Well going down the road yesterday my vaccuum pump decided it was done with this crap and locked up on me. Of course the truck hasn't gone more than 10 miles from the house in 2 months and yesterday i go about 30 miles from home and it goes. Well i hauled it home(thank goodness for that other diesel LOL) anyway, i got this pump ordered. what all does it entail? It looks pretty simple so far, but I haven't look at it for more than a second. Thanks in advance.

 

Yep, it's not to hard. There are 2 ways to get-er-done.
If you have a Pulley remover/installer tool then it's straight forward job but....You can rent the tool from most part stores (free). Remove the pulley, then the pump and re-install the pulley.
No pulley tool? ...then remove the 3 bolts that hold the pump. Do it in stages as the pump moves away from the bracket. Most auto part stores will do the pulley for you. Be sure to have the bolts installed in there holes because they won't go in after the pulley is replaced. You'll see.

 

Words of wisdom on this one is get the pulley puller. With the puller its a half an hour job, and also remember to put the bolts on the new pump before you install the pulley. Good luck

 

not to hijack this thread but pertaining to this very topic... the only purpose the vacuum pump serves is to power the brakes? correct?

if so, then a hydroboost system would eliminate the need for the vacuum pump. what do you do with the serp belt that is now too long? just get a shorter one? or gut the vacuum pump so it is just an idler pulley?

reason i am asking is b/c i have a bad squeak and i think it is the vac pump going.

vaccuum pump is relatively cheap to replace....don't let it GO if it's going because mine locked up and made a mess of the belt....there is little rubber hairs all over the the engine. It also controls your heater switches i believe. there is a T on the fenderwell an it goes somewhere other than the brake booster. They make a hydroboost booster for these trucks however......

 

Right on scottie, No vacuum...no heater controls. You would need to add the SD electric vac pump

Fishy, Not sure but maybe you would just use the belt off a hydro boost truck but the PS pump would need to be replaced too.

 

Changing the vaccum pump would be a whole lot easier and less costly. The key is the pulley puller.

 

but where is the fun in that?

BTW... i think i found a sag pump that will fit our trucks that will out perform and outlast these CII pumps ford used. it's $80 plus $45 core (and yes they accept the CII pumps) plus no more plastic housings! it is a Cardone and can be found at RockAuto part #: 20-6244. I will be ordering one here soon but first i want to see if the fittings are the same. this will preface my hydroboost install

Pump change completed, took about 45 minutes total getting dirty time, including changing the pulley and replacing the serpentine belt. About 2 hours total time with the trip to the parts store. Super easy to do. Got what you were saying about the bolts jim, i double and triple checked to make sure they were in they before i reinstalled that pulley! Thanks all.
