Motor Mount Repair

This cast aluminum 2.2 liter engine block came off a 1996 Honda Accord that had been involved in a minor traffic accident. The front motor mount stud was broken off, and cost the customer around $1900 to replace. ($1000 for the motor, $900 for the labor)

Steve at Alternative Automotive in Sarasota, FL was hoping we could save this rather than scrapping it, so we grabbed our Super Alloy 5 and an oxy-acetylene torch and went to work.






A close up of the broken stud.






Super Alloy 5's flux allows us to make the repair without cleaning off the oxidation. We pre-heated the entire area for 2 or 3 minutes before starting the repair, to get the aluminum up to temperature.






We used an oxy-acetylene torch to allow us to keep
the cast aluminum at a constant temperature of 600 ^o.






We've begun to build up around the broken stud, laying layer over layer of the Super Alloy 5 into the gap.




Watch for the cast aluminum to look slightly porous, indicating that the rod will flow into the metal. Always use a dark pair of glasses for eye protection, as well as to enable you to see through the bright flame.






After only 10 minutes of work and $49 of Super Alloy 5, this engine is ready to be cleaned up and re-installed.

Thanks Steve!
