Calling all Tuscan V6 owners!

So, water pumps, are the early Essex water pumps the same as later ones?

I've just fitted a replacement and found that the generator no longer lines up, so it would appear that the new pump is about 4 - 6 MM. longer. Am l imagining this? If there is a difference where can one get hold of the correct unit?

I have moved the generator (alternator) forward to line up with the other two pulleys but of course that means that they are all actually running at a slight angle to the belt, obviously this is not ideal.

Thoughts, ideas?

They list out as all the same. It is possible that yours may have been to bits before and possibly machined down to account for wear / warpage perhaps?

I know that impellers have changed over the years and Adrian will know more than anyone which variant engine is in which car. Chances are he will know the answer to your question.

I do remember there was a different pump used in Scimitars (I had one) but I can't remember for sure what the difference was - I think it had an extra water outlet or one blocked up. No idea if it was a different offset.

The Colognes have different WP offsets - I mention this because they used different pump pulleys to match the pump. Is the same trick true for the Essex ?? Just a suggestion.

Old and new pumps looked identical on the bench, l bought the pump from Burton Power who do say they are the same (as you note, Neil) but l just can't get my head around why things don't line up now.
TBH l'm not too keen on having to take the pump off again just to accurately measure it and l'm not sure where that would get me. Maybe l could get Burton to measure one just to check that he one l have isn't somehow a rogue (pulley not correctly pressed on or something).
Not sure where to go next really (

Thicker gaskets?? Is that the reason they aren't aligned.
I would give Adrian a quick call.

Phil, here is a picture of mine. If you want me to measure anything just ask. Do you not have the old one to compare with the new one ?

Sandy.

[ATE399J]

Thanks Sandy.

I do have both old and new to compare and the new gasket is no thicker. I need to have a closer look at the positioning and 'depth' of the pulley, I think that may be the issue.

Hi Phil
I'm a little confused here. You have put a new water pump in and now it doesn't line up with the alternator yes? does it line up with the crank pulley? If the pump lines up with with the crank then the alternator is wrong. Do you have any pictures? There is no difference between the older and newer Essex water pumps so to be about 5mm out there must be something else wrong.

Hi Chris,

I guess it doesn't line up with the crank pulley either but from my viewing angle it was the alternator that seemed the most obvious and the only part of the system that can be moved. I don't think it would show in a photo, I'll get a long straight edge across the various pulleys next time I get a chance, that should reveal what's what.

I think I have had my basic question answered: there's no difference in early / late Essex water pumps. So it's either a rogue pump or my inability to wield a spanner.

Have you took your old pulley off or did the pulley come with the new pump. I believe they can be shimmed..Have you swapped and not shimmed or changed pulleys and lost shims?? Just a thought.

Did you take the alternator off?, you could have refitted it the wrong side of the bracket?
It would throw it out a lot though?
just a thought.

[GAjon]

The only pic i have from the top, unfourtunately the alternator is off but you can see the alignment to the top pulley wheel.

[ATE399J]

Pump came with pulley already fitted and yes, l had taken the alternator off but it was refitted to the "correct" side of the brackets (if it was the other side it would have been even further out). As l said, l'll lay a straight edge across the crank pulley- that one MUST be right. I'll then set everything up to that.

Check your old pulley for a shim?

It's too far forward at the moment, I'd have to take shims out of the new to move it aft wouldn't l?

[GAjon]

Can you take the pully off the new pump? has it been shimmed behind which would push the pully out????????

[chris52]

Looks as if there may be a couple of different pumps. The main difference is the the pulley on one is pressed onto the bearing with no adjustment the other is bolted on with 3 bolts and if you look at the picture below the bolted on pulley looks a lot closer to the pump body than the pressed on one although the picture is at a different angle so may be decieving.
