Not true. The pinion spacer pushes the bearings apart, not together... so you don't crush them while torqueing the pinion nut. If you were to magically remove the pinion spacer after torque, the pre-load would sky-rocket and the pinion would seize.

@Supershafts2 жыл бұрын
It takes nearly 300ft to crush the collar , around the same would be the torque spec for them. Better off counting how many times to take the nut off and return it the same way , the torque required to crush or to be utilized for that size nut and thread will burn the bearings up in minutes. This is very much like a hub bearing , if you remember or know how they were like before unit hubs , you needed to have the correct drag , too much they burnt up, to little they got hammered to shit. Same applies for pinion bearings, except they see much greater force . And that's why you need to know what the preload is and that it is set correclty.

@Supershafts6 ай бұрын
The purpose is to retain the preload and hold the inner races in place and since there is constant noise from the ring and pinion , that torque is needed to prevent it from loosening over time. I once lost preload at Englishtown raceway from playing with set ups and very light preloads looking to see if we could find free speed and time. I also found out that day loctite has a shelf life, and no longer buy the big huge bottles anymore. So we lost the preload and the nut nearly came off between leaving E-town and getting back to home shop, which was a 100 mile trip using 2 feet to keep the pinion underload and not get sucked into the ring gear , so we know , I know first hand that in drag racing and other forms where it isn't seeing hours , you can run the lightest non existent preload , and also know that if you keep load on the pinion the front bearing can literally fall out, when we got back to the shop the nut was caught between the end yoke and the u-joint in the shaft , the end yoke was backed off and we were lucky we didn't lose the shaft as it could have dropped off the pinion gear. The front bearing wasn't stabilizing anything, when I had to slow , I had to keep the engine putting pressure on the diff to keep the pinion planted against the main bearing so it didn't get eaten by the ring. Was a part of a experiment I wasn't looking to learn that day. This was back in 1988 or near that time. A new nut and reset the proper preload and new loctite fixed that issue. On a drag car only that nonexistent preload will work , but not on a car seeing street use, or atleast not one with expired loctite. So check your dates on your loctite guys and girls, if it's past the date, lose it , don't use it.

If you have play in it , you can try to give it a slight turn, but if the nut loosened up it's gonna again. Now if when you go to tighten it , 1. Tiny tiny increments of a turn , like 5 degrees and then drive it , see if the nosie went away , if it did, that nut lost its ability to hold... if it feels like you need 300ft lbs of force to make that 5 degrees of a turn, then something else is wrong. A bad carrier bearing can sound similar on coast and usually the left side that'll make that noise. If you have movement at the pinion up and down or in and out , either the nut gave up or a bearing is done. To check that get the rear off the floor . .

Interesting stuff. I agree completely. Especially on the political stuff. But on 60's Fords all 8" and 9" rears got crush sleeves EXCEPT the hi performance vehicles. Every Boss 302/429, 427 and 428 cobra jet car from 67 on got a nodular iron case, Daytona pinion support & a solid spacer. Why do you think Ford would have used them?? Their engineers definitely knew more than just about anyone out there at the time and it would have cost more to do so. What's your thoughts on that?
@Supershafts2 жыл бұрын
There is no way for a CC to cause a issue. The only thing they might have wanted was a reuse issue. Definitely it serves no purpose in strength or longevity. . The only way to make it tighter is to push the end yoke and have something push the pinion gear at the same time, that can't happen when it's in use. The only thing taking place is the loss of preload by wear from use or lack of oil and abuse. If Ford was smart they would have trashed that horrendous design ... But!! They didn't , so makes me think they weren't really paying attention, when you compromise something for another idea , it's a bad idea. Losing the space in the carrier for the much needed 3rd bearing to support all that pressure and drag to compensate for more tooth contact was a great mistake.
@evancloninger3906 Жыл бұрын
It's easier to install a set of pinion bearings with a crush sleeve on an assembly line, in fact, automated machinery can accomplish the task. In order to reach the correct pre-load (drag) and, concurrently, the correct nut pinion torque with a solid spacer, you'll have to take it apart several times and add shims.

@Supershafts3 жыл бұрын
You can replace a seal if you're very careful and leave the current CC in place. 1. You need to mark the socket to the end yoke and count every turn and where it finally came off as if it was a clock and the time, , when replacing it you go back the same EXACT turns you removed it, but you use a new nut and red locktite. When (just using this number as an example) you get back to the 29 full turns and 3 o'clock position, so if we were looking at this as a degree,, 3 o'clock would be 90 degrees , now you go another 10 degrees and that's it , done, nothing more. Put the tools away and top it off . I've done this on my own shop truck and many other vehicles, with no negative effects at all....however other shops have done this and got me a few bearing jobs from over tightening it or just not having any clue what was going on.

Great video! Love your commentary! The 12 bolt posi gear set in my '68 el Camino seems to be louder than normal to me. I wasn't the one who set it up, but I am a mechanic. If I were to take it apart to check the current pinion bearing preload and found it to be I don't know, let's say around 7 to 10 in lbs or so, can I just snug it up to 15 to 20 in lbs to see if it quiets it down? The gear set has around 2,200 miles on it. Or should I remove the pinion and start over? I have the axels out already and am ready to remove the carrier. I do have a complete understanding of the entire process, so no worries there. Just wasn't sure if I could just snug the nut up some, maybe that would destroy the effectiveness of the loctite though. The installation instruction sheet calls for 15 to 25 in lbs rotating torque on the pinion nut when setting up new.

Well I like to stay between 16 and 24, when the bearings finally get run in it'll loosen up and have less drag. Now nice and quiet means your gears are together right Doesn't mean you don't have too much preload and you're burning up your bearings , so when you do the oil change if the oil is ANY where near black, you're too tight, or you got way to dopey doing your breakin, It should be light to med gold color. Now if it's in the brown range, you may get away with preload. But breakin also plays a role in oil temps. Remember don't try and pull anything the first day , don't be showing everyone how much faster it is with the new gears either. What I do is Two 15 minutes runs. Basically, normal runs. No foot to the floor dead stop starts, but roll in up to 60, 70 depending on ratio. Let it cost down a bit. Drive for 15. Let it sit completely cool off and do it again for another 15, after that i instruct my customers. No world record sled pulling and no land world speed record setting for the next 100 miles. Mistakes many people make are this... ""I did 100 mph when I drove my car off the lot""... yeah and your brand new car had its trans, engine, and diff run in at their specific companies of origin , so technically, you didn't do any breakin procedures. But also , remember don't look at breakaway drag , we don't care about breakaway. We want to see consistent motion load. I'll do a video of what and how that is done. I don't think any of my current vids really touched that.
