The real question is... does it blend?



But really, is it a good locker to have?

[NeverSmashaPaul]

It has survived plenty of abuse in both mine and a friends XJ. Jumping included.

[cantab27]

That's interesting .. Thanks

[4.3LXJ]

I hadn't even heard of it till now

righto I need more info...what modal Volvo , did you get a shop to fit and how hard to DIY one ....answer in kiwi please ........;)

They are coming out with two more videos.

[NeverSmashaPaul]

Like said in the video there is NO machining to be done. ⅜ inch off drivers side shaft. That's it.

It seems Eaton locker was an option in a Volvo 740 turbo. Apparently it was in the 80's and 90's models.

It looks like it's a limited slip locker. Oh and one thing I read, easy decision for a front locker in the $100 range.

[msmoorenburg]

Gm had that design in the late 70's early 80's and i've seen it engage and split the carrier. keep in mind that was in drag racing applications

$100 would be great, one guys said he found one for 45

[NeverSmashaPaul]

I paid $35.

OK, one question. Is this a locker or limited slip? I am confused by terminology being used

[denverd1]

limited slip. and looks like there's nothing manual about it.

needs one axle shaft to spin 100 RPM faster than the other to engage. disengages when both wheels spin together

one concern is a 15 year old LSD. can you rebuild the springs in these or do something to update them?

That's the thing I would be worried about. I think since I don't have the tools or know-how to remove and install gears, I would probably just spend a little more for a lunchbox locker.

[denverd1]

abe, you'd be working on the exact same parts of the diff. replacing the standard carrier with either an LSD or lunchbox locker.

[abebehrmann]

Hmmmm. It was my understanding that you don't have to remove the carrier for install of a lunchbox locker. I thought that it was called a lunchbox locker because you can practically install it in the amount of time it takes to eat lunch. Just remove spiders and replace with locker bits. I've been plenty wrong before though, just ask my girlfriend... :smiley-laughing021:

youre replacing the carrier with the locker. How long it takes depends on many factors!!

You're right Abe. With a lunchbox you just replace the spiders with it. I always thought it was named that because you open it up and trade whatever is inside for something better. :D

I'm pretty sure that's something I read in Peterson's Four Wheel and Offroad when I had a subscription as a kid, but seeing as it's been at least 15 years since I read it it's possible that it got a bit jumbled in my head. :crazy:

But I think your explanation makes a little more sense.

[denverd1]

I'll pull out the instructions later and snap you boys a pic.

although my lunchbox is for the rear....

[nickyg]

I thought it was called a lunchbox because you can keep a sandwich in there. Or at least that's what I do.

[4.3LXJ]

Just to clear it up, you can get a lunch box locker for front or rear. At least I hope so since I have both :D They use the original carrier and replace the spicer gears with four locking rings. I have a thread in the Tech Section on it

[leaftye]

Can a locker be installed with it?

[NeverSmashaPaul]

Can a locker be installed with it?

I don't understand the question.

[ArmyGuy45]

Does it work on a Dana 30 LP?

[NeverSmashaPaul]

Yes.

My understanding on the naming of a lunchbox locker, was because it can fit into your lunchbox. ?

[4.3LXJ]

Actually it can fit in one hand. Not sure how it got that name. Maybe you can put in on your lunch hour?

[denverd1]

from offroaders.com
Lunchbox Locker - A "Lunchbox" locker (or drop-in locker) is a locker mechanism that is designed to fit into the stock differential carrier replacing the spider gear set and sometimes the side gears and pinion-shaft. The nickname "Lunchbox" comes from the idea of packing your lunch in a reusable "lunchbox" where you use the same "lunchbox" and pack in a different lunch. The stock carrier is the equivalent of the "lunchbox".

[denverd1]

the turbo 740s are the ones to target. 3 on the list

[TSquared42]

I NEED one! LOL:D

[nickyg]

I NEED one! LOL:D

Me too!!! I predict a sudden depletion of the world supply of volvo rear ends.
The junkyard will look like a bunch of old ladies fighting for the last bath towel at a white sale.

[cantab27]

so its jus putting a lsd in the front ???

[prcjeep]

so its jus putting a lsd in the front ???

Thats what I understand from reading everything available.

[Mudderoy]

so its jus putting a lsd in the front ???

Yes. But it's cheap! lol

[cantab27]

Yes. But it's cheap! lol

lol cheap is good ....thought some zj had lsd front

[XJ Wheeler]

Never heard of it. I think some WJs did though. Quadradrive models maybe.

[ArmyGuy45]

So, how much are they new?

[ArmyGuy45]

Which part number is it for our dana 30's?

http://www.davebarton.com/volvorearends.html

[denverd1]

G80 for D30 is all I can find. there are G80s for all sorts of diffs so make sure it fits D30

We have made our second installment of the Volvo topic. Much has been learned. On this episode we explain and show what you are looking for when you take your trip to the junkyard.
Also a good source for which turbo models had them can be found

Happy hunting. Your feedback is what is most important.

[4.3LXJ]

One thought her on this. The D30 has two carriers for two series of ratios. Which set of ratios does this fit? It won't fit both. Either you can use stock ratios, which is suspect is the case, or 3.92 and up.

[NeverSmashaPaul]

In video 2 we discuss the different carrier ratios. There are both ratio types available.

Hey guys, thanks for the vids explaining the LSD. One concern I have is where th is LSD works best. It's a limited slip, so it takes some RPMs for it to engage. My thoughts are that for sand and mud this may be a perfect fit. For rocks however, I don't know how well this solution is going to hold up.

Mud and sand you will have the RPMs to engage both tires once you get spin on one. For rocks, getting it to engage may throw a bit of torque around in the pumpkin before you get any traction. One a good day, I think the unit will wear rather quickly from engaging under torque. On a bad day, when it hooks up you're throwing torque to the axle shaft with traction on the end of it. Could break an axle I'm thinking.

I know there are rebuild kits for these, but that's another project I'd rather not put on the list. You guys posted some action vids and were on sloppy and slick trails - I was also surprised by how much wheel spin it took to engage both tires.

Anybody have any thoughts? Or am I over thinking this? It's a clutch type setup so maybe it transfers power gradually?

Thanks again for a cheap way to LSD the Dana 30!

I can agree with that. When I crawl in rocks, I keep the rpms down in the engine and the wheels. Makes it so my D35 won't explode and disturb you fellas clear out in Texas :rolleye0012:
