#1 water pump
Posted: Fri Jun 28, 2019 4:48 pm
Dear forum colleagues,
each part I remove from my car seems to be damaged.
I'm already thinking if it is reasonable to continue the renovation.
Today I just wanted to remove the water pump to send it in for refurbishment.
But I found heavy damages due to cavitation.
The pump body and the engine timing cover show severe wear.
Is this normal for a e V12?
Did you experience similar problems?
I thought that refurbishment of a water pump is a straightforward job. Take it out, send it to SNG, get it back and ready.

Only you can decide if it's reasonable to continue your restoration. So many factors apply: available funds, available skills, available space are simple ones, but also consider the importance of the car to you and the importance of the car historically. At the end of the day it's your call, but there's nothing on an E-type that can't be repaired or replaced.
When you send your water pump to a supplier you get someone else's refurbished pump back, so the damage you're seeing on your pump will be the supplier 's problem to fix.
That said, the early cars had a different casing to the water pump and they're difficult to find. I got mine from a company in the US. PM me if you need their details.

What Nigel says is true, both regarding to the continuation of a restoration and the early pumps. However, once the restoration is complete I’m pretty sure the feeling of satisfaction will be worth the effort.
Regarding the pump, I’m not sure if it’s still applicable, but I have an early pump and although SNG could not exchange it, they did offer a rebuild service, which I used satisfactorily. You get you own pump back, I think the internal parts are similar, maybe bearings are different. The main difference is the casting as I recall. Check the engine number against the parts manual to check which pump you should have.
Good luck and don’t give up. I’m sure your car is in better condition than mine when I started. If it runs, or is mostly complete, then it will be. My car has now been on the road nearly as long as off it (in my ownership) and I am really happy with it and glad I stuck with it.
Regards and good look,

Hello Nigel, hello Simon,
I have decided to send it to SNG and they can judge if it can be reused.
Both engine and pump side show wear due to cavitation problems or corrosion.
Thank you for your advice.
I will continue the restoration (of course) because my wife bought the E for me to avoid that I start one new project after the other
We are both mechanical engineers and have been dreaming of an E for nearly 30 years.

Sven, please let us know a how you get on with SNGB.
Oh, and you're a very lucky man to have such an understanding wife!

Yes my wife bought me my car too! She’s not a mechanical engineer, but still I am very lucky.
