucks-N-Stuff/ENGINES-/_i.html?_fsub=17301160&_sid=30960605&_trksid=p4634.c0.m322

Tell us more about what kind of truck you have..... Year, model, F or S engine code, is it all stock or have you done mods, how many miles, any smoke from the exhaust, etc........ We will definately help you out, just have to know a little more to get started.
