Vacuum Pumps

[z250kid]

What do these trucks just love destorying these? I replaced it three times on my fourth i went to ford this time got a new one. No reman crap. Hopefully it lasts. It only tal\kes me 15 min to change and pull the pully off lol

dont know if it would be the truck or the cheap remans that are the problem

Definately stick with OEM, there is no point in buying remans. We just had one changed(before I knew how to do it) last year and I am pretty sure it is already going bad, now we have a Motorcraft on the shelf for when it does go. They are more money, but it is worth it.

I read somewhere that these vacuum pumps are supposed to be filled with lubricant and there is an allen plug to do so. I didn't read this until after I changed and returned mine of course...and I ain't pulling it off just to look. I will next time though!

[kramarj]

Don't know about a plug, but they are filled with oil. I just had to change a bad one and was curious about how they worked, so it got torn apart.

Your power brakes. Pretty straight forward but you will need to loosen the A/C pump and move it to the side (don't open the A/C system just take the whole pump and move it over) so that you can reach all the bolts. Most places that sell the pump don't include the pulley. Getting the old one off is easy enough but getting it on the new one takes a special tool. pressing it on the new pump without the tool puts a side load on the new pump and can ruin it before you've even installed it.

You do not need to take anything off except the vacuum pump. Get a 10mm ratchet wrench and box end wrench or a flex head ratchet wrench. You have to loosen all of the bolts equally since you can not just pull them out because the pulley is in the way. Once all the bolts are out, pull it out until you can get to the clamp that holds the hose on the back and take the hose off, keep the clamp because you will need it again. Then you need a pulley puller, not one with jaws, but one that clamps on the hub of the pulley. Pull the pulley and use the same puller, but use it to install it, you can rent one of these pullers from O'reillys, I bought it from them, it was like $30. To install it I put the pump in the fridge or freezer and then heat the pulley in the center, not directly though, I set it on a piece of steel and get it pretty warm and install it that way. Make sure you put all of the bolts in first, otherwise you will just have to pull the pulley again. The idea behind the heating and cooling is that the heat expands the pulley and the cold shrinks the shaft, that is just what I read, works for me, not saying it is true.

I just used a 10mm wratchet wrench use a cheap auto zone puller also pressurer. Had it in a vice took me 2min to get the old pully off. New one same way just tighting the nut til it stops. If anyone in ct needs help with one let me know takes me 20 min tops to have it completly done.
