    My steering pump was leaking and finally decided to fix it this morning. Turned out being the pump housing was bent where it mated with the actual pump. Luckily I had a spare and was able to replace it. Now that it’s back in the car the pump has about an 1/8” or a little more of end play. I do recall before it also had some end play, just can’t remember how much. In the process I also noticed my v belt was really bad and replaced it. No noises with the engine running and the test drive seemed all good. It just bothers me a little that I can see the belt follow the end play of the pump. Is this ok? If not how can I reduce some of the end play?

    Mine does to, doesn't leak from the shaft seal so I don't worry about it!

      Did you open up the pump section? Man, been probably 25 years since having one totally apart....but seems like I remember a spacer washer being in the housing? Got to have a little bit of end play but 1/8" is kinda a lot.

      The shaft is floating in the rotor, the rotor is driven by a round pin being used as a key so the shaft doesn't apply a thrust load to the rotor... It's normal...

        Probably don't have anything to worry about....but I just remembered that I have one on the shelf that probably has 100k miles on it.....1/32nd" end play. That's almost a spark plug gap. I'm thinking you may not have 1/8" end play on yours?

        I did any warrantee pumps back in the day working at the dealer. Most had quite a bit of end play. Never hurt anything.

        Great, thank you. 1/8" to 1/4" still within specs?
