Tried to install my new Hi-flow bolts and fuel pressure guage. Ran into a big problem. I was installing the first bolt, just happens to be the bolt for fuel into the VP44. I was putting the tapped fitting there. I was tightening it down when it sheared. I was like this guy --> . I was able to get what was left in the VP44 out by hand. Put the old one back in, and now this project went on the shelf while I get a new tapped Hi-flow bolt and two more sets of those bolt gaskets. So be careful when tightening these things, these bolts are very delicate.

 

A torque wrench is your friend.

Torque Spec for the Banjo Bolts
24Nm or 18 ft. lbs. (216 inch lbs if yours like mine doesn't read that low)
Save the 400 pound Gorilla for the lug nuts.

 

Homer Simpson says DOH!

 

Torque wrench was used and set for 18 lbs. The torque wrench (clicker type) never clicked.

 

I've done the same thing. I had to overnite a banjo from Geno's cuz I was on my way outta town the following day. $25 later for 1 bolt, I was on my way. Now I make sure that I don't over tighten'em.

 

Time to get a new torque wrench.
I've found it much easier to use my inch pound wrench on light duty stuff.

 

its hard to torque any thing with crush washers. just install them hand tight and then snug down with a wrench. I do banjos on a daily basis with only one shear...ever...knock on wood

 

I went hand tight and then half a turn past that. If it leaked, I let it run while I gradually tightened it till it quit.

 

Jim and Big Blue, thats what I'll do when the project resumes. I was very suprised how it just sheared, like it took very little effort.

 

It's interesting you say they sheared so easily. I've cranked mine down so hard I broke the washer and the bolt didn't break.

 

Could have been a hairline crack in the old one.

 

I had a FASS Fitting do that....0nly one since then.....i agree, might have had a hairline crack or milled a little too thin. The others seems like you have to crank down on to stop them from leaking...and i know i used way less torque to pop the other....i felt your pain....mentally and finically!!!!!

 

Mentally I was like oh crap . Financially I am only out 9 bucks. The old one was not cracked that I could tell. I now have serious doubts about my torque wrench, I set it to 2 pounds, put a deep socket on it. I grabbed the socket and tries to turn the torque wrench, the wrench still never clicked.

 

Just a reference. You can only apply about 30 inch-lbs on a std. size screwdriver handle. Unless you REALLY reef on it or you are a gorilla.

I worked for a torque tool company for 10 years. We had torque screwdrivers with slightly oversize handles and had contests...I don't think anyone ever hit 40 inch-lbs.

 

My max-flow fittings are plenty stout and for sure won't shear
