I installed a rebuilt saginaw pump to replace the original on my 240. It came with a small o-ring with instructions to install it on the pressure fitting. I'm unclear what this means - does it go under the metal flange fitting on top of the pump? Thanks for any help.

 

yooo hooo .... ne1 there?

 

Just to finish this up for others who might do a search and find this thread. As far as I can tell, some of the compression fittings are metal on metal, and do not use an o-ring at all.

 

So, did you get it figured out in the end?

 

If your car has the remote reservoir it doesn't use the o-ring.If the ps pump has the reservoir attached,it uses the o-ring.

You didn't specify the year model of your car.

Thanks guys.

My car is an '89 240DL wagon - will add this to my sig as I'm sure I'll have more questions.

It does have the remote reservoir, so no o-ring required - thanks, this was the information I needed. The male fitting has enough of a ridge on it that I thought it make take an O-Ring.

I've tried various with and without the O-ring, and several different sizes of o-ring, and get a slight leak no matter what. Using PS fluid instead of AT, so that could be a factor I guess.

Unfortunately, I still get steering judder, apparently at higher temps, even with the new pump, so my basic problem is not solved. Will probably start a new thread on that. Hoses next I guess.
