(108) 4.5 power steering pump- reseal anyone?
I couldn't find anything in the archives about resealing the power steering pump on the V8- the one in my car leaks like a sieve, I have a spare that I have bought the reseal kit and new filter for- now, has anyone taken one of these apart to replace all of the rubber seals?
I'm thinking just getting the pulley off might tax the limits of my tool collection right there... Anyone done this on the notoriously noisy 4.5 pump? Thanks- JAS |

It's easy enough to find a spare. The local Autozone has what looks like the right tool to remove the pulley. One of these days, I'll buy it and try, since I have several spare pumps. -CTH

I used a generic autozone puller to get my pulley separated from the shaft. A well-placed blow to the pulley while under some tension is usually enough to get it apart.
The reseal process itself is not too difficult. There's not too many parts involved and if you take your time, you'll have no problems. I believe the puller is the only special tool required. I had a step-by-step 'how-to' article around here somewhere -- I'll post it if and when it's found. |

jmela-
Sounds great- if you find that 'how to' article, please post. I'll pick up a puller at autozone or etc this week and try that. Thanks all- -JAS |

jas2wa: here's a description of the process, not thorough nor the one I was looking for.
"Here's two step-by-step Getting the pump off isn't alot of fun. I remove the rad and the pulley from the pump. You have to take this pulley off anyway but pump removal is impossible without doing this. Remove the pump and split it in two. You will probably see two seals or O- rings. One big the other small plus the main seal on the shaft. A small screwdriver or icepick to get the old seal out, then clean everything up and press in the new seal. I used a deep well socket and a soft hammer. Replace all three and put it back together. The pulley can be challenging to remove. Have a beer handy." PS. I was able to remove my pump without pulling the radiator. Take a look behind the steering pump pulley and see if you can reach the bolt with a wrench. My attempts to remove the pulley w/ the rad in place were in vain - all I did was ding up my radiator fins. I'll keep looking for a better description... |

This is a great help.
As it stands, I have a spare pump out on my workbench- has pulley on it and everything. I want to take it apart, reseal, and then swap the whole thing out for the one in the car now. It seems what you are saying is that if I have the whole thing together, I'll be able to swap w/o removing the rad? Gee, hope so...! This is my project for the coming weekend. Thanks for the input. -JAS |

Pulling the rad is cake anyway. Probably easier than getting the pulley off.
Just remove the 4 (10 or 12mm) bolts on the fan. Remove the shroud, drain the radiator, disconnect the hoses. Remove the oil cooler and transmission cooler hoses and plug them. I used foam earplugs, works well. On the oil and tranny cooler hoses, I put the open ended wrench on the nut and gave the wrench somewhat gentle taps with a hammer to break things free. The rad should lift straight up. Take the rad to a shop and have them clean it out for good measure. Shouldn't take more that 30 minutes to free it.

slow going---
Has been a busy week, just now getting to mess around with this pump again- if I could get the 22mm nut off the end of the pulley, the puller I picked up would work great I think to get the pulley off. Then I could actually get the mounting bracket off the thing to take it apart.
Also, does anyone know the size of the hex bolt inside the fluid reservior? (My guess is 14mm- nobody in town sells a hex key or even hex socket any larger than 10 or 12mm, so yet another set-back to getting this thing apart...) One of these weekends... Advice appreciated! Thanks, JAS |
