Series 2 Water pump seals

G'day folks,

I've got a question for those who have fixed their water pumps in the past.

I bought a kit from Craddocks and took the pump to bits. All went well except when it came to fitting the seal. The seal that was supplied in this first kit had a transition fit on the shaft =>





This stopped the shaft from turning properly - silly stiff - no V belt could turn it. So I took it apart and bought a kit from Paddocks. The seal for the pump in the second kit came with a massive clearance of about 4mm on the shaft =>



Hmmm

Difference.

Which is correct?

(I'm assuming the tight fit is not correct but then there comes to mind the idea of sealing and coolant ****ing its way past the seal...)

Question

1) Who has done this job before and remembers how tight or slack the fit for the water pump shaft was when they did it?

Trouble is I think there have been several different producers of replacement water pumps over the years.

Yeah that doesn't surprise me.

I have found an impeller with a smaller diameter shaft though so it could have been a simple case of wrong part in the wrong box.

BUMP for anyone who has done this before!

Did you ever find out? have similar issue: seal way to tight for the shaft to turn (shaft diameter is 0.2 mm larger than the seal)

Life is too short for pump kits. I just bang on a ready made up cover.
They ain’t expensive

There is one of the early s2 pumps that are rare or nla, and Iirc no on makes a replacement one, it was either 7 or 8 stud cant remember which.

I am sure there is a UK company that repairs/recons coolant pumps, not just land rover but all coolant pumps, might be worth finding and contacting them.
