I think Vickers and ZF were both OEM suppliers?  I swapped the PSP off the donor 420SEL onto the 560SEC and they look the same but had different tags on them (or on one, the tag was missing but it was clearly in a different place/size).  I'm pretty sure one was Vickers and one was ZF.  I tried to find some details and on one of the forums it suggested they were different internally, so different seal kits, but externally the same.  I forget now which one was leaking and which is the "new" one but they both came off the cars and looked to be original.

Thanks Craig,

I looked at the A1Cardone and it it not available (for my 91 300D) and it may be a while before it is available.

So I am back to the used pumps offered.

1 Question - is there any difference between the Vickers and ZF pumps?  I "assume" they are manufactured to identical MB specs ?

I spoke with our local dealer who told me his computer says I should look for these 2 pn's:  1244600280 or 1244601780.   The 0280 # matches my current pump.


Any ideas about ZF vs Vickers?

Thanks ya'll!

Larry,

That looks to me like a complete break of a tab on the body of the
pump, so you'd need to replace the entire pump.
Yes, that's what it looks like to me, too.

I'm in a similar situation, with a power steering pump on our 1990 E300D
that's leaking. I have the choice of replacing all the seals (assuming
the pump is really good) or buying a new pump. I have found a seal kit
for about $18 and an A1CARDONE pump for about $70.

Is the A1CARDONE pump a reliable one, or should I just reseal the one I
have? Of course, if the A1CARDONE pump is reliable, that would be an
option for Larry, too.
