I have been looking in all my T books and searching the Forum for a diagram that I have seen about wiring the ball cap bottom bolts. Size of wire and method. I just replaced the hogshead, and am putting everything back on a 25. Assistance is appreciated. Thank you.
Here is a scan of Figure 32 from the Ford service manual showing the ball cap wire. I have a spool of 0.041 inch stainless safety wire that I use for all of locations that need safety wire. I also bought a cheap pair of the special pliers on ebay. They aren't really necessary, but they do make the job quicker and neater looking.
You probably already know this, but you want to arrange the wire so that it pulls on each bolt head in the tightening (clockwise) direction.
The wiring job shown in the diagram above would probably not pass muster in a safety wire class.
Here is an example of a better job:
Thanks for the prompt response.
Size of wire and method of winding is absolutely critical to a safe running T. :^)
What size and type do you recommend? Thanks.
Kidding aside, its only important that the bolts not come loose. Fords method is fine, Mark's is better. I purchased some aircraft quality stainless steel locking wire .032" and .040" thick which I use for about everything on a T that needs it. I think Aircraft Spruce carries it. I've seen baling wire, lock washers under the heads, etc, anything that works is fine.
Here is a short slide show presentation on good safety wire technique:
You only need safety wire on the bottom two bolts. Cotter pins are fine for the top two.
