Anyone know the JDA custom boys personally

[High-Gain Busa]

I purchased some 40mm risers for the front of the Busa from these guys. Should have been a very easy install. Put them in, slipped over the washers and spun on the supplied nuts by hand, tried tightning with an air ratchet. All nuts went part way up and seized at least a full half inch from even tightening. The threads that they passed became razor sharp indicating a mis-match in machining more than a thread pitch mis-match.

I was lucky enough that I have quality allen sockets and could snap them off by trying to back them off. I had visions of bringing out the die-grinder with a cut off disc.

I sent JDA the same pic here and they told me I over torqued them and would have to pay for new bolts and pay for shipping. OVER TORQUED!, they were 10 threads from even touching the washers yet.

I have also tried calling 3 times choosing different extensions including sales. Eternal hold and the music wasn't even good

Overtorqued.... I am still laughing

Did you actually mentioned you used an air ratchet?

If so, this may have planted the "overtorqued" idea into their minds.....

Never heard of them, but how about a letter with an explanation and that picture?

 

[Warchild]

And did you examine the hardware to be absolutely, positively sure one isn't standard, the other metric?

That would be pretty lame of them to send you mis-matched threads, but, ya never know....

Absolutely... A 3/8 air ratchet. My 10 year old daughter can tighten more than that. Beats twisting an allen wrench for an hour. Imagine the torque I had to use to reverse snap them? I had sickening visions of digging out the cutoff wheel. When they seized, the triple clamp would still rock back and forth... Must have been close to a half inch of threads left on all bolts.

I sent them the same pic and letter yesterday. They replied it was my fault the nuts seized and I would have to pay for new bolts and shipping. Said I over torqued them... The nuts had half an inch of threads left when they seized. How do you over torque a nut that hasn't even mated yet? They started to get tight before the nylon started to reach the threads and my first thought was that is some serous nylon up until they stopped.

PayPal is taking care of this one. Their e-bay feedback was not good and I should have known then.

Live and learn

Dont know JDA and I'm not taking sides on your misfortune. What I have noticed in the past is when you use Stainless Steel Bolts with Stainless Steel nylon insert nuts,using a high speed air ratchet,this creates alot of heat on the threads and causes them to "gall" and sieze up.Eventually busting the bolt off.I have had this happen even before I got the nut tightened down. I always use non-air tools on stainless/stainless fasteners & my problen went away

exactly what we ran into on my drag boat.. (Everything is stainless)and impacts/air ratchets would gall very easily.. not sure but may have something to do with the high nickel/low carbon content.. A one time application of anti-seize seems to leave enough aluminum in the groves to stop the problem..

If you have a Fastnal shop around you they keep the new stuff in stock you need..


Also on the riser kits, mine do not bottom out on the bolt. The bottom on the spacers and collars..

I could agree but the air ratchet is only 150 RPM free speed, not what I would call high speed considering that's only about 2 turns a second and if you look at the pic, the nuts barely made it up the bolt before siezing.

The portion of the bolt the nut made it past cut the threads to a razor sharp edge.

Should have bought from me.. I would have already had new bolts in the mail for you.

Although my bolts are NOT stainless steal.. link below.. LMK if I can make it right for you..

[Mr Bogus]

here is the tell: look at the first threads.. they are in good shape..

another fix we used was to "wire wheel" ALL NEW BOLTS... you have not seen trouble till you are between rounds and a bolt breaks off in the stringer of a 250lb hydro hull.. you can not exactly "beat" them out without damaging the hull..

i also didnt recieve very good customer service from JDA on my chainguard-orderd a custom one n waited a month...got no word, called n they said one week goin to the machine-shop...okay, one week goes by-call back again??? they said the exact same thing. I said, please cancel my order...I had orderd at the same time as a +4 Belly wing n the wing shipd one one week?? dont get it-mebbe they're bi-polar in the order-placing dept...

We sell & install the Pingel brand risers at our shop.I personally had this same situation occur to me with the pingel ones (with the customer peering over my shoulder).I ended up snapping off the bolts after seizing them while trying to install them with a little/slow 1/4 drive air ratchet.Had to use a huge breakover bar for leverage to finally bust them off.went & pulled another set of risers off the wall & robbed the new bolts out of it and installed them using a hand powered wratchet and whallah! no more galled threads. I'm just trying to help

The bolts are stainless, the nuts were not.

It would have cost them $29.00 total to take care of the problem... That includes shipping and is sureley not their cost.

Instead, blame the customer, loose a customer.

This pic shows how far the nuts made it before seizing to the bolt.
Supplier says I "over torqued" them. Kind of hard to over torque them when they don't even make it to the washer.

 

[Mr Bogus]

As posted above by Smithers and what I have had to deal with on boats.. Stainless galls and self destructs unless you go to some preventive measures... you can go get 4 more and they will do the same thing with power tools unless you polish the threads (wire wheel) or use anti seize.. Otherwise run them down by hand..

 

[High-Gain Busa]

I appreciate the input but in 25 years with GM, I have threaded a few nuts.

Bolts were stainless. Nuts are nickel coated steel... They can be picked up easily with a magnet.
The 2 I did not install cannot be run any further with hand wrenches; in fact I can barely get them to reach the nylon. There is a serious interference here.

They wont get my business, ever.

Had a problem with one of there custom chain guards.
Got it and the holes wouldn't line up right. Emailed them and they said that I didn't know how to install a chain guard and was doing it wrong.

I pretty much had to bend it over into place to make it work.

 

[roadthing]

You obviously know what you are doing, but an air ratchet? That's just asking for trouble.

Sorry you are getting a run-around from a vendor. Better luck with your next install.

 

[fastnotch2002]

never had any problems with them...ordered a few things...recently a custom chainguard/platemount for my Velocity swingarm....they had to custom make it...had it in a week and it fit GREAT! Never had anyproblems with them...when I called they were polite and helped me out for what I wanted.
