Cam cover woes

2007 T100

Just out in the shed replacing my cam cover gasket. When refitting the new bolts and seals, I stripped one of the threads. I had set the torque wrench to 10nm but hey ho it let go.
I initially went into panic mode, but once I read through some posts on here, the panic subsided, so a helicoil kit ordered and the cam clamp removed.

Should I look to order 2 new bolts for the cam clamp as well

More power to you if you got those two torx bolts out already, some apparently can be removed without setting the bike on fire, but I ended up having to grind off three heads when I replaced them during a valve check recently.

Here's a thread covering the complaints and the replacement bolts with hex heads that are a dream to work with:

Same torque for these as standard - Good Luck

Yes I managed to get them off, although it did break one of my torx bits (I wonder if that's covered in Halfords "lifetime" guarantee.
And looking at the bottom of it, someone has butchered it with a screwdriver in the past...Not me





I'll check out that link, cheers

Yep, there are butchers in the garage not just the meat market. Looks like it doesn't affect anything really, but I know I couldn't resist filing off the rolled side area.
Before the cam cover goes on you could write on the inside in permanent marker - No Screwdrivers!

I replaced those stupid torx bolts years ago with grade 8 hex head bolts from Ace hardware.
Not sure where you get them in Scotland This google link might help

The hardest thing to do with a helicoil is keeping it vertical. If you have access to a drill press, use that.

I just finished up my second valve check. First one was at 15,000, today was at 30,000. Every Everything was still in spec. One thing I learned about torque wrenches is that don't trust the cheap ones that you pick up in an automotive store. I purchased a 3/8 wrench for $25 in order to do the original check. I brought it into my calibration lab in work. The wrench was + 35% in the low range, climbed to be right on at mid range and - 35% in the high range. I would have stripped out my cap bolts if I relied on the markings. Once I knew where the 10nm was I marked the adjustment dial. I also marked the cap screws and the valve cover, and counted the turns to be sure. When assembling the torque wrench broke right when the marks were.

Last year I changed my valve cover gasket and triple-checked my torque wrench with the right settings before honking them down. Everything went back together fine.

Same thing happened to me when I was checking valve clearances the other month, those torx bolts are awful to remove. I figured that since I had stripped one, I might as well helicoil all of them. I ended up borrowing a buddy's heat gun and used a manual impact driver to get the bolts loose, and have replaced them with hex-head bolts as mentioned above. I don't have access to a drill press and was not confident in my ability to re-thread one cap let alone all four, so I took them to a local machine shop and they had them ready in a day for about $60 total.

I had same and was sh**ing myself doing the cam holders, it seemed way too tight. Tried calibrating like you and couldn't even get it consistent. Threw it away and use good old feel.
Was looking at digital torque adaptors, has anyone used one?

A friend of mine has had a Harley Davidson repair shop. He's been working on bikes for over 40 years. The only torque wrench he will use is SnapOn, he was 3 of them. Also sends them out every 6 months for calibration.
