I was installing the 8x26 bolt used to secure the left engine guard to the front of the engine and got it cross threaded a bit  Can someone tell me what the pitch is on that bolt? Options are .75, 1.0, 1.25 I don't have the bolt in front of me and need to pick up the correct tap while I'm out and about. TIA |

A tap is not the thing to use to clean up threads.
Doing so will end up with less threaded material and a weaker connection.
A thread chaser is the thing to use and should be a lot less expensive too.
The original bolt would be a good thread chaser if you clean up the threads with a pick and can get the bolt started correctly.
Naturally you have to get close to the damaged threads and have good light and good sight to be able to be successful, but the effort would predict a good outcome.
Using a tap is no guarantee anyways. I mean, what's to insure that the tap will start in properly and straight. You chance just screwing up the whole deal completely and then needing to be fixed with an insert.

The 8mm bolts should be 1.25 pitch.A tap or chaser works well as long as your gentle and use lotsa lube  bw |

I have had the engine guards off many times and stripped the right side to the point where a tap was usless. A helicoil worked perfect  |

If ya screwed up the threads, a Helicoil works wonders on your screw ups.
Don't ask me how I know that.
Remember, aluminum is very soft.

Thanks for the replies. Where I went wrong was by trying to install that bolt while all the others were were tight. I coudn't quite get the opening in the guard aligned with the bolt hole. Tried to force it and....CRAP. What makes it worse is that I know better than to do that.  ...Dumbass |

Thanks RJ. I'm quite familiar with Helicoils as I have used them on several occasions to mend my screw ups  |

I keep an aluminum inspection plate on the engine guard bolt under the radiator hose. As soon as you pull it, it springs the guard mount hole off center from the frame hole. Needed to loosen all of them up, but I didn't, just torqued her in tight and cross threaded. Just slap the annual inspection sticker on the plate without removing it anymore. |

Get a "Forming" tap, it doesn't cut. You will be okay. |
