Nissan centre in Toy diffs

Post by **Slunnie** » Fri Jan 16, 2009 12:49 am

It's not uncommon for people to put Toy 8" centres into Rover axles, but has anybody used a Nissan centre into a Toy 9" centre before? At this stage I'm not about to do it, but my thoughts were that it might provide a good way to run a high pinion into a LC60 front axle if its a goer. I run LC60's axles in a Rover and this type of setup would solve some problems tailshaft problems and allow greater travel.

IMO just cut and rotate the knucles and run the shaft with a DC joint at the tcase. this allows you to run it slightly 'broken back'. Get a factory pinion oil slinger as well.

If you speak to Micka, Slunnie he will be able to give you the info on it as one of his mates had a nissan centre fitted or grafted in the front of his 100 series cruiser. Reason was he got sick of breaking the centre as 100s are bad for it (i am lead to beleive). I think they grafted the 100 axel tubes and knuckles onto the nissan centre section.

Hey thanks for this Nottie! I'd be interested to hear about it.

1Mad eng, in your theory are you turning the diff upside down to get high pinion or just rotating the diff x degrees .

That rotates the pinion angle upwards to create and equal propshaft angle between the pinion/prop and transfer/prop, but the pinion is not aligned with the transfer..... if that makes sense. They call that setup Brokenback.

If you put the 3rd member in upside down to install a low pinion as a high pinion it will reverse the drive direction.

Yep that was my next q. How do you make the axles turn the correct direction if you do an upside down install.. thnks

I Think 80ute might have something to do with putting nissan diff centers in other housings.

it's a really common modification in the winch challenge guys rigs to graft a GQ center into an 80 series housing.

There's a guy at Currumbin on the Gold Coast who does a bucketload of them.

I would have thought there'd be plenty on outers about it.

Thats true Rocktoy, I've been searching a heap on it and likewise on 80ute who seems to be the guru on it, and there is some really good information on outers about it, but it all relates to fitting a GU/GQ diff to a 80/100 axle which I think is a very different operation to fitting a GU/GQ centre to a LC60 axle. I'm anticipating the GQ/60 to be a lot simpler and something along the lines of what is done when converting a Hilux into Rover except it seems that the GQ lockers can be fitted with Toy side gears to maintain standard type toy axles.

For a bulletproof front end, go the GQ center, Airlocker, braced 80 series housing, and a set of 30 spline longfield axles, cv's and hub gears.

it would be easier and give a better / cheaper result to just extend one side of a stock 60. Nissan centers are no stronger.

Inner Axle Lengths (without birf attached, measured from end to end):

60/62 Series Passenger Side: 31.5"
80 Series Passenger Side: 34.125"
60/62 Series Drivers Side: 17.25"
80 Series Drivers Side: 17.75"

Back to the original Q?
sorry i haven't fitted a H233 in a 60 housing, but i have done a 9", they are easy, simple spacer/adapter ring. So maybe a nice TRU HI9

are the axle dia different from toy 60 - toy 80?

are the spindle ID's different from toy 60 - toy 80?

are there differences in bearing size (OD and ID) from toy 60 - toy 80?

AFAIK the only difference between the 40/60/80/Hilux is the inner lengths.

80Ute starts with a 60 Rear Housing on his 80/100 Conversions I believe.

So yes a Nissan H233B can be fitted o a 60 hosing.
