Then before you take the car out for the first time look at every nut and bolt.
If there is no paint on the bolt/nut/joining device then you need to fix it.
This method works for any connection even AN oil and fuel lines.
After all connections have a paint mark then you can drive the car for the first installation lap of your test area.
Now I know that a lot of you will think that you do not wish little spots of paint on all of your pretty grade 8 bolts and in particular not on your gleaming ARP bolts that you spent too much on.
Believe me, it is better to have the paint on the connection then it is to have the left front upper A-arm fall off. Or Lower for that matter.
Every A&P mechanic I know uses this method as self QC.
Also next time you are looking at an F1 car notice the little yellow marks on every connection. You will see these marks on the inside of the engines as well. |
+100..........been doing this for years, I also use some of my daughters finger nail polish in contrasting color to mark stuff along with a Sharpie......that way I know it has been torqued/tightened down....when building something over time, it's easy to forget what you have tightened and need to tighten...one quick look and you know.....
Again +100...........
