Irie's axle test

[Sr.Irie]

In the spirit of full disclosure this is what I have done.
I purchase Vaterra front axles, then I strip them completely apart including pressing the cross pin in the dog bone out. I then take them to a guy who does metallurgy and he does a tempering process to them. When I get the axles back I press in a new dog bone pin that I had made from 4037 chromoly. Then all parts in the CVD end are polished to a mirror like finish for smother operation. Lastly I reassemble the axle using a cross pin I have had made out of, again 4037 chromoly and then lube with Lube Con molybdenum disulfide. This is basically the same process I used to do to 930 joints in 1:1 rigs with great results.

Here is a picture of the axles just before reassembly


Here is a picture of the wear to the chromoly CVD pin compared to the stock pin from the axles that I have been running. I was running a stock axle in one side and my race prepped axle in the other. So both pins have been through the same use and abuse, in theory.

Love it lol u sir are gonna break my bank account I gotta lot to order...after testing of course

[MacJamez]

Looks promising. Keep us informed on them and when they will be for sale. Just broke the pin on another axle.

Wow, I am impressed and looking forward to you releasing these.

I have only broken one, I run a open diff with thick oil though. Mine are getting very sloppy!

Keep up the good work and thanks for showing the Twin Hammers some love!!

Nice! Do they run smoother at extreme angles?

Yes they do here is a short video of them lock to lock. Pay no attention to the poor video quality I need to upgrade my video capabilities.

Well done sir, hats off to you

Awesome. I'm in for sure. have you considered doing them on an exchange basis? I have a brand new pair waiting!

No but that is a good Idea

[Erin]

So is it a heat tempering process or cryo stress relief he is doing to shafts? Or both?

Im assuming you are doing both shaft and axle cup.

[ROLANDROCKSHOP]

very nice!

Im running 3s on mine and have yet to break a cvd..still on factory piece.
2 U4RC races..3 terrax races on them.

But when I do ill for sure grab a few from ya!

It is cryo and yes all parts are done.
Also my guy says if this dose not work there are other things we can try with heat.
The man has been doing metallurgy for the mills around here for many, many years. I have taken other odd projects to him in the past and he has never steered me wrong.

I was hoping it was cryo'd

Any idea on price point, either supplied or customer supplied? Not sure if you started a vendor thread or not yet. You could pm me also. thx

[Sr.Irie]

I do not have a price yet as I got the two sets cryo'd for free to try and see if it will work. So I am not sure what he will charge yet.

I do have a thread, Irie Products there is a link to it in my signature line.
Also here it is
Twin Hammer parts that smoke the competition

[SkaldidDog]

Another option. I use McMaster hardened steel pin guages (cut down of course) in all of my rigs as cross pins. This allows one to step up the OD by 0.0001" increments to eliminate slop as the holes in the barrel and cup expand with wear. Each time I replace (annually), the pin gets bigger and tougher. No point in using the same pin OD if the holes are all bigger. The barrel hole is always limiting for obvious reasons. Not sure how the McM alloy stacks up to this one though.

I had these pins made for me and they are just a hair bigger dia. than stock. The stock ones I felt had to much play. That is a good idea. If this all works out I may have some, for no better term rebuild pins made also.

Just a small increase in OD means lots more area - that's good

[Sr.Irie]

A little update from my side of things.
I have run 17 batteries through my truck with me and my 4 year old at the wheel. He is probably harder on it than me, he loves doing back flips and stopies.
No breakage and no major play, so far so good!

Wheelbyte will probably be chiming in soon with his thoughts.

Hopefully If these work out it will not break the bank because you will only have to buy one set or at very least not go through as many sets.

Thank you but put your hat back on lets go wheel-N

[Smurf]

Can I buy a set of test axles?

[Sr.Irie]

No because I only have or better yet had two sets one is in my truck and the other is in Wheelbyte's. Until I am sure I am not going to change something, I am not doing any more. I do not believe R&D should be a customers responsibility and when I make a run of these I need to do a few not just one or two.

I will put you or any others on a list of people to contact when they are ready. So if you or anyone else would like to be contacted when done please PM me, then I can keep track.
