- In this video I am going to show you the first step necessary to make your AMC/Jeep Model 20 rear axle bullet proof. First step is to get rid of that troublesome crush sleeve or crush collar as it is often called. A shim setup is the best way to set pinion preload and I will show you how in this video.
Once I get the pinion bearing preload set properly I will install the ring carrier loaded with a lock and ring gear. A few shim adjustments on the carrier bearings and the backlash falls into place perfectly. A quick look at the tooth contact pattern and the rear axle is set up properly.
One last time it will be disassembled and the set up cup and bearing will be replaced with the new parts that I have ready to go.
You make it look so easy! I hope my goes well when I attack it
Take your time and follow my videos and you will have a great axle.
All right! Looking good Brian, pattern looks perfect. Thank you for the update. Great job.
good morning Scott. The model 20 is coming out great and doing my best to make it super sturdy for a lifetime of use.
Thank you Brian. Happy new year.
appreciate you watching, enjoy the new year.
Brian and family... Happy New Year 2023. Juan
Good to hear from you Juan, all the best for the new year to you and your family as well.
Thanks Brian, another great video. Happy New Year!
appreciate you watching, enjoy the new year, let's hope it is a good one.
Another good video Brian, I plan on rebuilding my entire drive line this year. I will be referring to all of your videos. Thank you for all of the information.
Always good to watch and learn correct set up. Hoping to so wrap up many loose ends and get onto my Dana 27 rear axle. Will have to revisit this and your other videos when that time comes. Again, best to you and Maria in 2023, Bear.
Always educational and well explained, thank you Brian for taking the time to do this and happy new year.
Cheers from Canada
glad to have you watching from Canada.
Thank you for another great video Brian! Like you said, you've put quite some good information out there for the Dana 25 and Dana 44 and thanks to you, I've rebuild several with success! They do take some patience, but it is sure rewarding in the end. Looking forward to more videos of the AMC 20 and the Dana 30!
glad you were able to get some axles built. Appreciate you watching.
Another timely video for me, thanks again.
Glad you enjoyed it!
Brian, can you link me to the crush sleeve eliminator? Having a hard time finding one. Thanks
What shim eliminator kit did you use? I’m not seeing one for the AMC 20. Is that a Yukon ford 9” crush eliminator?
Hi Brian I'm rebuilding a 1984 cj7 and I'm rebuilding the AMC 20 I'm keeping the original gears 2.73 since it will be on the street only. I'm replacing all of the bearings and I'm going to add a crush sleeve eliminator . What should I do first , figure the shim size for the pinion depth or the amount of shims for the rotational torque? Thank you and your videos are extremely helpful !!!
If you are keeping your original gears then start with the factory pinion depth shim. Next get your rotational torque figured out with your crush sleeve eliminator kit. Once you have all of that figured out you can get your carrier shimmed properly and check backlash.
@@metalshaperJeep Thank you!! Your videos are excellent. I'm doing a frame off restoration and your videos are such a tremendous help.
Hi Brian it seems the rotational torque is too tight even with no shims in the eliminator when the pinon nut is torqued to 175. I used a pinion depth shim size that was very close to the original but even with no shims in the crush sleeve eliminator when I torque the pinion nut to 175 I can't even turn the yoke. Should I torque the pinion nut to a value less than 175 ? Thank you.
Never mind I finally figured out that I need to add shims. :)
Brian during final assembly do I have to tighten the pinion nut more than 175 foot pounds to set the pinion bearing (smaller bearing) ? Or do I just torque the pinion nut to 175 and that is enough to set the bearing. on the pinion shaft? . Thank you.
