Outer Limits 4x4 Board

so ive smashed most of the teeth of the gear on the input shaft into the gearbox.. not sure what other damage is done (if any) because i havent pulled the box apart yet,
but im looking at a second hand replacement box, probably cos i figure it will be cheaper than a rebuild (cost?) ? and i wanna get it back on the road real soon.

I have a 1990 2.8t diesel
what other box's fit? does it have to be a 2.8? what years? etc..

any help appreciated

check the code on the fire wall im pretty sure it will be a g52 box which are all the same maybe minor ratio differences.

thanks, had a look on the firewall, there are a few numbers G52 is there along with G582 and a Fxxx number.
Is there a number stamped on the actual box at all?

when you say all the same, from when till when. Petrol/diesel? 4cyl/v6? etc? obviously 2wd will be differant to 4wd

Thanks again.

Fairly sure the 2wd box gears will be the same just rear case and output shaft will be different as one has to mate to transfer and other has to accept a tailshaft. Could be wrong tho someone will know if i'm on the money or not

Urs will be a G52 with front shift geardriven transfer. R150, R151, W56 boxes will all fit with the appropriate surf bellhousing. The R boxes have chaindriven transfer but r a really strong box. The older LN65 surf W56 boxes hav a topshift geardrive standard which is good and they to r pretty reliable. Both styles r run in various toyota supras.

I have a W56 plus 2LT bellhousing If u want to grab it, it has no topshift transfer tho as I used it for my duals. A topshift transfer from a old 4spd lux will fit and r normally around $100.

Thanks A1
can i use the top shift from my current 5sp? is the W56 a 5 or a 4sp?

im interested in anything atm how much are you looking for it pm if you want.

thanks again

yeah the teeth on mine are smashed aswell, every wreckers has no less than $660 for a second hand gearbox, does anyone know where I could go?
I have a 4 cylinder 95 model, really need some help. !

check rolin imports they have the 2wd g52 boxed brand new for $770 all internals the same, just the output for the tranny different, worth a look

my cousin put a cobra box in his dualcab 2.8 98/96? model to handle the turbo power and 35inch tyres better.
dont ask me what model......cobra....how....
thats just what he put in......stronger box...
cant help any more....
sorry guys

I have a g52 in mine (1993 Ln106) from a 2004 3.0L N/A diesel (5Le), but has chain drive transfer.

Pretty sure the back of the box is different as I can't get a gear drive transfer to bolt to it. Keep that in mind if you are looking around, the earlier model g52 if that's the way you go.

Do yourself a favour ...

I had much the same troubles as yourself which has now been solved 96 LN106R SAFARI turbo 33IN wranglers and I was forever blowing gearboxes. After a reco box lasted 2500km (box no 4) it was time for an upgrade. I do not drive my lux hard all day every day but when the going gets tough she goes as good as she can, I cut and pasted this from another post from a conversion i did

I have edited this post

any probs let me know

Cheers

35,000kms later still going strong

I just did this conversion and its a piece of p!ss! I believe its money well spent them G52 boxes cant handle torque from slower revving diesels i have seen them last ages behind a holden V8, I strongly suggest you get a R151 instead of a R150 1st gear in the R151 is 4.3 compared to 3.7 in the R150 and is beautiful for taking off with taller tires. I got my R151 from a 2004 factury turbo diesel (KZN165) Make sure its out of a kzn165 cause the V6 boxes from the 4runner and R151 out of the surfs had massive 3rd gear/layshaft trouble. This was fixed in the later model boxes.

I went for the R151 swap cause marks are too expensive for a dyna box and their 5.15 1st gear is too tall for what i do

Get yourself a bellhousing and drivers side engine stay (the plate that bolts onto the side of the engine to the lower part of the bellhousing cause the one from the 106 wont bolt up) from a LN130 surf. This will bolt up to your 106 and the R151
Go to marks 4x4 and (yes marks) and get yourself an adaptor plate to mount the R151 box to your original gear driven transfercase costs $575 You have to do a dry run with the adaptor as one of the bolts that mount the transfer wont clear the back of the R151 box only requires a small amount of grinding to make it clear (2 mins)

No lengthening of shafts crossemebers etc all standard if your one piece fits now it shoud still fit. I

f you find you keep smashing center bearings on your rear shaft fill the plastic gap in the bearing up with sikaflex, strengthens them up real good have not had to replace one for ages now! No more shudder on take off

Also the seal from the transfercase to the gearbox shaft that comes in marks kit does not fit and after ENDLESS calls they just kept hanging up, and left the phone on the hook. Love your work ben from marks 4X4. I just went to bearing wholesalers and got a different seal product no. 401045P that fits no problemo.

Do not do what others have done and machine out the adaptor plate to match the seal, as it is the wrong seal supplied from the USA!!!!!!!

Doing it this way it bolted straight in! Only thing is that your 4x4 selector need to be lenghtened 16mm cause the top shift on the R151 box is higher and the 4x4 shifter from the R series box is different and will not fit. I took my 4x4 gearstick to a metal fabricator and it cost me $40!

Great news is that by keeping your geardriven tc you can put twins in later on rather than using the chaindriven case, plus money saved by keeping your original tcase

This is what it cost me
LN 130 bellhousing $150
Reco R151 in plastic $1450 you dont have to get a reco there are some cheap second hand boxes around.
Marks 4x4 adaptor plate $575

Total $2115

Lux now drives fantastic no need to ride the clutch for takeoff and no more need for worry about blowing boxes miles away from home!

I also installed a safari tuff clutch which has proved to be money well spent.
