- Watch Bryan put together a spicer ds 404. This video just kind of highlights the assembly process of these units. For those that don’t know this is a differential out of a semi truck. This particular differential came out of a 379 Peterbuilt. As with tradition this repair is done in house @etrtruckcenterenginedrivet8918
Thank you very much for watching.
Have a great day!
Coming from someone who used to work at a wrecking yard, this is a good honest person and should be ever so fortunate to buy parts from.
You sir are a dying breed, we need this knowledge passion and detailed message through your hard work
Love watching a professional share his wisdom. They possess volumes of information that most don't fully appreciate. Thanks for sharing with us! God bless!
Great video.
Thank you for the post. Sub and check out our ten speed rebuild tutorial
Amazing video thank you ! Please teach new folks so your knowledge will live in generations
That finger snap cracked me up 😅
Much appreciated sir
Thank you for your knowledge and teaching us, the little guys how to
Love the clear and straight forward NO BS tutorial
I like how this guy make easy this job. Knowlege is the trikky. Thankyou. MASTER.
Great job, years of experience!!
Very good I love that.❤
Nice video. The audio is difficult to hear . This man has obviously built lots of these. I've changed alot of these units but never went any further than the power divider. Glad to see the rest of it.
Thanks for the feedback we will try to talk louder in the next videos. Do you think these videos need to be more descriptive or are they good just seeing how they go together?
@@etrtruckcenterenginedrivet8918 Some description is great. I'm not a fan of the people that drone on and on. It's the important details that i like. Or the trade tricks. Again great video. 👍
Thank you for the feedback sir
I really enjoyed this video, ive only redone maybe 3 or 4 diffs ,so the little tips and tricks help. Ill keep them in mind on the next one i do. I thought i was the only one that called anaerobic gasket maker grape jelly lol. Man i love that stuff.
Haha yessir the ole red jelly is awesome stuff. Glad the video helps and thanks for watching man.
Good ole boys making It happen. I like you guys, 2nd video in and I’m hooked. I do have to say it blows my mind that your showing pride, expertise, skill and a way of life and got 2000 views. Then on the other hand some soft Fanny bandit sings a song blows all his money on tattoos and drugs, uses women and makes millions. Things are so upside down today, but you boys give me hope.
Thanks for the kind comment Jay glad you enjoyed the videos and if you ever have to build any of these units we hope it helps
Far out man good vid 👌. Interesting
Glad you enjoyed
Thank you!
Thank you for watching Killn
Thanks. I learned a lot.
Glad it was helpful! Thanks for watching Vaughn
@@etrtruckcenterenginedrivet8918 I am getting up early to replace the O rings on the power divider lock out. Thanks to your video, I know how to do it.
Awesome video… I subscribed…
Thanks and welcome
Thank you sir! Question: if you wanted to, could you have changed your gear ratio while you're there? Or, is it true that your truck, being a 6x4, would require the back axle be taken off and that whole ratio change be done on that one, too?
Yes sir you have to change the ring gear and pinion on both differentials to swap gear ratios. If you only change one you’re gonna make big problems with both diffs really quick.
@@etrtruckcenterenginedrivet8918 thank you
One of our trucks international with old n400 with one locker with 3.91 gears front drive had me puzzled never seen this before as it was going down the road was smoking driver side front drive tires thought it was a brake issue but was not the case could you explain that to me please looks like it broke something in the differential itself as in the sand it was turning different rotation than the rear
WOOF!
Job like this how much would this cost to rebuild
How do you pull the bearings out? And what tools number?
What does it cost to swap gears in a Dyno max MH chassis ?
I REALLY LOVE YOUR VIDEO， MAY I BE TRAINED WITH YOU。。。 I REALLY WANT TO DO HEAVY DUTY MACHENICS。
If the pinion bearing preload is so loose that you have to hold it with a pry bar to check backlash and drag it by hand to squeeze out pattern grease, then it is to loose. Preload is critical to the life of the unit. Also double check the ring gear runout by putting dial indicator on smooth back surface of ring gear, turn. Max allowed is .008" on the 404 if too much runout, unbolt diff cases, rotate 180° reassemble. It's a quality of manufacturing issue. Most good mechanics can build a rear that works but industry experience builds a better unit
ring gear doesnt warp, case halves do. you check runout on the case halves before the ring gear even gets installed if you want to do it properly. If you're not doing this style of pre load on a 40k, your loads are too tight.
@@AC-mf8ou wrong, run-out is checked after the ring gear bolts are tightened when gear and case are pulled together. You can check the case for trueness before that to avoid assembling a uneven case if you want. And what you have there is actually no preload. Preload technically can be measured with a torque wrench and socket on the pinion nut. Measurement is in inch pounds required to turn bearings. You have no preload obviously
@@captainaxle438 Yup, and its not technically, thats how you would measure preload. As for the case halves, you're measuring the part that never changes, you are wasting your time. Measure the case half only.
@@AC-mf8ou Sonny, case halves change plenty. They get warped and bent and they crack at the base from broken ring gear, bearings come apart, massive failure. They even flex during shock loads. Some models have an adjustable thrust screw in the case that is set .020 in to back of ring gear at pinion location to stop the deflection of the case during shock load. Checking run out with ring gear bolted to case is the gives the final result of what run-out is there. You have no comprehension of the power and weight involved in transmitting 1800lbs of torque to move 80,000 lbs of truck. An overloaded dump truck makes a turn onto an on ramp and leaves pieces of rubber on the road. As far as measuring preload it is the technical way to use a torque wrench because most all preloads are checked by feel. A light duty dana 60 average pinion preload is 28 inch lbs. Heavy truck is set much higher. And a free spinning bearing has no preload, duh as in this video
You do great reading the service manual. You're rambling. Get help
You rebuild two speed rears?
Bryan does yes
I subscribed neat shit going here.
Thanks for the comments Dennis and thanks for the sub!
