10,000hp BIG BLACK REAR END assembling Part 1

Step behind the scenes to witness the assembling of a 10,000 hp Chrisman rear end. This video is the detailed assembly of the spindles and drive axle of this 12 inch ring and pinion monster rear end! These rear ends are used in NHRA topfuel directors and funny cars. If you are a mechanical person or just a drag racing fan this video is for you. Follow along with this series as I explained the workings on a $20,000 big black rear end!

I noticed the old, proudly made in USA ratchet by Craftsman. No doubt about it, you have been at this gig for a while.

@@robwendland I still have some of my Craftsman tools from 1967, almost as old as you. I beat the junk tools, not the classic aged ones.

Awesome video it's about time someone show's us gear heads how the big boy's do it thanks

[@ratmousebastard]

wow... this is just an incredible amount of information... and Rob your teaching skills are as good as any of your skills. This is such a fantastic video (as are the other in-depth videos you've done), I've never seen anyone go into this depth about anything fuel car related, it's always just hacked down teasers... but this is the real deal. I'm not dead yet but I'm old enough to have a ton of life's regrets, like never working on (or driving) a nitro car, but watching videos like this is a real treat and I don't feel quite as bad (still wanna do it... hey, if you need free help I'm your guy! I weld, wrench, fabricate... but no way near this level of wow). Thanks! Of course now you made me feel wholly inadequate with my little 9" with tiny 40 spline axles (man, I can't believe how big that axle is... and one piece too! What is the size/spline on that monster???)

[@Darnic-Fab]

Very well done!

Love the detailed content, Rob.

[@robwendland]

Thank you brother! Thanks for watching!

[@kennethbode2017]

most of the big rigs use a similar spacer between the bearings and you torque the nut that holds it all in. Nice design the way the cap actually drives the wheels

[@kh40yr]

Amazing that a Parallel ground washer isn't required to clamp the spindle ends down. Sounds like it is just a standard-ish-ARP-$$$ "stamped/punched" bolt washer with a punch rounded side and a flat side. Not bitching or complaining,, just curious and interesting. ALWAYS face the flat side to the work piece on a punched washer. Thanks for the Video's Rob. More please. Big luck this season. Go snag another US Nats golf check.

[@robwendland]

Right on brother!

hey Rob, look into Silicon remover by Motorcraft, its made for the 7.3 diesel gaskets which are really high quality silicon and stronger than normal. the Silicon remover takes it right off, AND smells like Pinesol while doing it, and easy on your hands. thanks for the awsome videos, love seeing this top fuel stuff and holy shit those tolerences when u put the axle in... damn!

Wow hard to believe that that giant axel is driving an aluminum hub that puts all that power to the ground amazing. Lots of splines is the key i guess. My uncle had a fuel car for a couple years but i never really checked out the rear

@@robwendland You are very welcome! Drag racing absolutely needs more channels (and people in general) like yourself! Hell, whenever I end up applying for a nitro gig again, lol (I know I will again, lol) I'll have to find you guys at a race, you would definitely be an awesome guy to work with and learn from! It's a lifestyle of hard work... BUT the never-ending learning makes it worth it :) Anyway, I share these with as many people as I can, whether they care or not is irrelevant...because they will end up liking it when I drag them to the starting line of any car runnng nitro. haha 😊🤘🏻🤙🏼

[@bobroberts2371]

Something to think about with silicone on the mounting brackets / spindle rather than an o ring. Silicone will reduce the chances of fretting between the two parts and the resulting loss / reduction of bolt clamping force since the parts are glued together.

I've been building 40,000lb and up rear assemblies for years. I'm surprised you didn't prefill hub rather than wait for the ring gear to lube it.

It films the hub to center section level in about 3 minutes. There’s at least a .25” all the way around to axle to get to the hub.

Is the reason for rtv is because it moves a little bit and rtv will flex a bit.wouldnt a oring just leak if it oblongs

[@chadferris5553]

Seems to me that if you only grind the edge against the hub on those flange nuts it would be better than going through the whole lathe process and it will hold the nut from spinning🤷‍♂️

[@robwendland]

What really needs to happen is the hub needs touched off with an end mill so it accepts a full nut. Should be done from the manufacture when he built the hub....
