CB400F Cam Chain Tensioner
« on: July 31, 2008, 01:25:29 PM »
Hello.
Im new here, and I have a problem with my tensioner bolt on my CB400.
I notised a oil leakage, and I found out that the oil came from a broken tensioner bolt. The bolt has broke off just under the o-ring.

Does anyone have a fix for his prob?

If you're careful and patient, you can drill down the center of the broken bolt and use an extractor to remove it.  I had to apply some heat to the area as well to get mine loose after I sheared it off inside the hole.
