Fan and Power Steering belts

Thanks Guys,

I got a little side tracked and haven't checked back for a while. I am now running the TRW pump (Federal style) cast iron water pump and all the correct brackets and pulleys, no a/c. I measured the belts with a tape measure and learn't that's not a good idea as they sit down a ways in the groove and the tape doesn't! Got there in the end with a bit of trial an error. I will have a look tonight at the width, what does the 13 series measure across? I'm on the other side of the World so easier to source them locally.

While I'm at it - the power steering pulley is quite a bit mis-aligned with the crank pulley, both in the horizontal and vertical planes. I improved it with some shims and it is OK, but how much tolerance did they have from the factory? no adjustment in the brackets and they look straight and the pulleys run true on their axis.

I'm also curious about the difference in the TRW and Federal pumps, the rebate in the reservoir (and brackets) is different but are the pumps dimensionally the same?, are they the same internally? I know there are two versions of the TRW pump with different flow rates and different internal bypass systems. How do they compare to the Federal pumps? Can I use a Federal rebuild kit on a TRW?
