Hi!
So this is my first ever repair/build up job and i'm also pretty new at tig welding..
The piece is probably not even cold as i write this im so exited about posting something :p

I should have taken my time to clean it better but i'm kind of happy with the end result..

I'll try to get the pictures in order next time :p

Looks like mercedes used to use some decent alloy in their pump housings, for the amount of cleaning you didnt do and the age of the pump theres not a lot of crap come out in the welds.
Good outcome.

Looks good man ! Some cast welds nicely and some not. Don't be surprised when you go to weld some other cast and it
just wants to become a bloddy mess . Congrats on the nice repair !

Thank you! It is really nice to get all of this feedback..

I have a 19" aluminum rim with a crack in it coming up..
it's been welded once before with a aluminumstick and it also needs a lot of pre-weld work..
Let's see how that goes :)

Nice job on the water pump - but please leave the wheel rim alone ! that's got bad news written all over it - unless it's used on a " res ride " at very low speeds & even then I'd not do it especially as someone has already botched it - legal implications for this outweigh any possible reason or price to attempt it.

Good advice. Pick your battles wisely. Let someone else get sued.

Yes you are right ! I did not even think about that...

It's my own rim and i'm going to try it out to see how it goes:) it's a beat up old thing and i want to try and weld something that needs preheat..


But thank you for the advice!!

EXACTLY! Perfectly said! I would have expected to see the oil boiling out! Maybe the part is relatively new?

It's a -78 original part:)


Owner called me after he put the part in.. He was really satisfied with fitment and there was no leakage:)
