My stock power steering pump finally decided to leak, so I need to replace it. I removed all the bolts holding the pump in place, but now I need to get the actual pump out from between those 2 large brackets. One other thread on saw on here said to remove the bracket that is attached to the head studs. I would really like to not have to mess with the head studs, so could I just take off the 2 bolts holding the front bracket to the water crossover and the 1 bolt holding the front bracket to the other under the power steering pump? I hope that makes sense. From what I can see, it looks like I can get away with just taking that front bracket off but I was hoping to get some input from others who have done this in the past. Also, IF I do have to take the nuts off the head studs - how many lbs-ft do they need torqued down to when I re-install them? Thanks!
The bolts in the head that hold the rear bracket are studded bolts, so removing the nuts holding the rear bracket to the studs had no affect on the torque of the head. Once you remove the nuts and the bracket, it will be obvious that there is a head on the stud under the bracket that torques the head to the block. If you take the two bolts holding the front bracket to the watercrossover loose, you are pretty much guaranteed to create a water leak where the watercrossover attaches to the head, and then you will have to remove the AC bracket from the other side (if you have AC) and pull the whole water manifold to change the gaskets.
YOU NEED TO REMOVE THE P/S PULLEY TO REMOVE THE PUMP. It has a 3/4" nut & lock washer with a key-way. Once the nut is removed the pulley can be slid off fairly easily. If not it needs to be soaked with some kind of penetrate & tapped easily from behind. NEVER had one in a vehicle being used that didn't come off easily. If it has been sitting for awhile rust may have taken over & the task will be more difficult. Just MAKE SURE you don't damage the pulley. Tom T.
Forgot to mention. NO NEED to buy another P/S pump yours can be re-sealed easily enough by you. Seal kits are available at most auto parts stores incl. NAPA.
Brian, thanks for the input. I thought the nuts on those studs were the ones actually holding the head down, so its good to know I can take those off without worrying. I was afraid of leakage exactly as you described if i had to take the bolts out of the water crossover so I guess i'm glad i can avoid that. Telriv, i've seen a few different types of pulley pullers at the parts store. Some have arms that wrap around the pulley and yank it off (seems like a good way to bend the pulley) and some dont have arms on them and i'm not quite sure how they work (i didnt look too closely at it at the store). As far as making it easier to get off, would it be fine to soak the pulley in something like PB Blaster? As for the pump, I got a brand new pump/housing from someone off of the forums here so I figured I will save my old one to get rebuilt at a later time. Can't hurt to have spare parts! Thanks again!
The PS pulley pullers you see in the parts store are for the newer type pressed on pulleys that everyone switched to in later years. The pulley on your 65 has a woodruf key and keyway in it, and is held in place by the nut. Provided it is not rusted, it should slide right off--just be careful not to lose the woodruf key if it is loose!
Like tel riv says, a seal kit is easy to find. Its harder to remove the pump than to rebuild it. Also the high or low pressure or can get loose and seep. I did mine and painted it up nice. Its hard in the car
Well, I have bad news. I got the pump out and was super excited, the pulley slid off no problem, i got the key transferred into the shaft on the new pump, went to slide the pulley on and its the wrong diameter shaft! :af: So, i started to remove pieces from the old pump in hopes that I could figure out how to take it apart but I don't know how. I took off the 2 bolts that hold the pump to the rear bracket and the supply line on the back of the pump (along with the supply line came some other piece and a large spring). Can anyone help assist me in figuring out how to take this thing apart the rest of the way? I thought the front of the pump would just slide out of the housing. Alternatively, does anybody have a pulley with a larger shaft diameter or know where I could get one? Seems like pulleys are hard to find for some reason.
The replacement pump you have is off a 64 or older engine. The shaft got smaller starting in 65. There is an O-ring around the perimeter of the pump that seals on the inside of the sheet metal housing. It does just slide out, but takes some force to get it apart. When I have done it, I screwed some regular bolts in a few turns in the back where the studs go, then hit on them with a hammer while holding the housing in my hand. That will push the pump out of the housing. You also have to remove the pressure fitting since it holds the housing on as well. It has a spring and relief valve piston behind it, so watch for that. Past swapping out the housing, housing o-ring, o-rings on the studs/pressure fitting, and front shaft seal, I wouldn't recommend digging into it any further.
