The 2Loose '55 Chevy Gasser...... UPDATE: BUSTED DRIVESHAFT AT THE TRACK....

First trip to the track, busted the front u-joint and the tranny yoke. The yoke was one that came with the Doug Nash, the u-joints are 1350's, no grease zerk, the driveshaft itself is a chrome moly unit I had made up by Strange Engineering.

It looks like one of the u-joint bearing ears on the yoke had a flaw in it, and it was cracked, and it looks like that ear sheared off first, taking the two sides of the u-joint that were in the yoke off next. The front of the drive shaft has the bearings solidly in the ears, but the outside of the ears are so beat up I don't want to try to reuse them. I'm looking for another yoke, it's a pretty standard TH400 yoke, and looking to just put it back together with a new 1350 so I can put it back on the road.

In the meantime I'm shopping around for a new driveshaft. There's nobody here on this island I'd trust to cut off the front piece on the driveshaft and tig weld in a new one, and balance it accurately..... I'd have to send it off island to have that done, so am thinking I'll just keep this one for cruising for now, keep it around later and have a new one made up for racing....



Well, I finally got to find out how well this rig will tow! I have had this towbar forever, welded it up when I was in college for another race car I put together with a couple buddies back then, and have kept it all this time, using it here and there over the years...

Welded a set of tow tabs on the frame at the front of the car to fit the tow bar, and had taken the bar down to the track with me (just in case!!!), when I busted the driveshaft....

So called my wife and she came down to get me, the car towed home quite nicely behind our Jeep Liberty....



ORIGINAL POST:

The 2Loose '55 Chevy Gasser...... ADDING A LADDER BAR RESTRAINT.....

The NHRA rules require a restraint on the front of the ladder bars just in case the heim joint breaks.

Looked online and the Competition Engineering ladder bar setup has a steel loop on the front that captures the front mounting bolt if the heim joint does break.....

(LINK to Competion Engineering for more info on this product....)

As you can see in the photo below, my cross member goes through the inner plates for the ladder bar support and there is no room above the ladder bar heim joint to do this setup, so I had to come up with something else....

So I designed a pivoting, sliding link which will limit the front end of the ladder bars from coming completely loose, and still allow normal movement of the ladder bars, and adjustment for and aft when needed....

Fabricated these parts from 5/16" steel plate I had laying around, and used grade eight 5/8" bolts with nylock nuts to hold it all together....

Added a plate for the frame side of this assembly to beef that part up a bit....

Welded the frame and ladder bar parts in place, and added some paint....

And painted the links and added them. The bolts are tightened just enough to take out any slop, they are just loose enough on the pivot end and the slider end to get unimpeeded movement.

I know there will be more movement than the Comp. Engin. setup allows if there is a ladder bar failure, but if I need to I will add a heavy gage U-shaped steel strap around and under the front of the ladder bars just behind this setup, hanging from the frame, which will further limit any ladder bar movement in the event of failure.

More later, here's some links to other pages on this project site....
