You will need these tools

Then the 3 bolts that hold the pump & IIRC one vac line

After the new pump is on ,re install the pulley ,,I would get a new pully also , they can only be pressed on a couple of times IIRC,,

you can rent or borrow the tools from most part stores ..

One is a puller ,,the other is to press the pulley back on...

Vacuum Pump and Bracket





Item Part Number Description

2 2A451 Vacuum Pump
3 3A674 Power Steering Pump
4 26487 Vacuum Pump Pulley

Now, when I did mine I didn't have to remove the fan and shroud I just got in there with my greedy little fingers. I don't remember removing the bracket either. IIRC there is a hole in the pulley that you can use to get to the pump bolt behind the pulley. The pump should come out by itself with the pulley attached. Then swap pulleys or in your case put the pump in with the new pulley.

 

[quote=Cuda_jim;6527703]Does this mean the pulley is difficult to turn by hand?/quote]

yeah...it turns but most def NOT freely...

found this: eBay Motors: FORD 7.3L DIESEL MECHANICAL VACUUM PUMP (item 140265324978 end time Sep-13-08 05:01:40 PDT)

which will leave the fun part- figuring out how to get my truck and my free labor (i.e. buddy who knows way more about diesels than me!) in the same place so I can learn with supervision

 

Where in Va are you? I am near Bristol.

 

Toano- northwest/just outside of williamsburg

 

so how often do vacuum pumps usually last? what should i watch out for next, given that i don't know if/when most parts were replaced?

 

What kind of fans did you install? Where did you get them? Or is this a "build your own" fan set?

I want to try electric fans, but am not finding anything to my liking.

 

My vacuum pump lasted nearly 136,000 miles. After seeing the excellent instructions and illustrations, I wish I'd tried it myself. I also wish I'd known the fan needed to be removed. I would've asked them to leave it off.

Oh well...another project for another day. Good luck with this.

 

Is it possible that the pulley was installed backwards? I am only asking that because looking at the old paint left on the pulley, it is on the engine side.

I think if you pull the pulley off and turn it around, press it on until it is flush with the shaft I think your problem will be solved. Be sure to add a bit of locktight as mentioned eariler.

I hope this helps

i have seen them pullys walk out befor i did put a bot and washer i one i had do that years ago

 

$100 for the pump shipped. Seems my pulleys have evaporated. PM me if you want it. I dont seem to get over here that much.

 

this whole press-fitting thing seems like a very insecure way of doing things...it's gonna take me a while to stop expecting the brakes and steering to cut out again ~

so if everyone keeps taking fans off and leaving them off...then exactly what purpose are they supposed to have??

 

Leaving the fans off shows just how good/huge the cooling system is on our trucks w/o overheating. But you need to keep air moving over the radiator...that's where the fans come in...very hot days sitting in rush hour traffic. Running down the road should be OK...even pulling big loads.

 

Run the fan. on some trucks and the way they get used, its a good thing. Saves you from running the risk of overheating somewhere.

The pulley presses onto the shaft of the pump from the factory. Once you do it you'll see how tight. The design works. All the bolt in the end of the shaft would do is hold the pulley on? Not needed and leaves something to rattle loose and fall out.

Some parts stores will even rent the puller set. It grabs on to the center hub and pulls it off of the shaft.

 

also saves the trouble of having to store it w/o a garage or even a shed LOL
