Burn Outs Are Way Cooler With a Posi in the Tribute Trans Am - MuscleCar S3, E16

[@mr_paw_t]

wow! I just bought a late 70s firebird pro-mod drag car, rolling chassis two day's ago. I need to assemble so much! I must be crazy! uuuggggghhh

[@daledavies2334]

Posi, Traction Lock or limited slip does not do away with the spider gears. They are still there but spring force pushes the side gears apart against clutch packs. That has a tendency to cause both wheels to turn at the same rotational speed. Those clutches can slip given enough force, like cornering at more sedate speeds. There are specifications for different limited slip differential carriers to test the breakout force in lbft. This is measured with a torque wrench and one wheel on the ground and blocked, and the other in the air with the wheel removed to install a tool for the torque wrench.

Funny this episode came on today, I do have my first car. 1970 Oldsmobile F85, and currently restoring it. It's got A/C and a V8 auto. Rare car, not as rare as the W31, but still rare.

[@johnpena9165]

Nice 1970 Oldsmobile Cutlass W-31, one of the nicest Muscle cars made by Oldsmobile back in the day 👍 .

[@mr84ttop34]

Just had a posi installed in my 1984 Hurst Olds. So much better then the open differential.

[@looshin8r]

They're finally understanding modern terminology

[@drewp25831]

HOW EXACTLY DOES A POSITRAC REAREND ON A PLYMOUTH WORK, IT JUS DOES!!!! -JOE DIRTS DAD!!!

[@AaronCook83]

Posi: ties both the wheels together with a pinion. I'd love to hear your explanation of a torque converter.

[@AMERICANLEGENDModelBuilder]

😅😁🤪😜I had to see for myself, I guess I've been doing it wrong!

[@jeremymurphy7320]

It's JFM. Just F*cking Magic.

[@ncsteeltoe]

No kidding. That was pretty bad lol.

[@deancooper6300]

A torque convertor is the spinny thing filled with whatchamacallit...

[@paperweight57]

Camaro's get all the attention. Long live the Firebird!

[@otsenres1636]

That 73 Gran Torino Sport the olds owner was racing is badass!!

[@slowrunner1660]

Anodized red and blue -AN fittings 🤣🤣🤣 matches the decade of your sweet earing hoop! 🤭

[@shanepowers7566]

I guess they aren’t going to actually show us how a posi gear carrier works. I’m glad I already knew.

[@OriginalMomo]

Not even two minutes in the video and I already see a problem. Did you really not Loctite the ring bolts? With the amount of abuse that things going to get, you should’ve painted it red with Loctite…🤦🏼‍♂️🤦🏼‍♂️🤦🏼‍♂️

[@taskforce555]

don't it bother you that underside not even painted? they just assembling everything for mockup, everything will be disassembled a lot of times before it would run

[@bluegrassman3040]

Marco if it even does run...

[@bmstylee]

That is one nice Olds.

[@patrickharrand]

That '70 Cutlass (11:27) for $4,460.84 new would equal $29,477.64 today (2020) (for inquiring minds like mine.)

[@slowrunner1660]

Love the preload on the carrier bearings,. slam that thing in and out a few more times too, maybe that's a new thing..

[@richindiankid]

Haggerty has a much better installation video

[@2511jeremy]

Umm guys using a plate to press the carrier bearings doesn't work often the carrier pokes out a bit and your bearings are not all the way down

[@conover1978]

He didn’t go over the axle seals! That was one of the biggest problems I had on a 9” I build was keeping the fluid in the housing bearing seem to leak with no seals.

[@2511jeremy]

And the caps should be torqued then the back lash set it changes the setting alot

[@johnmilner7603]

LOL, I still kept my 70 Z28 when I had kids. Could never figure that one out. Just buy a 2nd cheap car.

[@bobbybanis2905]

Rick and his near mute partner are about as entertaining as watching paint dry.

[@otsenres1636]

Its better than lou and his loud pimp-my-ride talking! His near mute partner looks like a guy that sells "party favors" drives a shitbox civic and always has a black eye...

[@FranksShitBoxCollection]

Great way to start my day.

[@dinos0429]

I'm hoping you stick true to the Trans Am and make those hood scoopes functional.

[@taylorh3930]

Finally a nice fuel injected drivetrain and not some old carburetor piece of shit.

[@anthonym6078]

Nice car, but all that work to rebuild it and you put a 4l60 in it. I wouldn’t even waste my time with a 4l60e, especially with an LS7 in front of it, it’s basically guaranteed to be the first thing to break on that car. The 4l80 is better in basically every way, and it’s really not that much bigger than the 4l60, not sure why anyone bothers with the 60.

[@rammer561]

He did say it was ultra tough version from TCI that can handle 600 hp. That still not adequate?

[@BobbyOfEarth]

Funny how some people call the 350 Olds W-31 a small block, when the 455 Olds use the same engine block and heads. Drop an Olds 455 crank and rods into a 350 W-31 engine and you create a 455 torque monster.

[@maddpeanut7524]

While true of Pontiacs, Olds used two different blocks. The 455 had a taller deck height (casting # 396021) versus the 350 ( casting # 381917 and 395558). A small block measures 12" between the heads at the manifold base, a big block 14".

[@ducamuk]

That was way too easy. You need to show us what to do if backlash is out of specs. Or, perhaps, what to do when tooth contact is not correct on the ring gear. Still, great video. Thanks for posting.✌️

[@thetruth45ful]

It’s honestly just adding and removing shims to get into spec. To much backlash you need to remove shims. Too little and add shims. It’s not a complicated process. Just take your time and measure more than once

[@Richardsmithabcd]

Peg leg, I call it a one tire fire.

[@jeremymurphy7320]

My high school car, a '76 Monte Carlo, ain't coming back to me and I personally guarantee it. I watched that sucker get crushed the day I took it to the bone yard .

[@scootergeorge9576]

Anyone who does not know what a posi is, wouldn't be watching this.

[@edwardmyers1746]

"Or my personal favorite, weak" 😂😂😂

[@otsenres1636]

That rviet-nut tool is sweet.

[@maddpeanut7524]

Not really needed. Use a bolt with a washer and nut against the top of the rivnut. Hold the nut and tighten the bolt to squish the rivnut. EZ.

[@alwayzworkinalwayzearnin2427]

Anyone notice that there bolts for the rear shackles don't protrude far enough for the locknuts to actually do their job! And no antiseize, sucks to be the next guy.

[@hotrodray6802]

4:20 "inch pound torque wrench looking for 20 pounds" ?

[@nathandean1687]

freeze all parts of night and they will slide on by hand

[@FerasAlhawas]

5:25 i think open diff sends 50% of the torque to each wheel

[@lemmy8947]

Open diffs are 50 split, but they equalize the torque, so if one wheel is getting little to no torque, then so is the other

[@FerasAlhawas]

Lemmy how did he spin the wheel while the other wheel is not moving?

[@maddpeanut7524]

@@FerasAlhawas That is a trait of an open diff. A limited slip will turn both of them if you try to hold one still, assuming you can apply enough torque.

[@FerasAlhawas]

Madd Peanut oh , i though the open diff spins both wheels because the torque split, after doing researchthere is difference between whee torque and speed

[@maddpeanut7524]

@@FerasAlhawas Yeah, an open diff will send torque to both wheels until one loses traction. That's what you are simulating by holding on wheel still. The wheel that loses traction then received all the torque, hence a one wheel burnout. Limited slips continue to supply torque to both wheels usually by means of springs and clutches.

[@v.e.7236]

Have to say I've never slammed a carrier down into a diff like this guy did. Seems a bit brutish, but hey, these guys are experts, right? smh I certainly won't be changing my SOP for the job.

[@smashface3080]

Eww that patch for the oil reservoir is fugly

[@P3nUp112]

I just think it's funny that he said go make a sandwich while we set this up and I was just thinking of going to make sandwich

[@crowvelle]

I had just finished mine, before he said that.

[@bmstylee]

How's that sandwich coming?

[@Snakeman1985]

First, and it's nice to see they put something other than a 9inch in it

[@bmstylee]

Why not use a 9"? It a super strong axle.

[@paulmccoy2908]

Contrarians gonna contrary.

[@MVP11489]

Holy shit, you have no idea how a differential works do you? Power is sent to BOTH wheels on an open or positive differential at all times. Only difference is when one wheel slips, the position locks them together temporarily, the open will send all power to one wheel if either slips. But when driving normally, an open diff applies power to both wheels. Also, a posi unit DOES have spider gears! The hell you smoking? XD

[@dustinradke9200]

"Eliminates the spider gears." Lol

[@maddpeanut7524]

He was probably thinking of spool . What do you expect, he's a body guy. LOL anyway.

[@SlowSTEN]

I like how they're calling a Positrac a Posi instead of an Limited Slip Differential like EATON Themselves even call it...this isnt the 70's...know what you're talking about.

[@maddpeanut7524]

F. O.
