looking at PS pump still attached to broken bracketslooking at area where PS pump mountsI replaced the power steering pump in my Mercedes and after Two days the mounts which are attached to what looks like the engine broke off. Not the mounts on the pump. What is the best way to fix the broken mounts? Thank you so much in advance for your help, I'm in a tough spot right now and not sure what to do.

    can you post pictures of the break? if it's aluminum you need to have someone that can tig weld do the repair or replace the whole bracket. – Ben Sep 8 '16 at 21:46
  • Have any pics to get a visual of what you are dealing with? – DucatiKiller Sep 9 '16 at 7:51
  • Thanks for the replies! I'll post a couple of pictures in original thread – Ryan F Sep 9 '16 at 21:09
  • @Ben I'm not sure if welding would work or not, to be honest. My biggest concern is obviously the strength of the weld and being able to hold since the PS pump is right on the corner of the belt and seems to carry most of the stress from the belt. As far as a bracket, I dont know if there is a bracket or if its a part of the engine cast itself? Both great questions, wish I knew the answers for. Hopefully the pics will help. – Ryan F Sep 9 '16 at 21:22
  • @DucatiKiller You're welcome, hope it helps! Thanks for looking' out! – Ryan F Sep 9 '16 at 21:23

Is that a timing chain cover that it bolts to? If so, first choice would be to replace the broken parts. 2nd choice, if its aluminum, get it super clean and weld it.

The problem you having addressed is that fact that it broke in the first place. It means it was over stressed and probably stressed in a way the factory never intended. I would lean toward it not being installed correctly (or even simply not being tensioned correctly). Use a torque wrench in the future.

It's because the screws are loose, the 2 of the low and the rear one. You only see the two on the top and they look ok, then the mount cracks apart.

Try welding and using a screw lock like Loctite in the 5 screws.

  • I don't know what they do in Argentina, but welding oily cast aluminum is going to be quite the magnífica solución artesanal. And I'm not sure how loctite will help with the OP's issue. It looks to me like expensive original brackets are needed, perhaps from a junk/scrap/breaker's yard. Best of Luck! – SteveRacer Nov 8 '17 at 3:11
  • Yes, agreed. Invest in new or used brackets. Some vendors even sell after market less expensive brackets. If the weld comes off good luck with all the accessories, crank pulley and surrounding irmc. – Numair Aidroos Aug 1 '18 at 5:40
