Author Topic: UCA shaft nut locking idea (Read 656 times)

Jonk67 · « **on:** September, 29, 2009, 07:29:31 AM »

Hi all, well I really wanted ORP's street UCA with the welded tabs but for budget had to go with the standard stock kit. I had my wheel off and noticed that my shaft nuts had turned (I marked them at install for reference). While I've got them loose for fenderwell painting I decided to drill a hole and tap for a screw (10-24). I then put the screw in and locked it with a nylok nut.
I'm just trying to keep the nut from turning, I think it just happens due to vibration/twisting which allows the nut to turn, I don't think there is a lot of force turning the nut so I hope that this small screw will stop it from turning. I don't think I could go any bigger as there isn't much of a shelf to drill through.
Will it hold? bend, snap?

Thanks, Jon

That is a hell of a good :ide ... Brilliant

I would bet that is plenty to hold the nut in place and make it way easier to replace the shaft kit when it needs it.

Thanks John, I was hoping you'd chime in. I'm correct in guessing that there should be no 'torque' applied by the nut during normal or even aggressive driving, that it just 'works it's way loose' because it can turn.
I have never welded and don't have the equipment so I look for solutions that I can do with my available tools and limited brain power....I can drill and tap!

Thanks for the quick shipment on my LCA eccentric kit, putting them on this week along with your roller perches. I can't wait to test all this when I get my motor back in. As stated when these wear out I'll be looking to upgrade to your street UCA (rollers if I can afford) and LCA rollers. I may PM you to see what it would cost to send you my stock lowers ('67) to be converted to rollers as I'm not happy with the repops I have (rubbing on L and R mount) and I have made my own adj. strut rods with '67 parts so I want to keep '67 lowers and not convert to '68.
Thanks, Jon

Excellent idea there Jon :toot :toot I've only had one of mine come loose once, but since I check them before each track event I didn't feel the need to fix. That's an easy enough fix that I'll do that next time I have it apart.

Great idea Jon. :toot It is also good timing for me. I plan on putting new uca in on my 66 and I don't have a very good budget right now due to the wife being layed off in May. I will take my old arms off and take them apart to see if the treads are decent enough to just rebuild them. Thanks for posting your idea.

Sometimes a simple approach is all that's needed. Just goes to show that you don't always need expensive tools and parts to solve a problem

Nice work, Jon!

I believe this is considered Opentracking Opentracker and winning!

Naw ... from now on this'll be known as the "Jonk - keep your big nuts from moving around mod".

OK, this brings up a question I've wanted to ask.....why do some call it the "Shelby drop" and some the "Arning mod". I mean, I know they are two different people, but whats the back story behind it all?

AzPete · « **Reply #9 on:** September, 29, 2009, 02:03:13 PM »

Arning did it, Shelby copied it......that is what I have read. People don't know how to call it the correct name.

Jonk67 · « **Reply #10 on:** September, 29, 2009, 02:20:02 PM »

From the history I've read, Klaus Arning was the lead engineer and came up with the drop design for the Shelby version mustangs so Shelby got the name credit.

I like that, the wife will be seeing this post, as a matter of fact she had to buy a bigger purse!
I did a similar mod with my briefs years ago but won't go into that...
