Fragged spider gears and YOUNG, NUBILE FEMALE FLESH...

yes, the way to spam yourself to the top of the "Newer, freindlier, more depraved HAMB."

I'll see if I can dig up some ex gf *** shots, but in the meantime, we have this:



whats missing from that picture? This:




I count 12 bolt holes... but that doesnt mean its really a "12 bolt???"



Every where I live, theres oil spots...



yeah, I got a new camera, its fun...


SO...

How do I get those C-clips off? They are a PITA. Whats envolved in rebuilding this ****er? As you can see, my ring gear is fine, ***uming the pinion is too... but the thing is throwing oil out the pinion seal...

The pinion angle is ****ty, (cause the rear is too low) I thought that was the whole cause of this mess, but I see it really isnt... I'll get new springs so the rear will raise up a few inches...

So, who wants to help me rebuild it???

There was no tag on the bolts, someone long ago put a chrome cover on it, but 99% of said chrome is gone now. Anywhere else where I could look for identifying numbers?

Suggestions on places on the web I can do reasearch, learn more about this thing?

Thanks,
J

 

And yes, I (carefully) drove about 7 blocks, and paralell parked it all nice with it all fragged like that, cool ****.

 

To get the C clips out, first you need to take out the little hex head bolt that holds the center shaft in (the one thru the spiders), and pop it out. Then push the axle in and the c clip drops off. Then undo the end caps and all the gears come out.
I think I can get you the later 5 lug front and rear. I'll check tomorrow.

 

now this is a blown rear

 

yo, jason... ive got a shop manual for that generation of chevy p/u's.

not sure if its got details on rebuilding the rear end, but ill check.

if its got 12 bolts on the cover, its a 12 bolt rear.

excellant opportunity to convert to 5 lug

 

Say, is that the original rear end? If your pinion seal is leaking bad your pinion bearings are probably shot. When you take it apart carefully inspect ring and pinion. If it looks questionable, find a cheap ford 9" the right width and use it. If yours looks OK, get a posi unit(eaton), put fresh bearings in, and have fun spinning BOTH tires!

BTW cooooool truck!

 

DRR, if you have a bolt in truck rear axle, you the man... I'll totally take all the 5 lug conersion stuffs...

And yeah, Mr Plan, I'd like to borrow that manual if I may.

If I would drive dropped the thing when I got home, it too would look like that other diff, if not worse...

 

12 bolt cover don't mean ****! Count bolts on ring gear.

 

Nuh uh, bolt-in swap-o-matic time... dont have time patience or $ for much more at the moment... I have to actually GET my new welder and learn how to use it... not teaching myself on anything highway-going...

Either that, or rebuilding this one....

Sorry Mr Noname, prolly p*** on that Camaro diff you offered me...

huh?

thats the easiest way to identify what youve got?

so, youre saying a chevy rear cover with 10 bolts can be a 12 bolt? youre trippin dude...

ive used this method a few times... never had problems with the wrong parts.

 

exactly who doesn't determine a chevy rear end by 12 or 10 bolts. what the heck are you talking about

 

Actually guys, while I've never personally seen it, I have heard of what he's talking about. A 12 bolt cover with 10 bolt gears... The number of bolts on the RING GEAR is what the term 10 bolt or 12 bolt is actually referring to.

 

Exactly.

ok... so what chevys had this? sure as hell not on A-bodies.

rearends have different ring gear diameters, regardless of the bolts on the rear cover... if thats what you mean??

 

I don't actually know of the applications, but I remember reading that in a shop manual or magazine WAY back. Like I said I've never encountered it, but it supposedly exists!

 

You can put the 10 bolt carrier in a 12 bolt rear, chevy never did it but you can. It is a put it in swap, normally way cheaper if you are not keeping it. You can put 12 bolt carrier in a 10 bolt housing with a little machine work. If a crazy nut has not got a hold of a 12 bolt if it has 12 bolts on the housing it is a 12 bolt, but the acid test is the number of bolts on the ring gear.

 

Being an old vette guy we used to put 12 bolt carriers in irs vet rears all the time. A bad pinion seal is just that if you did not run it low on gear oil bearing are probably fine.

 

I'll check on the 5 bolt stuff tomorrow...you help pull, you pay the dude for it. I dont know the $$ yet, but it should be fair.
I dont think any nudie pics would help him, it would probably kill him. So I'll take those to save his life.
DRR.

 

You may already know this, but there are 2 Chev 12 bolt rears, one for p***engers and one for trucks.

Chances are you have the truck 12-bolt, but this web site has pictures of the different rear covers so you can tell for sure, http://www.differentials.com/pdfs/46.pdf

If you just want to get on the road as soon as possible, you can replace the side gears and spider gears without having to pull the ring and pinion.

Remove the c-clips as described in a previous reply, then you can remove the remains of the side and spider gears. Get some replacement gears, clean all the fragments out and put it back together.

 

is that your dog in the picture? is it a girl?

my dog is very ***** and needs to hump.

 

First time I've seen a early hood on a later model truck.

thats some annoying little rat that lives next door... barks way too much

 

Aint my dog!


I was thinking of just throwing in new spider gears...

But:

my tires are bald
My single MC brakes scare me
My front end needs to be rebuilt

So the 5 lug conversion is getting close,

AND I could buy a set of supremes!

OR I could just buy a set of spider gears...

Why do we think they broke? Just 40 years of wear? I'm not super rough on the ol girl...

Its neat huh? Once again, cannot take credit for it...

 

not river rat, neurotic guard dog... if he goes ******* in the middle of the night, I know to go out there with a machete...

 

"From 1964-82, Chevy used a variant of the Chevy 12-bolt in ½-ton trucks. Although it’s similar in outward appearance and shares the beefy 8.875 ring gear, it has a smaller 1.438-inch pinion diameter (versus 1.625) and takes specific bearings and gears."

 

Oh, and who the F will sell me the replacement spider gears? I need? Surely not napa... ???

 

if you use a 71-72 chevy 1/2t TRUCK rear, it'll be a bolt-in.
everything else WILL require a goofy set if perches and a track rod mount.
the 2nd pick tells me it's a coil sring rear suspension,correct?

 

yeah, its coil spring, but i think I just wanna slap in new spider gears, maybe a new pinion seal, and run along with the stock rear a little longer... have the 5-lug swap happen as a planned-for thing, you know?

 

That's a normal old truck 12 bolt rear end. If you look close at the picture, you can see the panhard bar mount on the very right side of the picture.

Any 12 bolt truck rear should have the spider gears you need for a quick fix.

If you convert to a 5 lug, a 71 or 72 rear end is the easiest way to go. Like 90% plus of them were coil spring trucks. Very few leaf trucks built these years. The only work will be shortening your panhard bar because the 71-72 panhard bar mounts to the top of the center section instead of the right axle tube like your truck does. I'd get the later panhard bar out of he truck you pull the rear out of.

These coil spring trucks have funny axle mount pads, unlike normal leaf spring type of trucks. That's why the 71-72 deal is so attractive. They give 5 lug, but still used the exact same axle mounting setup. Typically, a factory 6 cylinder truck has 3.73 gears and a V8 truck has 3.08 gears. Something to keep in mind when looking at donor trucks.

Don't raise your truck up just because the pinion angle is off. Go to a local spring shop (look in yellow pages under spring shop) and get some wedge shims to correct the angle some. Or, sometimes I use fender washers on the u-bolts to correct pinion angles. Put them between the axle pad and the trailing arm on the rear leg of each u-bolt.

If needed, PM me and I can maybe answer other questions for you. I'm a Chevy truck freak from way back.

 

The rear springs are torched... I have about an inch of spring travel on one side... Lots of tesion on the panhard bar, pushing the rear end over to one side, panhard bar looks arched!

This is some hokey ****, it just needs to come up a couple of inches...


So... why did this **** frag, and where can i buy NEW gears?

Or, if someone has good used pieces they wanna hook me up with??

Maybe I'll hit a couple junkyards...

Thanks,
J
