Ring/pinion pattern off...

Maybe something as simple as this can help in the future..............

I scored this installation kit some time ago cheap. Occasionally they show up on Ebay.....

Well.. honesty hoping i will not do many more of these I know at some point i will get sick of the 4.57s and drop to something else... that will probably be the last one.. i don't have a lot of years left and this should be my last car

by up you mean towards the crown? There is maybe 1/16th of a inch or less left there.. with the .072 it was almost nothing..

Towards the heel.

Yeah, it won't move that way any farther though.. at this point it is what it is

No offense intended, but I was told by someone I respected (since passed) that owned a rearend shop....
"Once a r&p is noisy, it will ALWAYS be noisy, no matter how good the next setup is".
Considering the qualit6 of offshore gears, I'm betting there's a bunch of noisy setups out there.
Gonna be fun to see how noisy my new 4.10 spool nine inch will be.

yup.. i figured since i was pulling my axles i would just check it anyway.. i have learned a lot.. I can live with it, just wanted to make sure nothing is trying to self destruct

BTW.. no offense taken I'm just trying to learn **** is all.. i know i'll be changing these gears out eventually so no big thing.

One thing for sure, a 4.57 should really perk up what ever you’re putting it in.

What's funny is it's just a low power 318 MAYBE 300hp... 9.5" convertor and those gears.. i drive 6 miles to work and don't go over 60 pretty much so figured 0-60 would be fun was just gonna leave the car bone stock and old man drive it.. but got carried away. Haven't done anything i can't change back though. If i like it i plan to do a 390 or 408... I could have done a 440 soo much cheaper and made more power, never owned a small block before though and every b-body has a 440.. but i doubt i will ever go to the track, so it's just for fun

Soo.. between not being able to get a pattern that looks like a pattern, and tonight i set it up for the final time and i set backlash at .008, on a whim decided to check different spots and found anywhere from .008 to .013... these gears are just a mess.. i think i'm just gonna replace them. (hope it's the gears causing the runout... Wasted 2 weeks on this.

Question is.. for a beater on the street, low power.. 30" tires.. get a 4.56 or drop to 4.10.. i will never do freeway or pretty much over 60 most of the time.. Also.. richmond ok or look at something else?

To be honest, I've had 4.56s and 4.11s in my 8 3/4. Currently have 3.91s. It is just as quick and fast as the two steeper gears. But then I've got a 500 hp 440.
Still, if it were me... I'd put 3.91s in your car. If you stuck a shorter tire it would act just like 4.10/4.11s, and if you do decide on a longer excursion you could use the 30s.
I've got a new set of 28" tall slicks, and if I live long enough to wear them out, I'll probably go to a 9x30 .
(For what its worth, I bought a 4.10 nine inch center for my other car... but I have 30, 31, and 33 inch tires I can use.)
Edit: richmond gears would be my choice.

I am thinking motive 4.30.. supposed to be quieter than richmond although made by the same company (Might be BS)... I had 3.91s in my challenger for 7 years but that was a big block, thinking this weak little motor would like more gear and the 4.30 will drop a couple hundred rpm for me over a 4.56.. gonna sleep on it..

I hadn't heard that about richmond/motive. My rearend guru/friend passed away a few years ago, and I'm not as up to snuff on such things as I used to be.
For what it's worth: my friend ALWAYS tried to persuade the customer to spring for OEM manufacturer gears, if possible. He said they were always easiest to set up, and most likely to be quiet.
Of course, not possible for an 8 3/4.

BTW, i bought a clamshell bearing puller and man that thing is worth every penny, although i'm glad i saw a video where you put a spare race over the bearing so it doesn't hurt the cage when pulling... I then honed out the bearing so i can pull it on and off by hand. Little tricks like that are worth gold

Please post a picture or a part number of the bearing puller you are using. Curious to see which one it is.

Motive Gear bought out Richmond about 12 years ago , you will still see Richmond gears advertised and will come in a Richmond box but the gear inside is made by Motive Gear .

This is the puller bob, i was surprised how well it worked and i also used the main pipe to hammer the new bearing on since it fit the bearing perfect (inner race of course)

Puller for carrier/pinion bearing

The pic on the top right shows the way to do it without hurting the bearing.. you put a spare race over the bearing and the 2 rings clamp it on so you can't pulling on the cage

Ahh k... i did a bunch of reading last night and people were saying although they are the same parent company the gears aren't made the same (which makes no sense to me, why make production costs higher for the same product by making them differently)

I hate Richmond gears. I three two new sets away after trying to get them set up to run quietly. Bought a set of US Gears that were supposed to be made in the United States only now they aren’t, and I’m still uncertain as to if these were made here or not. Better than Richmond but still not as quiet as OEM gears. I don’t know who you should buy from and neither does anyone else seem to know - even the professional restorer and builder of old Corvette differentials says it’s really a crap shoot anymore. Some say buy an old set of OEM gears but if you don’t know how they were originally set up it’s just guess work trying to get them to run quietly. I would probably try Dr. Differential and see what he suggests. If you think you can live with the noise then it probably doesn’t matter what you buy, even Richmond.

yeah, i'm probably going to just get 4.56 richmonds from diff.... Quicktime has 4.56s for $169 which my cheap brain is screaming at me to buy... but no idea who made them. At this point i don't think it matters though... almost wanna go 4.10 to drop the rpm a little.. but hate to lose some fun factor.

Soo.. here is something i found interesting.. i have been reading around about gear manufacturers and all that.. And read that Motive/Richmond are the same parent company and some people said they are still 2 different plants/manufacturing lines for each and other people said it's the same product with 2 names...

Then i ran into this which is less than half of what i see them for sale anywhere else..

https://www.amazon.com/Motive-Gear-C887430E-Performance-Differential/dp/B005TDSVJU?crid=QHXG2V3QFUK4&dib=eyJ2IjoiMSJ9.n1UXpvaY6bLRQWXsoe1vs6OfMMYV9bvOwevkazJOg721dqf6pCh1l6dF1Hotn7j_Br_BrtwUgvxUJxFIIXR_pIxk1I0sBM8Y5VKIdZmFXD63zfEBbmMkIUb_GcDskVDqZQ0-qXFuhFTK-SPxUr43QmFpCmkwnmW1uVTaDAoHIJVtXOWW-c4NQd8dJ_y2Do9xAtZjsMbzwSGOH1d9KrjwmUv0Cfhmmn07a1LoePdUMeY.aCoNOjn6dvQEKf2Kt-r7Mb5bQ1YwDsxNZXEqnLlJTFU&dib_tag=se&keywords=8.75%2B4.10%2Bring%2Bpinion%2B742&qid=1731074442&sprefix=8.75%2B4.10%2Bring%2Bpinion%2B742%2Caps%2C88&sr=8-9&th=1

I actually called Motive a few mins ago to ask a guy if they know of knockoffs or fakes or anything (cause anything can be now) and he said no... some vendors will blow stuff out to get numbers up and it's probably real..

I asked him bout richmond/motive and he said all Richmond are still make in italy and Motives can be from any of 4 different "Cheap" countries.. my word not his... He also confirmed motives are quieter since they aren't so performance orientated..

I just found that interesting is all and was nice to learn from the actual company. And i swear all my wrong bullshit comes from LS forums when i do google searches... can't believe ****. For $115 i might just try though.... that's a crazy price and i will never make enough power to break em.

 

[icetech]

K.. seems the 4.30 for the 742 is discontinued by motive so they are blowing them out the door.. ordered one using my amazon points, if it's crap i'm not out anything. Won't be here til mid next week.. so... i can maybe rub out some more paint while i wait
