Broken bolt timingbeltcover

Post by Dutch_Hans »



Hello Wingers,
A few weeks ago a deer ran into me when I was driving 70mph.. a lot of plastic is broken but I managed to keep myself and my gl1500 upright..
I found a lot of plastic which is now being sprayed. But the timingbeltcover had some cracks too.. I've loosend all bolts but one of them broke..
It sticks about 3 mm out... What can I do...
Every help is appreciated.
Greetings from Holland

First, SOAK it in an appropriate lubricant for at least a day.

Then, carefully try to remove it.

If worst comes to worst, you can drill it and rethread.

Depending on which of the bolts it was, you may not even need it -- the timing cover is not a critical component, it just keeps dirt and water off of the belts and pulleys. Just use gasket goo when you reinstall.

Thank you very much for your quick reply.. it is the lower middle bolt from the left(big) cover.. I am soaking it with wd40 every half hour, the best I have at the moment. I thought the cover was pretty critical because when a belt brakes...its over... I will spray it in for a few days before trying anything else and hope for the best.

The timing cover is just a cover. It isn't load-bearing, doesn't hold pressure or fluids. Consider that dragsters don't even HAVE covers over their timing belts.

Yeah, I figured that the bolt was a permanent part of the engine now -- they're not all that easy to break. My guess is that it got corroded into place.

If this were a load-bearing bolt, or critical in any other way, I would have advised drilling it out (carefully!) and either re-tapping to a larger size or putting in an insert.
