Crazy diff idea

[cplux]

ok maybe i'm insane but would it be possible to completely rotate the entire hilux rear housing so it was upside down and so it basically becomes a high pinion setup (with proper rotation??). Apart from the possibiliy of oil flow problems are there any other issues people can see. Brakes and perches/shock mounts are not issues for me.

ideas??

would be alot of hassle but would work out cheap for me as i am going to either do this or....run high pinion rear.

It will turn the wheels in reverse. High pinions have R and P gearcut for reverse rotation.

[cplux]

yes you are correct, I didnt really think about it too much, was just an idea.

[NICK]

so whats the problem? you have 5 reverse gears

@ NICK

That would make 1st gear even lower would'nt it

[bj on roids]

OMG that is truly a classic

[kiwilux]

cplux, have heard very bad things about running a h/p in the rear end, there was info over on pirates board

They are designed for the front ends, putting them in the rear, makes them run on the weaker coast side of the ring gear = bye bye teeth.

Whats wrong with the stocker ?????

it gets bashet to much on the d/shaft end want to raise my driveshaft basically. I had heard bad things about running 5.71 ratios too, but they have held up for over 4 years and some very hard driving (though i have snapped crownwheel bolts twice) with dual cases 1st los low and reving the vehicle off the tacho i think there is just a little torque. to test em

[bj on roids]

dude, your best bet might be to cut your perches off the housing, and rotate it up, you cna gain a significant amount of clearance this way

or alternatively, run tailshafts like myself and the boatlux (POS) and V8zuki, this will allow you to romp on it all, day, 8mm seamless hydraulic tube

[cplux]

how much for one of these?? any pics

[hypo]

BJ,

i 2 am interested in this hydraulic tube...

Yes, I would say that both you blokes need some hard core tailshafts.
What was it, one front shaft, one rear shaft, and very nearly another rear shaft in the space of an hour or so

[suprasurf]

If you turn the diff over to get clearence then just run the motor backwards 8)
I did this years ago when we fitted a bigger donk in the back of an 850 fiat

we tried our hardest to snap one mate
I was more worried about the numkber plate at the time though.

CPLUX,

If you can obtain RR gear sets, then you will need to block the gallery port that ensures the diff oils properly when it is (or was) a standard rotation, low pinion setup. This is done often on DANA diffs, I cannot comment from experience on your Toyota diff but this is worth checking out.

The alternative is avialable would you Like to Know more---------

[cplux]

go on???

Its all in the transfer case , The reveres rotation cut on the gears makes them weaker yes but not by heaps , your problem is oil delivery,.
There is a company that makes Two gear transfer cases for rear engined 4wd racing buggys.
The normal transfer in our 4x's attains its correct rotation from a three gear set , do away with one gear and bingo reverse rotation at the tranfer output.
Alternativley But i dbout there is room on a lux hemisphere is to run the ring on the other side of the pinion .
This is done with Vw transaxles to give the same effect in formular vw, or when any biulder requires to mount the engine in front of the vw box instead of behind as manufactured.
Ive been trying to find the site where i busted these transfers but cant i'll keep looking thow. :wink:

And buy CPLUX a bundy For thinking outside the aftermarket shop

[cplux]

thanks heaps for the help, much appreciated, was going to dig out whats left of my old tx case (from duals) to see what i could work out, I was thinking along these lines anyway.

[Wendle]

wouldn't the torque loading on the chassis be a little strange with the engine spinning the opposite direction to the rear pinion??

ahhh...no, you are thinking outside the box, his question, was to turn the box upside down

you are not taking into account that he has two transfer cases, (double the torque load) he also, is thinking about a V6 conversion, or V8 conversion, double the torque again, NOW that comes down to the poor rear diff, running on the coast side, a 8" toyota crown wheel and little pinion, goes BOOM, although by the time all this $$ and time is spent

you coule easily have re-welded a couple perches? NO?

a reverse t-case, with an upside down dana 60 or upside down 14 bolt WOULD likely hold up, due to them being such big diffs, the toyota gear just wouldnt be strong enough if you wanted to hammer it!

[Dozoor]

Are Bj you have a piont, Ok if you where me Bj how would you do a cop out

See if i can whezzle my way out of this one : :(

Cplux what size tires are you running ?




You do have a little bit of torque to think about cplux----------- Bring out the manitou diffs . :wink:

[hypo]

rob i think they r also talkin bout puttin the crown on the opposite side of the carrier or sumthin

to be honest, with 31s and street driven and correct lubrication, it might not be that bad BUT...you have to think he wants to do it for clearance, so by this same token he wants to run the largest tyre he can reliably run on this axle for the maximum clearance benefits

also the duals and stuff suggest a vehicle that sees more than street use!

i do not mean to sound like i am belittling you doz00r, because that transfer case suggestion (and other things you have said) have been news to me, the front wheel drive engined vehicle and so forth.... ALL this and more i have to learn from you, and i guarantee ive learnt from you, so take my childish know it all nonsense with a grain of salt

hypo...dude, crown on the other side, you'd need to notch the housing....but all i cna say is WTF? the crown would still rotate the same way relative to the pinion, either way i think it might be easier to rotate it a little bit

[Dozoor]

Weather you flip the hole case or just the centre in the case it still requires a reverse rotation transfer ,the ring on the other side of the pinion is what the do with the vw box but it has the same effect.

Check this out Could be our new 600hp high pinion,youll need some gearing in the transfer though ,at 2-1.

Doesn't the Toy 8" diff run on the coast side when its in the front, they seem to last OK

[cplux]

for peoples interest. I dont mindtrying things on my car a little different. eg have been running the 5.71 (weak) diffs in my rig for approx 5yrs and in that time have flogged the crap out of it in the bush and only succeded in snapping crownwheel bolts with no damage to gearsets.
I am still interested in doing the diff if i can figure it out.
tyres will be 35" max. either going hp in rear or this option, and if I am going to blows diffs, with 35"s duals and lockers it may as well be the cheaper to replace standard rotation ones.

Have almost figured out how to work it all so if I do it will keep yas posted.

BJ powerhouse will stay 4y-c for present but with a SC which i am hoping to be able to run off in bush.

ok...it is not being driven on all the time, often pointing uphill the front is unloaded, not much weight on it..... not high speed or heaps of load on it much....yeah they hold up well too!
