HELP! 8v71 4905 Power Steering Loss

[Ryker]

Blew the o-ring in my power steering for the second time in 2 months. This time I am not at home and need to move by tomorrow morning. Is there a standard o-ring that I can purchase at a hardware store? How can this be prevented in the future? I have the original power steering, it uses standard 30 weight motor oil.

Is this Shepperd full power steering or assist power with cylinder? What o-ring and where are you talking about.

[HB of CJ]

I think, (not sure) that if you have power assist power steering and not full integral power steering you may be able to safely steer the Bus Conversion without the power assist working?

The Bus Conversion if it has such will revert to Armstrong manual steering.  Muscles required.

This may let you continue your trip and get you home.  When my good mechanic replaced my Victor VT42 power assist power steering pump with a bigger one along with the long hoses ...

... he took extra time to "center the system?" or "realign the system?" so that it worked properly.   Also took a little bit to get the air out.  When done superb power assist steering.

Hope this helps you some.  I do not know what kind of power steering you have.

I have the original power steering. I do not believe I have the shepperd. I'll look it up when I get home but I know it is original equipment, if that helps. I went to O'Reilly and picked up several o-rings. Put one in and it is holding for now, so I can make it home now. Would like to figure this out so it does not keep happening though. Maybe time to upgrade to shepperd? $$$$

Are you blowing the seal ring on the Vickers pump at pressure relief valve ?

[Ryker]

We looked it up in the book, and apparently I am blowing the seal in the pressure relief valve. So maybe the valve is bad? Also, the book says my pump is made by Sheppard and it creates 1,500 pounds.

That is a Vickers  with a Sheppard tag,that takes a square cut seal from Vickers a o-ring will not hold for any length of time

Yup, wrong o-ring.

[Ryker]

I called Luke and he said he sent me the the correct o-ring. If this is not the correct o-ring, where do I get the correct one?

[luvrbus]

Get the model number from the pump the seal will probably be part # 199390 or 262332  they are easy to find I buy mine from Power Steer Inc. www.powersteerinc.com the seal cost about 10 bucks and are easy to find on the net,fwiw I just popped a relief valve out of a old pump it is square cut   

[Ryker]

Thank you luvrvus! I will do that.

I ordered part number 262332 from Motion Industries. That part was for Vickers. I will let you know how it goes.

Motion is a great resource

Motion is a great resource

I wonder if he checked the pump model to be sure the 2623322 was for his pump ?

That's why having a Motion Industries within driving distance is a big plus They even had stepped key stock and offset keys
