Trail creeper dual transfers

[small talk]

How would the trail creeper dual tranfers be with 33's on a Ln65 diesel?

Nice and slow

G`day guys,

Please excuse my ignorance "dual transfer" does this mean one transferbox for the rear and one for the front?... so they can be independently engaged and disengaged?.. I looked it up but it wasnt clear on it`s uses.

Transfer cases are made from two basic sections, the reduction section and the 4wd section. To build a dual transfer case, two reductions boxes are bolted back to back with a dual case adapter. These two are then bolted to a 4wd section

G`day guys,

So is that a yes.. or does it seriously reduce the gear ratio like having low/low range? Or both?

[Willy Hilux]

It gives you the following options -

2wd high
2wd low
4wd high
4wd low
4wd double low

If ya add twin sticks to the rear transfer it will also give you the advantage of double low 2wd.

Can you follow this???

Single 2.28 t-case X G52 Trans 1st Gear 3.93 X 4:10 diff gears you have a crawl ratio of 37
Single 2.28 t-case X G52 Trans 1st Gear 3.93 X 4:88 diff gears you have a crawl ratio of 44

Single 4.70 t-case X G52 Trans 1st Gear 3.93 X 4:10 diff gears you have a crawl ratio of 76
Single 4.70 t-case X G52 Trans 1st Gear 3.93 X 4:88 diff gears you have a crawl ratio of 90

Dual 2.28 t-cases X G52 Trans 1st Gear 3.93 X 4:10 diff gears you have a crawl ratio of 84 or while in single low you have 37
Dual 2.28 t-cases X G52 Trans 1st Gear 3.93 X 4:88 diff gears you have a crawl ratio of 100 or while in single low you have 44

How to figure crawl ratio
Single Case---1st gear G52 trans 3.93 x 4:10 diff x 2.28 low in t-case

Dual Cases---1st gear G52 trans 3.93 x 4:88 diff x 2.28 low in 1st t-case x 2.28 low in second t-case

Toyota 4x4 Transmission 1st Gear ratio:

L43-----------------3.67 4 Speed
L45-----------------3.93 4 Speed
L50 & L52---------3.93
G52----------------3.93
G54----------------3.93
G58----------------3.92
R150F-------------3.83
R151F Turbo------4.31
W56---------------3.95
W59---------------3.95


If your running 4.7 tc gears in one of the cases you would obviously multiply that into the equation and drop one of the 2.28 if your running duals.

G`day guys,

Yes now I follow! Cheers and thanks for clearing that up now I understand. That set up would be bloody briliant for real hard core 4x4ing... Like adding a crawler gear just better.

cheers

Its great for all kinds of wheeling not just hard core. It gives the user lots of options.
