Outer Limits 4x4 Board

Hi all,

I was in contact with some people in Austria and Germany and found out the following:

1. Because Daihatsu is a subsidary of Toyota it is probably possible that the Feroza uses Toyota diffs.

2. This is a table of all usually Toyota diffs:
http://www.buschtaxi.org/downloadz/technik/diffcode_02.jpg

some translations for you (for the diagramm):
Tellerrad = ring
Triebling = pinion
Tellerraddurchmesser = diameter of ring
Differential Uebersetzung = diff ratio / undergear ratio
MIT = with
OHNE = without
Anzahl Satelitenräder = number of spidergears

There are some lines with "5.286" which could be the Feroza Ring&Pinion?

3. Part numbers
If all part numbers of the diff are known it will be no problem to compare and match daihatsu part numbers with toyota part numbers.


so far so good/bad...

I'll keep you updated....
Best,

Haasa

whoa..... do keep us posted as we are all hungry for some lockers.... if you do manage to break this mystery........ hell i'll give you the nobel prize!!!!

is that for the daihatsu rocky/ferozas? i dont see anything mentioned about daihatsu in there

Yes, they do make one- it's been mentioned before. The price works out to around AUS $3000 without freight or improt duty IIRC.

Is that each or for the pair

i'd still get one! now i only gotta work on gettin an engine installed AND a money tree to grow.......

More details here James: http://www.outerlimits4x4.com/PHP_Modul ... php?t=3915

The price will probably be a bit more attractive now with the Aussie dollar being a bit healthier.

Think I'll stick 2 my latest idea and see if my mate has still got an LSD and then later on get traction control fitted front and back
Will work out cheaper then getting a single locker and most likely work just as good

Less chance of breaking CV's 2 BTW with the traction control

I never give up...

I found out the following:

There are a lot of similarities between Toyota-Diffs and Daihatsu-Diffs:

There are Ring&Pinion avaliable from Toyota which may fit into the Feroza (which means that lockers will be also avaliable ):

Feroza:
Ring diameter front = 170mm (6,7") with 37 teeth
Ring diameter rear = 180mm (7,1") with 37 teeth
Gearing: 5.285

So we have to find out which Toyota-Modell has the following axle-code (should be located on a plate in the engine-bay of all Toyotas):
XXX.XXXX.T164.XXXX (6,7" and 4 spider-gears)
XXX.XXXX.T165.XXXX (6,7" and LSD)
XXX.XXXX.T894.XXXX (6,7" and 4 spider-gears)
XXX.XXXX.T895.XXXX (6,7" and LSD)
XXX.XXXX.E164.XXXX (7,1" and 4 spider-gears)
XXX.XXXX.E165.XXXX (7,1" and LSD)
XXX.XXXX.E894.XXXX (7,1" and 4 spider-gears)
XXX.XXXX.E895.XXXX (7,1" and LSD)

...next is to find out if
- any above Toyota-Diff ring has 37 teeth
- spidergears has 10 theeth
- diameter or spideraxle is 16mm (front) or 18mm (rear)

... then we will know if we won or we loose....

Best,
Haasa

great work haasa... keep us posted and let us know what you find out.

hmm... I rather thought you will do further investigations

ok, ok I'll do what I can do. Which means: SIR - YES - SIR !

Haasa

If u have luck with matching things up then there could possibly be a chance of doing a hybrid feroza/hilux diff and especialy for the front so I can fit an LSD
Let us know what u find out

James

Hi,

Who knows theses things about the rear axle?
- the diameter?
- how many splines?

Thanks,
Haasa

Ok just dug up some imfo ferwoaza posted ages ago about the feroza rear diff

Hope it helps



Diameter of differential cover 211mm

Rear axle is semi-floating type. 722mm for left wheel, 776mm for right wheel.

Rear Diff Info :

Final Reducation gear ratio : 5.285

Differential Ring Gear :
- Number of Teeth 37
- Outer diameter 185mm
- Gear type : Hypoid gear

Final reduction gear :
- Number of Teeth 7
- Outer diameter 57mm
- Gear type : Hypoid gear

Differential side gear:
- Number of Teeth 14
- Number of inner spline teeth 27

Number of differential pinion teeth : 10
Pinion shaft outer diameter : Ø18mm (that's an omega for some reason..)

Maybe this info will help?? Rear has a removable 3rd member just like a yota....possibilities??

Thx.

I looked into the repair-manual and this says: outer diameter 180 instead of 185 ... but the rest is the same as you wrote.

but what I'm looking for ist the axle itself. axle diameter and number of axle teeth!

...because for the use of different couplers for automatic lockers.

variant 1: find identically constructed couplers which will fit
varinat 2: make suitable couplers (if axle diameter and number of teeth are the same) using a "centre lathe" to fit the overall diameter of the coupler (don't know if this is correct name in english.. what i mean is this: http://www.mfsg.de/bilder/drehmaschine.jpg)

This company should sell the vacuum-locker from offrotec (schwarz):

Looks like a metal lathe to me (same as my father inlaw has )
