I was replacing the P Gasket and replacing the power steering pump at same time on my 95 Defender. No problems with the P gasket but found that the existing pulley (part ERR3733) doesn't fit the new pump ANR 2157. The existing pulley has a hole diameter of approx. 28.9mm and the new pump flange centering ring has a diameter of about 30.1 mm.

Only thing I noticed is that the new pump has a green dot on the flange and old pump had a yellow dot on it.

I don't really want to enlarge the pulley hole if I don't have too due to risk of making it off center.

Is there a different pulley available or will I need to bore out the pulley?

Thanks in advance!
