Ford 9in Pass Through Axle Build Part 1 Building the Pinion

[@jacobbunyard8510]

Awesome! This is on my project list, looking forward to the next video.

Are we watching a genius at work because this is very well thought out.

@cmtfarms9777 I appreciate this comment very much, thank you!!!

I just want to call out the very end when that welded piece is spinning on the lathe so true and straight, maybe there could be more thorough welding for durability and longevity but holy cow did that come out on point

[@TooManyProjectsTooLittleTime]

@cyclesaviorn2700 that jig I designed/3d printed worked flawlessly. Very happy with that... yes the weld is definitely going to be the weak point. We will see in testing how it holds up!

[@cyclesaviorn2700]

@TooManyProjectsTooLittleTime heck i wouldnt be surprised if it never broke, the way the torque will be divided between the axles should take significant stress off of it

[@TooManyProjectsTooLittleTime]

@cyclesaviorn2700 Most people don't understand that. I'm so glad you said it! A lot of people seem to think it's the opposite for some reason as if adding another differential/drive wheels makes the power/stress 2x when it's the opposite.

Thank you for posting the video very helpful for a project i am working on.Welding for 37 years prep for welding. Would recommend full penetration weld.please post how it holds up.

[@TooManyProjectsTooLittleTime]

@johnayaso4095 thank you! Yes I know that is definitely the proper way to do it. We will see how she holds up! Part 2 should be coming soon 😁

[@christophermiller3123]

Purely speculation on my part but, to increase the strength of the joint, would it have been beneficial to thread the new shaft and pinion such that forward torque input would be applied to the threaded joint and not just the weld. Not sure on final application and input torque, just an observation I made while watching. Your video will certainly help me with my own project when I come to it. Great work!

[@TooManyProjectsTooLittleTime]

@christophermiller3123 AWESOME idea! Seriously this is why I post videos like this, not just to try and help others but to also open this sort of dialog from intelligent thinkers like you. I have good confidence this will hold up fine for the application I'm using it in but if it's applied to bigger heavier and stronger vehicles that's a very good idea. I did play with the idea of also doing splines, others also suggested this on the short I posted. We shall see how she holds up 👍

[@christophermiller3123]

@ I see now the plan is to go in something light. One would think as long as you have good weld penetration you should be fine. Like someone else commented the torque that weld will see will be half of what the transmission is outputting.

[@TooManyProjectsTooLittleTime]

@christophermiller3123 yes exactly, it's crazy how many people think for some reason the stress will be 2x more 😂. Funny how the people that say things like that always have an attitude as well.... I'm learning just like most other people on here, constructive comments are what help all of us build and innovate. The vehicle I'm building will be similar in weight to a UTV, slightly heavier but not as much as a full size pickup or SUV... maybe more like a jeep.

@@TooManyProjectsTooLittleTime How many axle variants did you look at before going with the 9”?

[@TooManyProjectsTooLittleTime]

@christophermiller3123 I looked around online a lot when I was just playing with the idea. I found several people that converted 9in axles because of the pinion location. Unfortunately I found absolutely ZERO technical information or build photos/videos. I only found very few low quality images of them completed. A good friend of mine has several ford 9in axles, one day I was over at his place looking at them and it all kind of clicked in my head. I bought one from him and started work on it. Not many other axles have the clearance from the pinion past the carrier/ring.

I want you to stretch my pinion shaft 😊

Typical YT comment section. I know it's far easier said than done sometimes, but hopefully you won't let the naysayers deprive us. I made a video under a different name, someone went through a tremendous amount of effort to insult some guy(me) on a no-name YT channel with few subs. If only they could put that much effort into literally anything else, like solving the same types of problems I was, and actually making sure the garbage they were spouting was true in practice (they didn't).

[@TooManyProjectsTooLittleTime]

@Sevalecan yeah it's definitely rough. The crazy thing is they think they LOOK smart in front of everyone. In reality, they look like absolute imbeciles. I would LOVE for these loudmouths to actually get out and turn some metal.
