Engine Cover Bracket repair

[M_alibu]

I have a 94 Echelon LX. The lower mounting bracket on the engine cover has broken loose. The screws have rusted and broken off. One of the holes is fine and the other has been wallered out. Poorbably from a previous repair. I do not know what the floor material is and what I am screwing into to determine what I need to fil it in with. I want to fill the hole, run the screw in, and let it set. Any suggestions on what to use?

Would it be possible to fill with an epoxy resin, drill and then use a bolt and nut on the bottom of the floor? you would have to have access to both sides. If not use an epoxy resin, let cure without the screw, drill a pilot hole and then screw in new stainless steel hardware. Read the lable on different two part epoxys to make sure the one you use is both drillable and machineable. This will allow the threads of the screw to cut in without breaking out the fill.

You could also try one of these imbeded into the epoxy. (or something similar)

I cannot reach both sides so the epoxy may be the way to go. Thanks for the advise.

Why not move the new bracket over a half inch and make new holes?

I would go the epoxy route. West Systems makes some really kick butt epoxies and adhesives that will make your bolt hole better than new.

Be sure to read their page on how to use it for fastener bonding. I would oversize the hole, fill with epoxy and insert a new stainless bolt after coating it in wax so it is later removable.

As well as like REW said, choosing the right epoxy for the job. For that application I would use the West Systems 404 High Density Epoxy made for gap filling, hardware bonding, and high load stress.

Just an FYI, the 404 has to be mixed with a resin and hardener (it is only a filler that increases the density and strength of the adhesive)

Good luck!

Nice I like the mod.

Good memory. I forgot about that one. It is sweet.

I should be in a different line of work. I amaze myself at the ability to remember such mundane things.

No doubt! You da memory master. I can't remember important stuff, but never forget dumb stuff like movie quotes.
