Default Stripped cam chain tensioner t27 bolt

Hello everybody.
I started the process of changing out the cam in my 2019 road glide this afternoon and stripped the upper chain tensioner bolt. Is it really critical to remove the tensioner if you do not plan on taking off the oil pump from the cam plate? I got the upper and lower gear off with the chain easily enough with the tensioner in place so do I really need to remove that to put it back together?
One thing I could try to get it out is putting the torx head in the bolt with JB weld and see if that breaks it free.

If you got the chain back on and everything is aligned right, no, you don't need to remove the tensioner.
That said, you could also use a dremel and cut a slot into the head and try to use a flat head screw driver or use an over sized drill bit to drill the head off, remove the tensioner, and then use vice grips to twist out the remaining.

Good luck man. Sucks.

Easy out, drill the head off, grind the head off, cut a slot in the head...do anything but leave a stripped out bolt behind your work. I wouldn't be able to sleep knowing I left a stripped bolt behind lol.

I've had it happen before as well. I just took a cold chisel and from the edge of the head of the bolt cut in a small amount then hit the bolt loose. Always cut in a small amount before hiting the chisel in the direction to loosen the bolt. Once it turns just a little loose they come out pretty easy and replace it.

Before I tried the chisel method, I'd take a ball bearing, set in on the head of the torx screw, and give it a few blows to sewage some of the material back into the socket. Then tap the torx bit into the the screws socket, the jolt helps loosen it, then turn out the screw and get a new one. It works nearly every time. I was a tool and die maker in two industrial facilities for 35 years and removed literally hundreds of problem fasteners this way. If that fails, you can go to the chisel method.

Interesting info about using a ball bearing. Never heard thus before, but will keep it in the back if my mind.

Yes most that have changed cams have run into the same issue. I used a small but sharp chisel also, a few taps and it loosened up enough to spin out with vise grips. not sure what cheap (crap) manufacturer made the bolts, I replaced with allen head.
